Parts for your 2009 Mitsubishi Outlander-Centre bearing

2009 Mitsubishi Outlander centre-bearing — what applies and when

According to Mitsubishi workshop material for the 2007–2012 Outlander range (driveline/propeller shaft section) and OEM parts catalogues for AU/NZ, a centre support bearing is used on AWD (AWC) 2009 Outlander models because they run a two-piece rear propeller shaft. Front-wheel-drive variants don’t have a rear prop shaft at all, so a centre-bearing isn’t fitted or required on those vehicles.

For AWD owners, the centre-bearing sits midway along the two-piece prop shaft, cradled in a rubber mount and bolted to the body. Its job is to support the shaft, keep it aligned, and help control vibration as torque is sent to the rear diff. When it’s healthy, the driveline runs smooth and quiet. When it’s tired, drivers may notice a low-speed shudder on take-off, a droning or rumbling that rises with road speed, or a thump as the load comes on and off the throttle.

Servicing-wise, it’s worth asking the workshop to check the centre-bearing any time the Outlander is on a hoist. They’ll spin the shaft, feel for roughness, and look for perished rubber or excessive movement at the mount. Because the bearing lives underneath and cops heat, road grime and the odd splash, the rubber support can crack with age, even if the bearing still turns freely.

If replacement is needed, the prop shaft is removed and marked for phasing so it goes back together in the same orientation. Many techs replace the centre-bearing as an assembly on the shaft to keep balance spot-on. While they’re there, they’ll also inspect the universal joints, coupling bolts and rear diff flange, and renew any tired fasteners. Correct refit and torque helps prevent new vibrations cropping up later.

Drivers can help the bearing last by staying on top of underbody checks, keeping an ear out for fresh noises after tyre or suspension work, and sorting any vibration early before it hammers the mount. Outlanders that tow, see lots of corrugations, or run heavier loads benefit from more frequent inspections, as those conditions put extra stress through the shaft and support.

• Typical warning signs: droning or humming from the centre tunnel, shudder on launch, clunk on throttle changes, visible cracks in the support rubber.
• Good practice: inspect at regular services, keep the prop shaft correctly aligned and balanced, and address vibration before it snowballs.

For FWD 2009 Outlanders, no centre-bearing is used because there’s no rear propeller shaft, the transaxle drives the front wheels directly, so there’s nothing mid-car that needs that extra support.

Popular questions

Does my 2009 Outlander have a centre-bearing?
If it’s AWD (AWC), yes — it uses a two-piece rear prop shaft with a centre support bearing. If it’s FWD, there’s no rear prop shaft, so no centre-bearing is fitted. A quick look under the car for a shaft running to the rear diff will tell the story.

What are the signs a centre-bearing needs attention?
Common clues include a droning or humming that changes with speed, a shudder on take-off, or a clunk when getting on and off the throttle. Underneath, the rubber mount may look cracked or the shaft may have too much play at the support.

Can it be replaced separately, or is a full shaft needed?
On many AWD Outlanders the centre-bearing can be replaced on the existing shaft, but shops often prefer to do it as an assembly and then balance the shaft to keep vibrations away. A technician will advise based on condition and parts availability.
