Parts for your 2007 Toyota Crown-Thrust bearing

2007 Toyota Crown thrust-bearing: what it is, where it lives, and how to look after it

From Toyota’s technical literature for the S180-series Crown (New Car Features for the Aisin 6‑speed automatics, the GR‑series Engine Repair Manual, and the Toyota Electronic Parts Catalog), this model is fitted with an automatic transmission and does not use a clutch release/“thrust” bearing. However, its GR‑series V6 engines do use crankshaft thrust bearings (thrust faces integrated into the main bearing set) to control axial crank movement. So “thrust bearing” is very much relevant on a 2007 Toyota Crown—just in the engine, not the gearbox.

On the 3GR‑FSE or 2GR‑FSE, the thrust bearing’s job is to keep the crankshaft from walking fore‑and‑aft under axial loads from the torque converter, accessory belt forces and transient loads during shifting. By controlling endplay, it protects the block, maintains correct alignment with the rear main seal and flexplate, and helps the engine’s sensors and timing hardware stay happy. The thrust faces are pressure‑fed by engine oil, so good lubrication is everything.

It isn’t a routine service item, but it’s worth a check when chasing driveline noises or during bottom‑end work. Typical warning signs owners or techs might notice include:

• Noticeable in‑out movement of the crank pulley under a gentle pry.
• Rubbing or tinkling noises near the bellhousing (flexplate contact).
• Inconsistent idle or stalling when selecting Drive, plus metal in the oil.

Diagnosis is straightforward for a workshop: measure crankshaft endplay with a dial indicator and compare to the spec in the Toyota Engine Repair Manual (Crankshaft—Inspection). If it’s beyond limit, the engine needs attention. Replacement happens with the sump off and the relevant main bearing cap removed (the thrust faces are typically part of the centre main). Good practice is to:

• Inspect crank thrust surfaces for scoring, polish or grind only within spec.
• Fit quality main bearings to the correct size, verify clearances with Plastigage, and torque fasteners to Toyota spec.
• Use assembly lube, ensure oilways are clean, and confirm endplay after torque.

For day‑to‑day care, the best “maintenance” is clean oil of the correct grade at sensible intervals, using quality filters. Avoid transmission misalignment or forced assembly that can shove the converter into the crank. If the vehicle has had bellhousing, flexplate, or converter work, it’s smart to re‑check endplay. Following Toyota’s procedures in the GR‑series Engine Repair Manual keeps the Crown’s bottom end reliable for the long haul.

Popular questions about 2007 Toyota Crown thrust-bearing

Does a 2007 Toyota Crown have a clutch thrust/release bearing?
No. The S180‑series Crown sold in 2007 is equipped with Aisin 6‑speed automatics, which use a torque converter rather than a manual clutch. There’s no clutch release bearing. The relevant thrust bearing on this car is the engine’s crankshaft thrust bearing integrated into the main bearing set.

How can someone tell if the crankshaft thrust bearing is worn on a 2007 Crown?
Look for fore‑and‑aft movement of the crank pulley, odd bellhousing noises, or stalling when engaging Drive. A workshop can confirm by measuring crank endplay with a dial indicator and comparing to the spec in Toyota’s GR‑series Engine Repair Manual.

When should the thrust bearing be replaced on a 2007 Toyota Crown?
It’s only replaced if endplay is out of spec or during an engine rebuild. It isn’t a scheduled service item. If replacement is needed, it’s done with the sump and main caps off, following Toyota procedures, and often paired with inspection of the crank, flexplate and converter fitment.
