Volvo XC90 First Generation (2003-2014): The Complete Fitment Guide for Parts Sellers
The first-generation XC90 ran for twelve model years on the same P2 platform, which sounds simple until you start counting the engines. It launched with a turbocharged inline-5 and a twin-turbo inline-6, added a Yamaha-designed V8 in 2005, swapped the base engine for a naturally aspirated inline-6 in 2007, and then dropped the V8 after 2011. Each engine came with a different transmission from a different manufacturer. The 2.9L T6 used a failure-prone GM 4-speed, the 2.5T used an Aisin 5-speed, and the 3.2 and V8 used an Aisin 6-speed with its own valve body issues in early production. Add the FWD/AWD split, a major 2007 facelift that changed exterior lighting and sheet metal, a second cosmetic refresh for 2013, and diesel variants outside North America, and you have a vehicle where almost nothing can be listed as fitting "2003-2014 XC90" without qualifiers. This guide walks through every split that matters.
Brand and Platform Background
The XC90 was Volvo's first SUV, debuting at the 2002 North American International Auto Show and going on sale for the 2003 model year. It won both the North American Car of the Year (truck category) and Motor Trend's Sport/Utility of the Year for 2003. It was a massive sales success for Volvo, moving over 35,000 units in the US in its first full year and peaking near 40,000 in 2004.
The XC90 sits on the Volvo P2 platform, shared with the first-generation S80, S60, V70, and XC70. It was manufactured at Volvo's Torslanda factory in Gothenburg, Sweden, throughout its production life. At the end of 2014, Swedish production ended and the tooling was moved to China, where a lightly updated version continued as the "Volvo XC Classic" for the Chinese domestic market. The second-generation XC90, on the completely different SPA (Scalable Product Architecture) platform, arrived for the 2016 model year in the US (no 2015 model year was offered in the US market).
Ownership Changes
The XC90's production span crosses a major corporate ownership change:
Ford era (2003-2010): Volvo Cars was a subsidiary of Ford Motor Company. The XC90 shares some Ford-era corporate supplier relationships, including the GM-sourced transmission used with the 2.9L T6.
Geely era (2010-2014): Zhejiang Geely Holding Group acquired Volvo Cars from Ford in August 2010. Under Geely ownership, the first-gen XC90 continued largely unchanged while the second generation was developed.
For parts purposes, the ownership change itself does not create fitment splits. Parts catalogs list the vehicle under Volvo regardless of corporate parent. However, the ownership transition explains why the first-gen XC90 received only minor cosmetic updates from 2010 through 2014 rather than a full redesign: Geely was investing in the all-new SPA platform rather than refreshing the aging P2.
Complete Engine and Drivetrain Reference
This is the most critical section for fitment. The first-generation XC90 used four completely different engines across its twelve-year run in North America, each paired with a different transmission. These are not interchangeable powertrains.
Engine 1: 2.5L Turbocharged Inline-5 (B5254T2) - "2.5T"
Years offered (US): 2003-2006
Displacement: 2,521 cc
Configuration: Inline 5-cylinder, DOHC, 20-valve, turbocharged and intercooled
Output: 208 hp, 236 lb-ft
Transmission: Aisin Warner AW55-50SN/51SN, 5-speed automatic
Drive: FWD standard, Haldex AWD optional
Notes: This is the base engine for the early XC90. The 5-cylinder shares its architecture with the engines in the S60, V70, and XC70 of the same era (P2 platform). The AW55-50/51 transmission's solenoids were upgraded around mid-2006 production, and the AWD angle gear (bevel gear) coupler sleeve was also upgraded to a harder material around the same time. Pre-upgrade units are more prone to solenoid sticking and angle gear spline stripping.
Engine 2: 2.9L Twin-Turbo Inline-6 (B6294T) - "T6"
Years offered (US): 2003-2005
Displacement: 2,922 cc
Configuration: Inline 6-cylinder, DOHC, 24-valve, twin-turbocharged and intercooled
Output: 268 hp, 280 lb-ft
Transmission: GM 4T65E-V (4-speed automatic, Volvo-modified version of the GM 4T65 transaxle)
Drive: AWD only (Haldex)
Notes: This is the performance engine for the early XC90. The GM 4T65E-V transmission is the single most failure-prone component in the entire first-generation XC90 lineup. It was not designed for the weight and torque demands of the XC90, and Volvo faced class-action litigation over premature transmission failures. The 4T65E-V is a GM product with Volvo-specific programming and modifications, and it does not directly interchange with the standard GM 4T65E used in vehicles like the Chevrolet Impala or Pontiac Grand Prix without ECU/TCM reprogramming. The T6 engine was dropped after 2005 in North America, replaced by the V8 as the performance option.
