Parts for your 2016 Toyota Rav4-Centre bearing

2016 Toyota RAV4 centre-bearing: is it used and does it matter?

Technical sources show a centre-bearing is relevant on AWD versions of the 2016 Toyota RAV4, but not on 2WD models. The Toyota RAV4 (XA40, 2013–2018) Repair Manual includes a two-piece propeller shaft with a centre support bearing and bracket for AWD variants. The Toyota Electronic Parts Catalogue (EPC) likewise lists a “Bearing Assy, Centre Support” for AWD model codes (e.g., ASA44, ALA49), while 2WD models (e.g., ASA42, ZSA42) have no propeller shaft and therefore no centre-bearing.

For owners of AWD 2016 RAV4s, the centre-bearing does an important job. It supports the middle of the two-piece prop shaft running from the transfer case to the rear differential, keeping the shaft aligned and helping soak up vibration through a rubber-mounted carrier. When it’s healthy, driveline noise is minimal and the car feels smooth on take-off and at highway speeds.

There’s no greasing or periodic lubrication needed—the bearing is sealed—but it should be visually checked during regular servicing. A tech will look for perished or cracked rubber in the carrier, excessive shaft play at the bearing, and any signs of the bearing running rough. Common warning signs include:

• A humming or droning between about 40–80 km/h that changes with speed
• Shudder or vibration on acceleration, especially from a standstill
• A dull clunk when selecting Drive/Reverse, or lift-off/on-throttle lash

If those symptoms appear, it’s smart to have the centre-bearing assessed promptly. Driving long-term with a failed bearing can stress the prop shaft joints, transfer case and rear diff mounts.

Replacement involves removing the prop shaft assembly, marking the flanges so it goes back in the same orientation, unbolting the centre support bracket, and pressing off the old bearing. The new bearing is pressed on in the correct direction, the carrier is reinstalled, and the bracket fasteners are torqued to spec before a road test. Many workshops will also check prop shaft balance and the condition of the universal joints at the same time. While the bearing can be replaced on its own, if there’s noticeable U-joint wear or imbalance, some shops may recommend a complete prop shaft assembly to ensure long-term smoothness.

Practical tips:

• Ask your mechanic to inspect the carrier rubber at each service, especially if the vehicle tows or sees corrugated roads.
• If chasing a vibration, rule out tyres and wheels first, then check engine/trans mounts, before zeroing in on the centre-bearing.
• After any bearing replacement, a short follow-up check for fastener torque and leaks is good practice.

FAQs

Does every 2016 RAV4 have a centre-bearing?
No. Only AWD models have a two-piece prop shaft and a centre-bearing. Front-wheel-drive (2WD) RAV4s don’t have a prop shaft to the rear, so there’s no centre-bearing to service. A quick look underneath: if there’s a shaft running down the centre tunnel to the rear diff, it’s AWD and has a centre-bearing.

How long should a centre-bearing last on a 2016 RAV4?
Many last well past 150,000 km, but life varies with age, road conditions, towing and exposure to heat. The rubber carrier can harden and crack over time, and the bearing can get noisy as it wears. Routine inspections during servicing help catch issues early.

Can the centre-bearing be replaced separately, or is a full prop shaft needed?
The centre-bearing and carrier can usually be replaced on their own. However, if there’s noticeable play in the universal joints or evidence of imbalance, some workshops may recommend replacing or reconditioning the complete prop shaft to restore smooth driveline operation.
