Parts for your 2007 Toyota Mark x-Thrust bearing

2007 Toyota Mark X thrust-bearing — is it relevant?

For the 2007 Toyota Mark X (GRX120/121), a serviceable “thrust bearing” as people commonly mean it in Australia and New Zealand — the clutch thrust/release bearing — isn’t fitted. Technical sources including the Toyota Electronic Parts Catalogue for GRX120-series Mark X, Toyota New Car Features for the 4GR‑FSE/3GR‑FSE driveline, and the factory Repair Manual specify the Mark X was delivered with Aisin automatic transmissions (A650E or A960E) and no manual clutch assembly. With no clutch, there’s no throwout/thrust bearing to replace during regular servicing.

Why the part isn’t used comes down to the transmission design. The Mark X uses a torque converter automatic, so it doesn’t have a clutch pressure plate, release fork, or a release/thrust bearing. While there are axial/thrust bearings inside the automatic transmission and thrust faces inside the engine, these are internal components and not serviced like a typical clutch release bearing. Toyota’s EPC for GRX120 shows no “Clutch – Release Bearing” category, backing up that it’s not a service item on this model year.

It’s worth noting the V6 engines (4GR‑FSE/3GR‑FSE) do have crankshaft thrust bearings integrated into the main bearing set, but that’s an internal engine part only addressed during an engine rebuild or if diagnosing abnormal crankshaft endfloat — not something listed as a routine “thrust-bearing” replacement.

If someone’s chasing a noise they’d normally blame on a clutch thrust bearing, the likely culprits on a 2007 Mark X are elsewhere:

• Accessory drive: idler/tensioner pulleys or the A/C compressor clutch
• Wheel bearings or the prop shaft centre support bearing
• Automatic transmission torque converter or front pump (specialist diagnosis needed)

Practical tip: if the noise changes with road speed rather than engine revs in Park/Neutral, think wheel bearings or driveline, if it changes with revs at a standstill, think accessory pulleys or the A/C clutch. For transmission-related whine, shudder, or metal-in-fluid, get a transmission specialist to assess before it gets spendy.

So, if a parts finder shows “2007-toyota-mark-x/thrust-bearing,” it’s not applicable for this model year’s factory setup. Choose parts based on the GRX120 auto driveline, and if you’re rebuilding the engine or gearbox, refer to the Toyota Repair Manual procedures for internal thrust components and endfloat specs.

Popular questions about 2007 Toyota Mark X thrust-bearing

Does a 2007 Mark X have a clutch thrust (release) bearing?
No. The GRX120 Mark X was fitted with Aisin automatic transmissions (A650E/A960E) from factory, so there’s no manual clutch and no clutch thrust/release bearing to service or replace. Toyota’s EPC and factory manuals list auto trans components and a torque converter, not a clutch release setup.

What could cause a “thrust-bearing-like” noise on a 2007 Mark X?
Common sources are the serpentine-belt idler or tensioner pulleys, the A/C compressor clutch, wheel bearings, the prop shaft centre support bearing, or internal automatic transmission components like the torque converter. Matching the noise to engine revs vs road speed helps narrow it down.

Does the Mark X engine have a thrust bearing at all?
Yes, the 4GR‑FSE/3GR‑FSE engines use crankshaft thrust bearings as part of the main bearing set, but they’re internal. They’re only inspected or replaced during engine work, following Toyota Repair Manual procedures for endfloat measurement and bearing selection.
