Parts for your 2008 Mitsubishi Outlander-Centre bearing

2008 Mitsubishi Outlander centre-bearing

Based on technical references, a centre-bearing is used on 2008 Mitsubishi Outlander models equipped with AWD/AWC. The Mitsubishi Motors Outlander 2007–2012 Workshop Manual (Group 22A: Propeller Shaft) illustrates a two-piece propeller shaft with a centre support (carrier) bearing on 4WD models. The Mitsubishi ASA Electronic Parts Catalogue for CW5W/CW6W 4WD similarly lists a propeller shaft centre bearing, and AU/NZ trade catalogues commonly list centre support bearings for 2007–2013 Outlander AWD. Front-wheel-drive Outlanders have no rear propeller shaft, so a centre-bearing isn’t fitted on those variants.

On AWD Outlanders, the centre-bearing’s job is to support the two-piece prop shaft between the transfer case and the rear diff, keeping it running true and quiet. That rubber-isolated bearing soaks up vibration, keeps driveline angles happy, and helps the Outlander feel smooth at highway speeds.

When it starts to go, owners often notice a low-frequency drone or hum that rises with road speed, a shudder under load, or a clunk on take-off as the shaft moves around more than it should. Leaving it too long risks extra wear on the prop shaft joints and mounts.

Servicing-wise, it’s worth a look any time the Outlander is on a hoist for AWD maintenance. A quick spin and shake test of the prop shaft at the centre support will reveal excess play, torn rubber, or roughness. While Mitsubishi often supplies the prop shaft as a complete assembly, reputable aftermarket centre support bearings are available locally. Replacing the bearing alone needs a press, correct support of the shaft, and care to keep the shaft halves in phase—always mark their relative positions before separation to preserve balance.

Good practice during replacement includes:

• Inspecting prop shaft joints and boots for play or splits while the shaft is out.
• Renewing any tired mounts and using fresh hardware or threadlocker where specified.
• Torquing the centre support bracket and flange bolts to workshop manual specs.
• Road testing for vibration and rechecking fasteners after a short run.

For most Aussie and Kiwi drivers, a centre-bearing can last well beyond 150,000 km, but vehicles doing lots of towing, gravel, or beach work may see earlier wear. Keeping the underbody clean and addressing any driveline vibration early will help the bearing live a longer, quieter life.

Popular questions

Do all 2008 Outlanders have a centre-bearing?
No. Only AWD/AWC models have a two-piece prop shaft with a centre support bearing. Front-wheel-drive models don’t have a rear prop shaft, so there’s no centre-bearing fitted.

What are common signs the centre-bearing is failing?
A growl or drone that follows road speed, a shudder on acceleration, and a clunk on take-off are the big giveaways. Visual checks may show torn rubber around the carrier or excessive movement when the shaft is pushed up and down.

Can the centre-bearing be replaced separately, or is a full prop shaft needed?
Many workshops replace just the centre support bearing with quality aftermarket parts, provided the shaft is marked, pressed apart and reassembled correctly to maintain balance and phasing. Some prefer a complete shaft assembly for simplicity and warranty, especially if the joints are also worn.
