Parts for your 2012 Toyota Mark x-Thrust bearing

2012 Toyota Mark X — Is a thrust bearing relevant?

Based on Toyota technical publications, a standalone clutch “thrust bearing” is not applicable to the 2012 Toyota Mark X. The X130-series Mark X (GRX130/133) was supplied with a 6‑speed automatic transmission (A760E/A761E) only, there’s no factory manual clutch in this model year. Toyota’s New Car Features (NCF) for the Mark X X130 and the A760E/A761E Repair Manual sections both describe an electronically controlled 6‑speed auto and make no provision for a clutch release/thrust bearing typical of a manual gearbox.

There is, however, an engine crankshaft thrust bearing function inside the V6 engines used (4GR‑FSE 2.5L and 2GR‑FSE 3.5L). In the Toyota GR‑series Engine Repair Manual, crankshaft endplay is controlled by thrust surfaces integrated with the main bearing set (commonly at the No. 3 main journal on GR engines). That thrust bearing is an internal component addressed only during engine overhaul. It’s not a routine service item and won’t appear as a separate “thrust bearing” listing for regular maintenance.

So if someone’s hunting a thrust bearing for a 2012 Mark X as a clutch part, it’s not used because the car runs an autobox with a torque converter, not a manual clutch. If the concern is about axial movement of the crankshaft, that lives under the banner of engine main bearings and thrust clearance checks—work guided by the GR‑series Repair Manual specs and carried out during engine teardown.

For everyday servicing, there’s no thrust bearing to replace on this model. Sensible care focuses on high‑quality engine oil at the right intervals, keeping transmission fluid in good nick per Toyota schedules, and addressing any driveline vibrations early. If a workshop suspects excessive crankshaft end float (rare on well‑maintained GR engines), they’ll measure thrust clearance against manual specs and proceed with engine bearing service only if readings are out of tolerance.

• Transmission: A760E/A761E 6‑speed automatic — no clutch release/thrust bearing (Toyota NCF/Repair Manual).
• Engines: 4GR‑FSE/2GR‑FSE — thrust function integrated in main bearings, checked during overhaul (Toyota GR‑series Repair Manual).

Popular questions about 2012 Toyota Mark X thrust bearing

Does a 2012 Mark X have a clutch thrust (release) bearing?

No. The 2012 Mark X is fitted with a 6‑speed automatic, so there’s no manual clutch or release/thrust bearing to service. Any parts listing for a “clutch thrust bearing” won’t apply to this model year and drivetrain.

Is there a thrust bearing in the engine, and does it need regular servicing?

Yes, the crankshaft’s endplay is controlled by thrust surfaces in the main bearing set inside the GR‑series V6. It isn’t a routine maintenance item. It’s only inspected and replaced during engine overhaul, following thrust clearance specifications in the Toyota GR‑series Engine Repair Manual.

What signs point to possible crankshaft thrust bearing wear?

It’s uncommon, but red flags include noticeable fore‑aft movement of the crank pulley, metallic debris in the oil, or abnormal noises from the front of the engine. A technician would verify by measuring crankshaft end float against the spec, if it’s beyond limits, the engine would need bearing service.