Engine 3: 4.4L V8 (B8444S) - "V8"
Years offered (US): 2005-2011
Displacement: 4,414 cc
Configuration: V8, DOHC, 32-valve, naturally aspirated, aluminum block and heads
Output: 311 hp (initially rated 288 hp in early 2005, revised to 311 hp), 325 lb-ft
Transmission: Aisin Warner TF-80SC, 6-speed automatic ("Geartronic")
Drive: AWD only (Haldex)
Notes: The B8444S was designed by Yamaha Motor Company and is unique to Volvo. It does not share its architecture with any other manufacturer's V8. It is a compact, lightweight, high-revving engine that fits transversely in the XC90's engine bay. The TF-80SC transmission paired with the V8 had documented valve body bore wear issues in early production (serial numbers before 06J). Transmissions with serial numbers starting 06J and later received redesigned valve bodies. The V8 was dropped after the 2011 model year due to poor fuel economy in an increasingly efficiency-focused market.
Engine 4: 3.2L Naturally Aspirated Inline-6 (B6324S/B6324S2) - "3.2"
Years offered (US): 2007-2014
Displacement: 3,192 cc
Configuration: Inline 6-cylinder, DOHC, 24-valve, naturally aspirated
Output: 235 hp initially (2007), revised to 240 hp (2008-2014), 236 lb-ft
Transmission: Aisin Warner TF-80SC, 6-speed automatic ("Geartronic")
Drive: FWD standard, Haldex AWD optional
Notes: The 3.2 replaced both the 2.5T and the twin-turbo T6 as the base engine starting in 2007. After the V8 was dropped following 2011, the 3.2 became the only engine offered on the US-market XC90 for 2012-2014. The 3.2 shares the TF-80SC transmission with the V8, but with different calibration and potentially different final drive ratios. Like the V8 application, early TF-80SC units (pre-serial 06J) have the valve body bore wear issue.
Diesel Engines (Non-US Markets)
The XC90 was also offered with diesel engines in European and other markets. These are relevant for parts sellers who handle imported or gray-market vehicles:
D5 (2.4L 5-cylinder turbo diesel, D5244T/T4/T18): Multiple output levels from 163 hp to 200 hp depending on year and tune. Paired with AW55-50/51SN 5-speed auto (early) or TF-80SC 6-speed auto (later), plus a 6-speed manual option in some markets.
2.4D (2.4L 5-cylinder turbo diesel): Lower-output version of the D5, 163 hp. Limited markets.
D3 (2.4L 5-cylinder turbo diesel, lower output): Offered from 2011 in certain European markets.
D4 (2.0L 4-cylinder turbo diesel): Offered from 2012 in certain European markets. Uses a smaller engine than all other XC90 applications.
Diesel engine parts do not interchange with gasoline engine parts. The diesel XC90 also uses different engine mounts, exhaust systems, fuel systems, and ECU configurations. If a buyer is ordering for a diesel XC90, every engine-related part must be verified against the specific diesel engine code.
The 2007 Facelift: Pre-Facelift vs. Post-Facelift
The 2007 model year brought the most significant visual and mechanical changes in the first-generation XC90's production run. For parts fitment, the pre-facelift (2003-2006) and post-facelift (2007-2014) are often treated as two separate vehicles for body, lighting, and interior components. The facelift debuted at the April 2006 New York Auto Show.
Exterior Changes (2007)
Headlights: Completely redesigned. Pre-facelift headlights are not compatible with post-facelift headlights. The mounting points, wiring connectors, and lens shapes are different. Adaptive bi-xenon headlights became available for the first time in 2007.
Front bumper/fascia: Revised design with a more prominent lower grille shield and body-color side moldings (previously black plastic).
Grille: Updated design.
Taillights: Redesigned with squared reversing light lenses. Pre-facelift and post-facelift taillights do not interchange.
Door handles: Changed to body-color (previously black on some trims).
Side moldings: Changed to body-color across all trims.
Wheels: New designs offered.
Interior Changes (2007)
Additional metallic trim accents.
