Parts for your 1999 Toyota Crown-Centre bearing

1999 Toyota Crown centre-bearing: fitted, what it does, and when to replace it

Based on technical sources, the 1999 Toyota Crown uses a centre-bearing. The Toyota Electronic Parts Catalogue (Japan domestic market) lists a “Bearing Assy, Centre Support, Propeller Shaft” (group 37230) for S170-series Crown models built 1999–2003, including JZS171/JZS173/GS171/LS171. The Toyota Crown S170 Repair Manual (Propeller Shaft section) also specifies a two-piece tailshaft with a centre support bearing. That makes the centre-bearing relevant on the 1999 Toyota Crown.

On the S170 Crown, the centre-bearing supports the long, two-piece tailshaft that runs from the transmission to the diff. Splitting the shaft and adding a rubber-isolated bearing keeps vibrations in check, reduces driveline shudder, and helps the shaft run below its critical speed. It’s a quiet achiever: when the rubber support or bearing wears out, owners usually notice a rumble that rises with road speed, a shudder on take-off, or a thud when shifting from Drive to Reverse.

As part of servicing, a visual check is worth doing every 20,000–40,000 km, especially on higher-kilometre Crowns. Look for cracked or perished rubber in the bearing carrier, misalignment, or excessive movement when the shaft is levered by hand. The bearing itself is sealed and not serviceable, if it’s noisy or the carrier is torn, replacement is the fix.

Replacement is a straightforward workshop job but it’s fussy about alignment. A tech will mark the tailshaft phasing, remove the two halves, press off the old bearing, then press on a quality replacement and refit the carrier. It’s smart to check universal joints at the same time and renew any worn mounts that can throw angles out. Correct phasing of the shaft, proper carrier height/shimming, and factory torque specs are essential to avoid fresh vibrations. Balancing isn’t always required, but if the shaft’s been apart before or weights are missing, a balance is cheap insurance.

For most owners, the cue to act is driveline noise or shudder. Ignored, a collapsing carrier can stress U-joints and the transmission mount. Genuine or reputable aftermarket bearings both work well, choose by VIN to suit the exact S170 variant. Two-wheel-drive S170 sedans and estates typically share the centre-support design, while some driveline variants differ, so a quick parts-check is wise.

Does a 1999 Toyota Crown have a centre-bearing?

Yes. The S170-series Crown (1999–2003) runs a two-piece tailshaft with a centre support bearing, as shown in Toyota’s EPC and the S170 Repair Manual.

What are the signs the centre-bearing is failing on a 1999 Crown?

Common giveaways are a low rumble that increases with speed, a shudder on take-off, and a clunk when selecting Drive or Reverse. A torn carrier rubber or visible shaft misalignment on inspection also points to replacement time.

How long does replacement take, and is balancing or an alignment needed?

Allow around 1.5–3 hours in a workshop. Wheel alignment isn’t involved, but tailshaft phasing and carrier height must be set correctly. Balancing is only needed if there’s a persistent vibration or prior damage/weight loss on the shaft.
