Parts for your 2006 Toyota Highlander-Thrust bearing

2006 Toyota Highlander thrust bearing — is it a thing?

Short answer: as a stand-alone service part, a “thrust bearing” isn’t used on the 2006 Toyota Highlander. Toyota’s own technical literature shows this model range was built with automatic or eCVT hybrid transaxles, so there’s no manual clutch and no clutch thrust/throwout bearing to service.

Technical sources backing this up include the Toyota Repair Manual for the 2006 Highlander/Kluger, the Toyota Electronic Parts Catalog (EPC), Aisin transaxle service information for the U241E (2.4L) and U151E/U151F (3.3L V6) automatics, and Toyota New Car Features documentation for the Hybrid’s eCVT. Across those references, there’s no listing for a clutch release/thrust bearing on this vehicle.

Here’s what it runs from factory:

• 2.4L 2AZ-FE: Aisin U241E 4‑speed automatic (FWD)
• 3.3L 3MZ‑FE: Aisin U151E 5‑speed automatic (FWD) or U151F (AWD)
• 3.3L Hybrid: Toyota HSD eCVT transaxle

Why a thrust bearing isn’t used: in manuals, a thrust/throwout bearing lets the clutch disengage. The Highlander’s autos use a torque converter and clutches inside the transaxle, and the Hybrid uses an eCVT—neither design needs a driver‑operated clutch or its thrust bearing. Any axial loads inside the engine and transmission are handled by internal thrust surfaces and washers, not by a separate, external “thrust bearing” you’d service during routine maintenance.

Worth noting: the engine itself does have crankshaft thrust faces integrated into the main bearing set to control end float, but that’s only looked at during engine overhaul work. It isn’t called out as a regular service item and isn’t replaced on its own.

If someone’s chasing a noise they’re calling a “thrust bearing” on a 2006 Highlander, it’s more likely to be one of these common culprits: the front strut top mount bearing, a noisy serpentine belt idler/tensioner, or a worn wheel hub unit bearing. Those are the bearings that actually get replaced on this model during normal servicing.

• Does a 2006 Toyota Highlander have a clutch thrust/throwout bearing?

  No. This model was built with automatic or eCVT hybrid drivetrains, so there’s no manual clutch and no release/thrust bearing to service. The transmissions used (U241E, U151E/U151F, and the Hybrid’s eCVT) rely on a torque converter or hybrid drive, not a conventional clutch.

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

  Yes, the crankshaft’s axial movement is controlled by thrust surfaces that are part of the main bearing set. It’s an internal engine component checked during rebuilds, not a routine service item. Unless there are symptoms like abnormal end float or internal engine damage, it won’t be touched.

• What usually causes a “thrust bearing” type noise on a Highlander?

  On these vehicles, front strut top mount bearings, wheel hub unit bearings, or belt idler/tensioner bearings are the usual suspects. A workshop can pinpoint the source quickly with the vehicle on a hoist and the wheels free.