V8 models received upgraded instrumentation.
Revised center console and controls.
Mechanical Changes (2007)
The 2.5T inline-5 was dropped entirely. Replaced by the 3.2L inline-6 as the base engine.
The twin-turbo T6 inline-6 was already gone (dropped after 2005).
The transmission for the base model changed from the Aisin 5-speed (with the I-5) to the Aisin TF-80SC 6-speed (with the I-6).
Suspension was re-tuned.
TPMS (tire pressure monitoring system) became standard.
BLIS (Blind Spot Information System) with mirror-mounted cameras became available.
MP3 input jack became standard.
Later Updates (2008-2014)
2008: Auto-dimming rearview mirror became standard. "Special Edition" trim debuted.
2009: New rear logo with larger "VOLVO" lettering and wider letter spacing. V8 Sport model dropped.
2010: Painted wheel arches became standard across all models (previously an option on some trims). New, larger circular Volvo logo on front grille. Standard third-row seating. Rear parking assist added.
2011: Bluetooth integration and satellite radio became standard. Last year for the V8 engine.
2012: V8 dropped from the lineup. New LED taillights available on some trims (lower trims retained pre-LED style). The 3.2 became the sole engine for all US-market XC90s.
2013: Standard LED daytime running lights and LED taillights across all trims. Body-color bumpers, rocker panels, and silver trim replaced black plastic trim elements. Revised interior.
2014: Final model year. Minor trim updates. Base price dropped to $39,700.
Step-by-Step Fitment Splits
Split 1: Engine (Primary Split)
This is the single most important fitment attribute. The first-gen XC90 used four different gasoline engines in the US market, and each one requires different parts for every engine-related system:
2003-2006 2.5T: Inline-5, turbocharged, 2.5L (B5254T2)
2003-2005 T6: Inline-6, twin-turbo, 2.9L (B6294T)
2005-2011 V8: V8, naturally aspirated, 4.4L (B8444S)
2007-2014 3.2: Inline-6, naturally aspirated, 3.2L (B6324S/S2)
Nothing interchanges between these engines: not oil filters, not air filters, not serpentine belts, not spark plugs, not ignition coils, not motor mounts, not exhaust manifolds, not cooling system components. Even the engine oil specification may differ. Treat each engine as a completely separate vehicle for purposes of engine-related parts.
Split 2: Transmission
Three different automatic transmissions were used, each from a different manufacturer:
GM 4T65E-V (4-speed): Used exclusively with the 2.9L T6 (2003-2005). This is a GM product. Transmission fluid, filter, seals, and rebuild components come from GM/aftermarket GM transmission suppliers, not from Volvo or Aisin parts channels.
Aisin Warner AW55-50SN/51SN (5-speed): Used with the 2.5L I-5 (2003-2006) and the 2.4L D5 diesel (early models). This is an Aisin product shared with other Volvo P2 cars (S60, V70, S80). The solenoids were upgraded mid-2006. The AW55-50/51 does not have an externally accessible filter; the filter is internal and requires disassembly to service.
Aisin Warner TF-80SC (6-speed): Used with the 3.2L I-6 (2007-2014) and the 4.4L V8 (2005-2011), as well as later D5 diesel models. This is also an Aisin product, but it is a completely different transmission from the AW55-50/51. It uses different fluid, different seals, different solenoids, and a different valve body. Early TF-80SC units (serial numbers before 06J, affecting 2006-2008 models) had valve body bore wear issues. Replacement valve bodies for early units are available from aftermarket rebuilders.
A transmission filter, pan gasket, solenoid, or fluid listed for the AW55-50/51 will not fit the TF-80SC or the 4T65E-V, and vice versa. Always confirm the specific transmission type before shipping.
Split 3: Drive Configuration (FWD vs. AWD)
FWD (front-wheel drive): Available with the 2.5T (2003-2006) and the 3.2 (2007-2014). No angle gear, no center driveshaft, no Haldex rear differential, no rear differential, no rear CV axles.
AWD (all-wheel drive): Standard on the T6 and V8. Optional on the 2.5T and 3.2. AWD-equipped XC90s have an angle gear (also called bevel gear or transfer case), a center driveshaft, a Haldex electronically-controlled rear differential with its own oil pump, fluid, and filter, and rear CV axles.
