Parts for your 2000 Toyota Crown-Centre bearing

2000 Toyota Crown centre-bearing: what it does and how to look after it

Technical sources confirm the 2000 Toyota Crown (S170 series: JZS171/JZS173/JZS175) is built with a two-piece propeller shaft that uses a centre support bearing (often called a centre-bearing). The Toyota Electronic Parts Catalogue for S170 Crown lists “Bearing, Centre Support, Propeller Shaft” for these models, with common OE part numbers including 37230-30070 and 37230-30080 (varies by VIN). The Toyota Factory Repair Manual for the S170 drivetrain also shows inspection and replacement procedures for the centre support bearing and bracket in the Propeller Shaft section. That makes the centre-bearing a relevant, fitted component on the 2000 Toyota Crown.

In everyday terms, this bearing sits mid-way along the Crown’s two-piece tailshaft, holding it steady, keeping alignment true, and soaking up vibration through a rubber isolator. That’s why a healthy centre-bearing is a big part of the Crown’s smooth, quiet cruising.

As part of routine servicing, it pays to inspect the centre-bearing every 20,000–30,000 kilometres or whenever there’s a driveline noise complaint. Look for perished or torn rubber, a sagging support, roughness when the shaft is rotated by hand, or any free play at the bearing. On the road, tell-tale signs include:

• A low hum or drone between about 40–80 km/h that’s worse on throttle and eases when coasting
• Shudder on take-off or under load
• A dull clunk as drive takes up
• Persistent vibration that isn’t tyre- or wheel-related

Replacement is straightforward for a driveline specialist. The shaft is removed, alignment marks are made on the flanges, the centre support bracket is unbolted, and the old bearing is pressed off and a new one pressed on. It’s vital to maintain the original phasing and balance of the two shaft halves, misalignment can cause fresh vibration. Always follow factory torque specs, replace any fatigued hardware and dust seals, and check the transmission mount and differential bushings while you’re there.

On these Crowns, universal joints are often staked from factory, so if a U-joint is also worn, the shop may recommend a complete tailshaft rebuild or exchange unit. Using a quality OE or reputable aftermarket centre-bearing pays off in longevity and NVH. With a fresh centre-bearing, the Crown feels planted, quiet and properly refined again.

Does the 2000 Toyota Crown have a centre-bearing?

Yes. The S170-series Crown runs a two-piece propeller shaft with a centre support bearing. This is documented in Toyota’s Factory Repair Manual (Propeller Shaft section) and the Toyota EPC, which lists the “Bearing, Centre Support, Propeller Shaft” for 1999–2003 Crown models under part numbers such as 37230-30070/30080.

What symptoms point to a failing centre-bearing on a 2000 Crown?

Common signs are a humming or droning noise that peaks around suburban speeds, shudder on take-off, a clunk as drive engages, and a steady vibration that improves when coasting. Visual checks may show cracked rubber, a sagging bracket, or noticeable play in the bearing.

Is the centre-bearing serviceable or does it need full replacement?

The bearing itself isn’t serviceable, it’s replaced as an assembly with the support. During the job, the technician will mark the shaft for phasing, press off the old unit, fit the new bearing, and reassemble to factory torque. It’s also smart to inspect U-joints, the slip yoke spline, and mounts at the same time.
