Parts for your 2007 Subaru Tribeca-Thrust bearing

2007 Subaru Tribeca thrust-bearing — is it actually a thing?

The 2007 Subaru Tribeca runs a 5-speed electronic automatic transmission (commonly known as the 5EAT) paired with Subaru’s H6 engine. On this model there’s no manual gearbox option, which means there’s no external clutch assembly and therefore no clutch thrust (throw-out) bearing to service or replace. Put simply: a clutch-style thrust-bearing isn’t fitted to the 2007 Tribeca.

This conclusion is backed by technical sources: the 2007 Tribeca Owner’s Manual specifies a 5-speed automatic for all variants, Subaru’s factory Service Manual for the 5EAT covers a torque-converter automatic with no clutch release mechanism, and Subaru Australia’s 2007 brochure/spec sheet lists “5-speed Sportshift automatic” as standard across the range. From a drivetrain fundamentals standpoint, a thrust/throw-out bearing is a manual-transmission part used to actuate the clutch — something the Tribeca doesn’t have.

Worth noting for completeness: “thrust bearing” can also describe internal bearings that control axial loads inside engines and automatic transmissions. The Tribeca’s EZ-series H6 uses thrust faces within its main bearings to manage crankshaft end float, and the 5EAT contains internal thrust bearings/washers. These are sealed, internal components and not routine service items. If there’s unusual axial play in the crank or transmission-related noise, diagnosis and repair sit with specialist engine or automatic-transmission services rather than regular servicing.

For owners chasing a noise they suspect is a “thrust-bearing” issue (often a term borrowed from manual cars), it’s smarter to look at likely Tribeca culprits: accessory drive pulleys, idlers and the A/C clutch, wheel bearings, engine and transmission mounts, or automatic transmission fluid condition. Keeping the ATF changed to the correct Subaru specification at the recommended intervals, and inspecting belts, pulleys, and mounts, will head off most driveline grumbles on this model.

Popular questions about 2007 Subaru Tribeca thrust-bearing

Does a 2007 Subaru Tribeca have a clutch thrust bearing?
No. The 2007 Tribeca uses a 5-speed automatic (5EAT) with a torque converter, so there’s no clutch pedal and no clutch thrust/throw-out bearing. If someone mentions a “thrust bearing” on this model, they’re usually thinking of manual-transmission hardware that doesn’t apply here.

Are there any thrust bearings in the Tribeca at all?
Yes, but they’re internal. The H6 engine has thrust faces integrated into the main bearings to control crankshaft end float, and the 5EAT automatic contains internal thrust bearings/washers. These aren’t routine service items and are only addressed if there’s a confirmed internal fault.

What should be serviced to prevent “thrust-bearing‑like” noises?
Focus on what actually wears on this model: change the ATF to the correct Subaru spec at the advised intervals, inspect accessory belts, idler/tensioner pulleys and the A/C clutch, check engine/trans mounts, and assess wheel bearings. Whining or shudder that changes with gear selection can point to transmission fluid condition, pump, or torque converter health — best checked by an auto-trans specialist.