This split affects a huge range of parts: axle shafts, differential components, driveshaft, angle gear assembly and coupler sleeve, Haldex pump and filter, suspension geometry components (the rear subframe may differ), exhaust routing (the center driveshaft runs under the vehicle), and even some body undercarriage panels. An FWD-specific exhaust may not clear the driveshaft on an AWD vehicle. A rear differential part obviously has no application on a FWD vehicle.
The AWD angle gear coupler sleeve is a known failure item, especially on V8 models where the higher torque accelerates wear. The sleeve uses a softer metal than the splines it connects to, acting as a deliberate sacrificial component. Replacement sleeves and seal kits are a regular service item on high-mileage AWD XC90s.
Split 4: Pre-Facelift vs. Post-Facelift Body (2003-2006 vs. 2007-2014)
All exterior lighting (headlights, taillights, fog lights), front and rear bumper covers, grille assemblies, side moldings, mirror assemblies (BLIS-equipped mirrors were introduced with the facelift), and many interior trim pieces differ between the two production eras. Sheet metal (fenders, hood, doors) is generally the same, but verify trim-specific pieces.
A secondary body split occurs for 2013-2014, when LED DRLs and LED taillights became standard across all trims, body-color bumpers replaced black plastic, and other trim elements were updated. While many 2007-2012 body parts still fit 2013-2014 vehicles, the exterior trim pieces, taillight assemblies, and DRL assemblies specific to the 2013-2014 refresh will not fit 2007-2012 vehicles.
Split 5: Trim Level and Option Packages
US-market trim levels evolved across the production run. Key trim-related fitment distinctions:
Base vs. Sport vs. R-Design: Wheels, suspension components (Sport/R-Design may have stiffer springs and dampers), exterior trim (different grille inserts, exhaust tips, body kit elements), and interior trim (seats, steering wheel, shifter) differ.
Standard vs. Premium/Executive packages: Upgraded audio (Dynaudio premium audio has different head unit, amplifier, and speaker locations), navigation system, seat materials, sunroof/moonroof.
Special Edition / Ocean Race Edition (2006): Unique interior trim, exterior color, and badging. Limited to 800 units worldwide.
BLIS-equipped vs. non-BLIS mirrors (2007+): Mirror housings with BLIS cameras are different from standard mirrors.
Adaptive headlights vs. standard headlights (2007+): Different headlight assemblies, wiring, and control modules.
LED taillights vs. conventional taillights (2012+): LED tail assemblies became available on upper trims for 2012 and standard on all trims for 2013. The LED assemblies have different connectors and may require different wiring.
Split 6: Seating Configuration (5-Seat vs. 7-Seat)
The XC90 was primarily marketed as a 7-passenger, 3-row vehicle, but some configurations were offered as 5-passenger with no third row. From 2010 onward, the third row became standard in the US market. Parts affected:
Third-row seat assemblies, seatbelts, and mounting hardware
Third-row side curtain airbag modules (7-seat vehicles have additional airbag coverage for the third row)
Cargo area trim panels and floor panels (different between 5-seat and 7-seat configurations)
Biggest Return Traps
Trap 1: Listing Engine Parts as Fitting "2003-2014 XC90" Without Engine Specification
Why they get returned: A seller lists an oil filter, serpentine belt, or ignition coil as fitting "Volvo XC90 2003-2014." The XC90 used four different gasoline engines (plus diesels in other markets) across that span. An oil filter for the 2.5T inline-5 does not fit the 3.2 inline-6, the V8, or the T6. A serpentine belt for the 3.2 will not work on the V8. The customer orders based on year alone and receives the wrong part.
How to stop returns: Always specify the engine in the listing: "Fits 2007-2014 XC90 3.2L I-6" or "Fits 2005-2011 XC90 4.4L V8." Never list an engine part as fitting the full year range unless you have confirmed it genuinely crosses all four engines, which is extremely rare.
Trap 2: GM 4T65E Transmission Parts Listed for "XC90 Automatic Transmission" Without Specifying T6
Why they get returned: The GM 4T65E-V was used only with the 2.9L T6 engine (2003-2005). It is a completely different transmission from the Aisin AW55-50/51 used with the 2.5T and the Aisin TF-80SC used with the 3.2 and V8. A seller listing a "Volvo XC90 transmission filter" may ship a GM 4T65E filter to a customer with a 2005 2.5T (which uses the Aisin AW55-50/51 and has an internal, non-serviceable filter). Or they ship an Aisin TF-80SC solenoid to a T6 owner whose car has the GM unit.
