Parts for your 2018 Toyota Crown-Centre bearing

2018 Toyota Crown centre-bearing: what it is and why it matters

Based on Toyota’s technical literature and parts catalogues, the 2018 Toyota Crown (S220 series, FR layout) uses a two-piece propeller shaft with a centre support bearing. Toyota’s Repair Manual for the S220 Crown details a propeller shaft assembly with a centre support bracket/bearing, and Toyota’s Electronic Parts Catalogue lists a “Bearing Assy, Center Support, Propeller Shaft” under the driveline group for this model. Aftermarket catalogues for the 2018-on Crown also cross-list centre support bearings, confirming the part is fitted and serviceable.

On the 2018 Toyota Crown, the centre-bearing’s job is to support the long, two-piece prop shaft that runs from the transmission to the rear diff. By holding the shaft steady mid-length, it keeps driveline angles in check, cuts vibration and noise, and helps the universal joints live a longer, happier life. It’s a sealed bearing mounted in a rubber cushion and bracket, so it deals with both rotation and movement as the driveline flexes over bumps and under load.

As part of sensible servicing, the centre-bearing and its rubber support are worth a look any time the car’s on a hoist. There’s no greasing point (it’s sealed), but techs should check for perished or torn rubber, any sag in the mount, and play or roughness when the shaft is rotated by hand. If the bearing or its support starts to go, the Crown will often tell on take-off with a shudder, a low-speed drone or hum that changes with road speed, or a clunk when selecting drive.

• Common signs it’s had enough:
  • Shudder under load or on gentle take-off
  • Droning/whirring from mid-car that rises with speed
  • Visible cracks or separation in the rubber carrier

Replacement is straightforward for a trained tech: mark the prop shaft orientations to preserve balance, drop the centre bracket, split the shaft, and press the old bearing off. The new bearing must be pressed on square, with correct orientation and dust shield placement, then the bracket torqued to spec and the shaft refitted to the same alignment marks. If previous marks are missing or vibration was present, a balance check is smart. Using OE or high-quality aftermarket bearings saves headaches, and it’s wise to inspect the uni joints and guibo (if fitted) while you’re there. After the job, a road test to verify smooth take-off and cruise is a must. Looked after properly, a centre-bearing on a well-kept Crown will usually last a long time, but age, heat and mileage eventually take their toll on the rubber support.

• Tips:
  • Inspect every service at hoist height
  • Replace at the first signs of rubber separation or bearing roughness
  • Keep heat shields intact to protect the rubber carrier

Popular questions about 2018 Toyota Crown centre-bearings

What are the tell-tale symptoms of a worn centre-bearing on a 2018 Crown?
A rumbling or droning from beneath the centre of the car that changes with road speed is a classic sign. Many owners also notice a shudder on take-off or a thud when selecting drive or reverse. On the hoist, cracked or sagging rubber around the bearing is a giveaway.

How long does a centre-bearing typically last?
There’s no set interval, but on a well-maintained Crown they often run well past 150,000 km. High heat, rough roads, hard launches and fluid contamination can shorten life, mainly by degrading the rubber support rather than the sealed bearing itself.

Is it safe to keep driving with a noisy centre-bearing?
Short term, it may still be drivable, but it’s not a great idea. As the rubber carrier fails, driveline angles go off and vibration increases, which can accelerate wear in the uni joints and transmission mount. Sorting it early is cheaper and keeps the drive smooth.
