Parts for your 2016 Toyota Mark x-Centre bearing

2016 Toyota Mark X centre-bearing: what it is, why it matters, and when to service it

Based on Toyota’s technical literature for the GRX130/GRX133 series (2012–2019), including the Propeller Shaft section of the Toyota Repair Manual and the Toyota Electronic Parts Catalogue for 2016 Mark X variants, this vehicle uses a rear-wheel drive layout with a two-piece propeller shaft and a centre support bearing (often called a centre-bearing). These sources list a “Bearing Assy, Centre Support, Propeller Shaft” for the Mark X, and the workshop diagrams show the two-piece shaft with the bearing mounted to the body tunnel.

On the 2016 Toyota Mark X, the centre-bearing supports the two-piece prop shaft between the transmission and the rear differential. Its job is to keep the shaft aligned under load, manage driveline angles, and isolate noise and vibration. The bearing sits in a rubber cushion that absorbs movement so the cabin stays quiet and the driveline runs smoothly at highway speeds.

Over time, the rubber support can perish and the bearing can wear. Common signs include a dull thump on take-off, a droning or humming that rises with road speed, and shudder under acceleration. Left too long, excess movement can stress the universal joints and even affect differential and transmission mounts.

As part of regular servicing, it’s smart to have the centre-bearing visually checked every 20,000–30,000 km or during any underbody inspection. Look for cracked or separated rubber, rusty dust around the bearing, or noticeable play in the prop shaft near the support.

• If wear is found, replace the centre-bearing assembly and inspect the universal joints at the same time.
• Mark flange positions before removal to maintain balance, and refit with the vehicle at normal ride height to avoid preloading the mount.
• Use quality parts and have the shaft balance checked if any vibration persists after replacement.
• After installation, road test across 50–110 km/h to confirm NVH is sorted.

There’s no fixed replacement interval—condition and use matter most. Vehicles that frequently tow, sit on corrugated roads, or clock big motorway kilometres may need attention earlier. A healthy centre-bearing keeps the Mark X feeling tight and refined, just as it should.

Popular questions about 2016 Toyota Mark X centre-bearing

Does the 2016 Mark X actually have a centre-bearing?
Yes. The GRX130/GRX133 Mark X uses a two-piece propeller shaft with a centre support bearing, as shown in Toyota’s Repair Manual (Propeller Shaft section) and the Toyota Electronic Parts Catalogue for 2016 models.

What symptoms point to a failing centre-bearing on a Mark X?
Owners often notice a low-frequency hum or drone that changes with speed, a shudder on take-off, or a clunk when shifting from reverse to drive. Visual checks may reveal cracked rubber around the support or excess shaft movement at the bearing.

When should a Mark X centre-bearing be replaced?
There’s no strict kilometre limit. Replace it when there’s play, noise, or perished rubber. It’s sensible to inspect it during scheduled services and definitely whenever addressing driveline vibrations or universal joint repairs.