How to stop returns: Always specify the transmission by name and the associated engine. "Fits XC90 with GM 4T65E (2.9L T6 only)" or "Fits XC90 with Aisin TF-80SC (3.2L and V8 models)." Never assume all XC90 automatics are the same.
Trap 3: Pre-Facelift Headlights or Taillights Shipped for Post-Facelift Vehicles (and Vice Versa)
Why they get returned: The 2007 facelift completely changed the headlight and taillight designs. A 2003-2006 headlight assembly will not mount in a 2007-2014 vehicle. A 2013-2014 LED taillight assembly will not plug into a 2007-2012 vehicle without adaptation. The buyer orders by year range but the listing does not specify the facelift break.
How to stop returns: Always split lighting listings at the 2006/2007 boundary. For taillights, add a second split at 2012/2013 for LED vs. conventional. Include a note: "Does not fit 2007+ facelift models" or "Fits 2007-2012 only, does not fit 2013-2014 LED-equipped models."
Trap 4: FWD Parts Listed for AWD Vehicles (Especially Exhaust and Drivetrain)
Why they get returned: A catalytic converter, exhaust pipe, or center section designed for the FWD XC90 will not clear the center driveshaft on an AWD XC90. Conversely, a buyer with a FWD vehicle receives an AWD-specific exhaust section with extra clearance for a driveshaft that does not exist on their vehicle (it may still physically fit, but the routing and hanger positions can differ). Worse, a buyer with an AWD vehicle orders an "XC90 rear axle" and receives front CV axles because the seller assumed all XC90s are FWD.
How to stop returns: Always specify FWD or AWD for exhaust components, axle shafts, differential parts, subframe components, and any undercarriage items. If the listing is for an AWD-specific component (angle gear sleeve, Haldex filter, rear driveshaft), state "AWD only" prominently.
Trap 5: TF-80SC Valve Body Parts Without Early/Late Production Split
Why they get returned: The Aisin TF-80SC 6-speed automatic used in the V8 and 3.2 models had a documented valve body bore wear problem in early production. Transmissions with serial numbers before 06J have the original valve body design; serial numbers 06J and later have the redesigned valve body. A buyer purchasing a replacement valve body for a 2006-2008 XC90 needs the updated design. If the seller ships an original-design valve body (or doesn't specify which version they are selling), the buyer may receive a part that will repeat the same failure.
How to stop returns: For TF-80SC valve body and related components, specify whether the part is the original or updated design, and note the affected model years (2006-2008 XC90 V8 and 3.2). Reference the 06J serial number threshold if possible.
Trap 6: Angle Gear / Bevel Gear Confusion with "Transfer Case"
Why they get returned: Volvo's AWD system uses a component variously called the "angle gear," "bevel gear," or "transfer case" in different sources. These are all the same part: the 90-degree gearbox that bolts to the transversely mounted transmission and redirects power to the rear driveshaft. A buyer searching for a "Volvo XC90 transfer case" may not find a listing for "Volvo XC90 angle gear" and vice versa. Additionally, the coupler sleeve (the internally splined collar connecting the transmission output to the angle gear input) is a separate serviceable component, and a buyer ordering an "angle gear" may expect the sleeve to be included.
How to stop returns: Cross-list the component under all three names: angle gear, bevel gear, and transfer case. Clearly state whether the coupler sleeve is included or sold separately. Note that the angle gear assembly does not have individually serviceable internal gears from Volvo; it must be replaced as a unit if the internal gears are damaged. Bearings and seals are serviceable.

Specific options (if applicable): BLIS mirrors, adaptive headlights, LED taillights, Dynaudio audio, navigation
Buyer Confirmation Prompts
Before shipping any part for a first-gen XC90, confirm:
"What is your model year?"
"Which engine does your XC90 have: 2.5T, T6, 3.2, or V8?" (If outside North America: "Is it a gasoline or diesel model?")
"Is your vehicle front-wheel drive or all-wheel drive?"
"For body and lighting parts: Is your XC90 a 2003-2006 (pre-facelift) or 2007-2014 (facelift)?"
"For 2012-2014 taillight orders: Does your vehicle have LED taillights or conventional bulb taillights?"
"For transmission parts: Do you know which transmission you have?" (If not, the engine will tell you: T6 = GM 4T65E; 2.5T = Aisin 5-speed; 3.2 or V8 = Aisin 6-speed.)
