Parts for your 2017 Toyota Crown-Centre bearing

2017 Toyota Crown centre-bearing: what it does and how to look after it

Based on Toyota’s technical literature for the S210-series Crown (propeller shaft section of the Toyota Repair Manual) and the Toyota Electronic Parts Catalogue under Propeller Shaft & Universal Joint, the 2017 Toyota Crown is built with a two-piece propeller shaft that uses a centre support bearing (often called a centre-bearing). This applies to the rear-wheel drive models and AWD variants that still employ a multi-piece rear prop shaft. So yes — a centre-bearing is fitted on the 2017 Crown.

The centre-bearing’s job is to support the two-piece prop shaft mid-span, keeping it aligned and stable as torque runs from the transmission to the rear differential. By holding the shaft in place and cushioning it with a rubber isolator, the bearing helps cut down on vibration, driveline shudder, and noise at cruising speeds and under load. On a long-wheelbase sedan like the Crown, a centre-bearing also lets Toyota run a lighter, better-balanced two-piece shaft rather than a single long tube.

As part of regular servicing, a quick eyes-on check of the centre-bearing is a smart move, especially if the car does lots of motorway kilometres or tows. Look for perished or cracked rubber in the support, signs of the bearing running rough, or any evidence the bracket is loose or distorted. Many workshops give it a look-over at each service, owners who hear new vibrations may want it checked straight away rather than waiting for the next interval.

• Common symptoms of wear: vibration on take-off or under load, a droning or humming at mid–high speeds, a thunk/clunk when selecting drive or moving off, and visible sagging, tears, or play at the support.
• Best practice on replacement: mark the prop shaft orientation before removal to preserve balance, use new hardware where specified, and torque to Toyota specs. If the universal joints are staked (common on some Toyota shafts), a driveline specialist may be needed to press and rebalance the assembly.

Most 2017 Crown centre-bearings can be replaced as a service part (Toyota labels it Bearing Assy, Centre Support). Given how sensitive the Crown’s driveline is to balance, professional installation and a balance check of the prop shaft are good insurance against repeat vibrations. After refit, a road test across different speeds and light/heavy throttle helps confirm the fix.

Popular questions about 2017 Toyota Crown centre-bearing

Does the 2017 Toyota Crown actually have a centre-bearing?
Yes. Toyota’s S210 Crown documentation and parts listings show a two-piece propeller shaft with a centre support bearing. It’s there to steady the shaft, reduce vibration and noise, and handle the length of the driveline in this rear-drive platform.

What symptoms point to a worn centre-bearing on a 2017 Crown?
Typical giveaways are a shudder on take-off, a droning or humming that changes with road speed (not engine rpm), and a thud when selecting drive. A quick underbody check often reveals cracked or sagged rubber around the support, or noticeable play in the shaft at the bracket.

Can the centre-bearing be replaced on its own, or is a whole new prop shaft needed?
On many Crowns the centre-bearing is available as a separate assembly. However, because some Toyota prop shafts use staked universal joints, removal and refit can call for specialist tooling and rebalancing. If the U-joints are worn or the shaft is out of balance, a rebuilt or replacement shaft may be the smarter route.
