Parts for your 2006 Toyota Caldina-Thrust bearing

2006 Toyota Caldina thrust-bearing — is it actually a thing on this model?

For the 2006 Toyota Caldina (T240-series), a traditional clutch thrust-bearing (also called a release or throw-out bearing) isn’t used on the vast majority of vehicles because they were built with electronically controlled automatic transaxles and a torque converter, not a manual clutch. That means there’s no external clutch release mechanism or thrust-bearing to service or replace on typical 2006 Caldinas imported to Australia and New Zealand.

This call is backed by technical references. Toyota’s Electronic Parts Catalogue (EPC) listings for the 2006 Caldina model codes (including the well-known ST246 GT-Four and mainstream ZZT/AZT variants) show automatic transaxles and do not list a clutch release/thrust-bearing assembly for those builds. Toyota’s New Car Features (NCF) documentation for the Caldina ST246 also describes a torque-converter automatic (Super ECT) with no clutch pedal or release mechanism. Toyota automatic transaxle overhaul manuals detail internal thrust washers and needle bearings inside the gearbox, but these aren’t the same thing as a clutch thrust-bearing and aren’t routine service items.

Why it’s not used: with a torque converter doing the coupling between engine and gearbox, the drivetrain has no pressure plate or release fork. The auto trans does all the work hydraulically and electronically, so there’s nothing for a driver-operated thrust-bearing to press against. Any “thrust” components inside the automatic are internal support bearings and washers for gearsets and shafts, handled only during a transmission rebuild, not regular servicing.

Edge case worth noting: a handful of early T240-series Caldina grades in Japan were available with a manual gearbox. If someone does have a genuine 2006 manual Caldina (rare in AU/NZ), it will use a clutch release/thrust-bearing. Easiest way to confirm at a glance is the gear selector: PRND for autos, H-pattern for manuals. The transmission ID plate or build sheet will also make it clear.

Practical tip for owners: If an automatic Caldina is making noises some people associate with a “bad thrust-bearing” (whirring when idling, noise changing with A/C on, etc.), it’s more likely to be the serpentine belt idler/tensioner, the A/C clutch pulley, or normal torque converter/ATF pump sounds. Fresh genuine-spec ATF, correct idle speed, and a check of the belt drive usually sorts most complaints without any gearbox drama.

FAQs

Does a 2006 Toyota Caldina have a clutch thrust-bearing?
Most 2006 Caldinas are automatic and don’t have a clutch thrust-bearing at all. If it’s a very rare manual version, then yes, the clutch assembly includes a release/thrust-bearing. Check the gear selector or the transmission code on the vehicle ID plate to be sure.

What noises can sound like a bad thrust-bearing on an automatic Caldina?
On autos, common culprits are the serpentine belt idler or tensioner, the A/C compressor clutch pulley, or light torque-converter/ATF pump whine. These are normal service items or characteristics and don’t involve a clutch bearing.

Does the Caldina engine have a crankshaft thrust bearing?
Yes, the engine has thrust surfaces as part of the main bearings to control end float, but they’re internal and not a routine service item. They’re only inspected during an engine rebuild or if there’s a specific fault.
