Parts for your 2001 Toyota Crown-Centre bearing

2001 Toyota Crown centre-bearing: fitted, what it does, and how to look after it

Based on technical references, the 2001 Toyota Crown (S170 series: JZS171/JZS173/JZS175, built circa 1999–2003) uses a two-piece propeller shaft with a centre support bearing. Toyota’s Electronic Parts Catalog for the S170 Crown lists a “Bearing Assy, Center Support, Propeller Shaft” for these models (commonly referenced under Toyota P/N family 37230-3xxxx), and the factory driveline section of the S170 Crown service manual details inspection and replacement of the centre support bearing. Aftermarket catalogues for Crown S170 driveline components likewise list a centre-bearing to suit these vehicles. So yes—on a 2001 Toyota Crown, a centre-bearing is relevant and fitted.

The centre-bearing’s job is to steady the long, two-piece driveshaft. It supports the shaft mid-span, keeps the angles true, and lets the rubber mount soak up harshness so the cabin stays quiet and smooth. When it’s healthy, take-off feels clean, highway cruising is steady, and there’s no odd rumble through the floor.

On an older Crown that’s done a few hundred thousand kays, the rubber can perish and the bearing can get noisy. Common tells include a thump on take-off, a shudder at 40–80 km/h, droning or rumbling that changes with road speed, and a clunk between gears. If those show up, don’t just blame the tyres—get the centre-bearing and uni joints checked.

Servicing advice for the 2001 Crown’s centre-bearing:

• Inspection: During major services or every 20,000–30,000 km, check the rubber mount for cracks, sagging, or separation. Spin the shaft by hand and feel for roughness or play in the bearing.
• Road test: Note any speed-specific vibration or load-related noises on gentle acceleration and decel.
• Replacement tips: Mark the prop shaft flanges for phasing before removal, support the shaft to avoid stressing the uni joints, and do not preload the new bearing—mount it neutral. Use new hardware if corroded and tighten to the spec in the Toyota manual.
• Afterfit checks: Recheck driveline angles, centre the support bracket, and road test for smoothness. If there’s still vibration, the shaft may need balancing and the uni joints should be assessed.

Look after the centre-bearing and the Crown keeps that trademark silky, rear-drive feel—perfect for Aussie and Kiwi roads, whether it’s the weekday commute or a long weekend run.

Popular questions about the 2001 Toyota Crown centre-bearing

How can someone tell if the centre-bearing is failing?
They’ll usually feel a shudder on take-off or around 40–80 km/h, plus a droning or rumbling that follows road speed. A torn rubber mount lets the shaft move, which can also cause a clunk on gear changes. A quick under-car check often shows cracked or sagging rubber.

If in doubt, a mechanic can raise the car safely, inspect the mount for play, and spin the shaft to feel for roughness in the bearing itself.

Can the centre-bearing be replaced without rebalancing the driveshaft?
Often yes, if the shaft is marked and reassembled in the exact same phasing and orientation. That said, if vibration was present beforehand, or if the shaft’s been split and alignment marks lost, a balance check is smart insurance.

Any persistent vibration after replacement should trigger a balance and a fresh look at uni joints and mounts.

How long does a centre-bearing typically last?
Plenty of Crowns see 150,000–250,000 km from the original. Age, heat, road grime, and torque loads all play a part. City stop–start and hard launches can shorten life, gentle highway kays tend to be kinder.

Regular inspection and prompt replacement when the rubber perishes will keep the driveline sweet and protect other components.
