Parts for your 2017 Toyota Rav4-Centre bearing

2017 Toyota RAV4 centre-bearing — what’s fitted and when

Based on technical sources, a centre-bearing is only relevant to 2017 Toyota RAV4 models with AWD. Front-wheel-drive (2WD) RAV4s don’t have a propeller shaft running to the rear, so there’s no centre-bearing to service or replace. This is supported by Toyota’s 2016–2018 (XA40) RAV4 Repair Manual (Drivetrain/Axle – Propeller Shaft) which details a two-piece propeller shaft with a centre support bearing for AWD variants, and by the Toyota Electronic Parts Catalogue (EPC) for 2017 RAV4 AWD (e.g., ASA44), which lists a “Bearing Assy, Centre Support” as part of the prop shaft assembly. Major aftermarket catalogues also list a drive shaft centre support bearing specifically for 2013–2018 RAV4 AWD models, and not for 2WD models.

For the 2017 RAV4 AWD, the centre-bearing (also called the centre support bearing) sits midway along the two-piece propeller shaft. Its job is to support the shaft, keep it aligned under load, and soak up vibration so the cabin stays quiet and the driveline stays smooth. In normal operation it’s a sealed bearing housed in a rubber isolator that bolts to the vehicle’s underbody. There’s nothing to lubricate, but it does need a periodic look during routine servicing.

Good practice is to visually inspect the centre-bearing at each service or at least every 20,000 km when the vehicle’s on a hoist. The technician should check the rubber carrier for cracks or separation, spin the shaft to feel for roughness, and look for excessive play or sag at the support. Typical warning signs include:

• A low-speed shudder on take-off or under load
• A humming or droning vibration between about 40–80 km/h that changes with throttle
• A clunk on select between reverse and drive
• Visible tearing of the rubber isolator or off-centre alignment

When replacement is needed, most workshops remove the entire propeller shaft, mark flange positions to preserve phasing and balance, and either press off and replace the centre-bearing or fit a complete new/reconditioned prop shaft if the bearing is integral. On reassembly, it’s important to:

1. Align the yokes exactly as marked to prevent new vibrations
2. Tighten the centre support bracket with the vehicle at normal ride height so the rubber isn’t preloaded
3. Torque all fasteners to spec from the Toyota repair manual and verify driveline angles

Because the bearing is sealed, contamination and heat are its main enemies. Worn engine or gearbox mounts can accelerate failure by changing driveline angles, so it’s smart to have mounts checked if a new vibration appears. If a persistent NVH issue remains after bearing replacement, a shaft balance or full prop shaft assembly may be the cleaner fix. None of this applies to 2WD RAV4s, which don’t run a rear prop shaft and therefore don’t have a centre-bearing to worry about.

FAQs

Do all 2017 RAV4s have a centre-bearing?
No. Only AWD (all-wheel-drive) variants have a two-piece prop shaft with a centre support bearing. Front-wheel-drive models don’t have a prop shaft to the rear, so there’s no centre-bearing fitted.

What are the signs a centre-bearing is failing on a 2017 RAV4 AWD?
Common symptoms include a low-speed shudder on take-off, a humming or droning vibration that’s speed- or load-dependent, a clunk when shifting between drive and reverse, and visible cracking or sagging of the rubber support.

Can the centre-bearing be replaced on its own, or does the whole shaft need changing?
Many workshops can replace just the centre-bearing if the prop shaft design and condition allow. However, some prefer a complete prop shaft assembly to ensure balance and longevity. Toyota often supplies the bearing as part of the prop shaft assembly, aftermarket bearings may be available separately.