Quick Identification Guide
Engine identification from the outside:
2.5T (2003-2006): Look for "2.5T" badge on the rear. Under the hood, the inline-5 has five visible intake runners and is distinctly narrower than a V8 or inline-6. The 2.5T came with the option of FWD or AWD.
T6 (2003-2005): Look for "T6" badge on the rear. Under the hood, the inline-6 is longer than the inline-5 and has twin turbocharger plumbing. The T6 was always AWD.
V8 (2005-2011): Look for "V8" badge on the rear. Under the hood, the V8 is wider and has a distinctive Yamaha-designed intake manifold with "VOLVO" cast into the center cover. The V8 was always AWD.
3.2 (2007-2014): Look for "3.2" badge on the rear. Under the hood, the naturally aspirated inline-6 has no turbo plumbing. The 3.2 could be FWD or AWD. After 2011, if the rear badge just says "XC90" without an engine badge, it is a 3.2 (it was the only engine offered 2012-2014).
FWD vs. AWD from outside: Look under the vehicle for a center driveshaft running from the front to the rear axle. If there is no center driveshaft, it is FWD. The rear suspension setup will also differ visually: AWD vehicles have a rear differential housing at the center of the rear axle. Some vehicles also carry an "AWD" badge on the tailgate.
Pre-facelift vs. post-facelift from the front: The easiest visual tell is the headlights. Pre-facelift (2003-2006) headlights have a more rounded inner shape and the turn signal indicator is integrated lower in the housing. Post-facelift (2007-2014) headlights are more angular with a distinct clear-lens design and a larger, more sculpted housing shape. The lower front bumper also changed: pre-facelift has a simpler design; post-facelift has a more prominent silver lower grille shield.
2013-2014 refresh from 2007-2012: The 2013-2014 models have standard LED daytime running lights (visible as a distinct LED strip), body-color bumpers and rocker panels (earlier models may have black plastic), and standard LED taillights. If the taillights are LED across all positions (not just one section), it is likely a 2013-2014.
Parts Sourcing Notes
The first-generation XC90 benefits enormously from its P2 platform sharing and its high production volume (over 630,000 units sold in the US alone across twelve years). Parts availability is generally excellent across all categories.
P2 platform cross-references: Many suspension, steering, and brake components cross-reference to other Volvo P2 cars: the S60 (2001-2009), V70/XC70 (2001-2007), and S80 (1999-2006). The XC90 is heavier than these sedans and wagons, so spring rates and damper valving will differ, but hard parts like control arm bushings, ball joints, tie rod ends, wheel bearings, and some brake components may cross. Always verify by part number rather than assuming compatibility based on platform alone. The XC90's longer wheelbase and higher ride height mean that some P2 suspension components are unique to the XC90.
Engine cross-references: The 2.5L B5254T2 inline-5 is shared with the S60 2.5T and V70 2.5T. The 3.2L B6324S inline-6 is shared with the S80 3.2. The 4.4L B8444S V8 is shared with the S80 V8 AWD. Engine internals, sensors, and accessories may cross between XC90 and the corresponding sedan application, subject to part number verification. The 2.9L B6294T twin-turbo inline-6 is also found in the S80 T6, but with a different transmission (the S80 T6 used the GM 4T65E as well, so transmission parts do cross between XC90 T6 and S80 T6).
Transmission cross-references: The AW55-50/51 is used across many Volvo P2 applications. The TF-80SC is used in the S60R, V70R, S80 V8, and later S80/V70/XC60/XC70 models. The GM 4T65E-V is specific to the Volvo T6 applications (XC90 T6 and S80 T6) and does not directly interchange with standard GM 4T65E applications without modification.
Haldex AWD components: The Haldex coupling used in the XC90's AWD system is shared with other Haldex-equipped Volvos (XC70, S60 AWD, V70 AWD). The Haldex oil, filter, and pump are maintenance items. Multiple Haldex generations were used during the XC90's production run, so verify the specific Haldex generation by model year.
OEM and aftermarket availability: Volvo OEM parts are available through Volvo dealerships. Major aftermarket suppliers for the first-gen XC90 include IPD (ipdusa.com, a long-established Volvo specialist), FCP Euro (fcpeuro.com, offering a lifetime replacement guarantee on wear parts), Skandix, and URO Parts. Salvage yards are also an excellent source given the XC90's high production volume.
