Parts for your 2015 Mitsubishi Outlander-Centre bearing

2015 Mitsubishi Outlander centre-bearing: what’s fitted and what to service

Based on Mitsubishi technical material, the centre-bearing is relevant on 2015 Outlander all-wheel drive (AWD) models and not used on front-wheel drive (2WD) variants. The Mitsubishi Motors Outlander 2014–2016 Service Manual (Group 22A – Propeller Shaft) details a two-piece propeller shaft with a centre support bearing for AWD (S-AWC/4WD) models, while 2WD models have no propeller shaft at all, so no centre-bearing. The Mitsubishi ASA electronic parts catalogue for GF/GG-series Outlander (2013–2018) likewise lists a centre-bearing/bracket assembly for AWD variants.

For 2015 Outlander AWD owners, the centre-bearing is a small but crucial part of the driveline. It supports the two-piece propeller shaft that runs from the transfer unit to the rear diff, keeping the shaft aligned and stable across bumps and at highway speeds. The rubber insulator around the bearing isolates vibration so the cabin stays quiet and smooth.

When the centre-bearing starts to tire, it usually speaks up. Common signs include a low-speed shudder on take-off, a droning or humming that rises with road speed, or a thump when shifting from reverse to drive. On the hoist, technicians look for cracked rubber around the bearing, sloppy support, or play that lets the shaft move up and down more than it should.

As part of regular servicing in Australia and New Zealand conditions, it’s smart to have the prop shaft and centre-bearing visually inspected every 20,000–30,000 km or annually—especially if the vehicle tows, sees corrugations, or does long hot runs. Checks include the centre-bearing insulator for splits, the bracket for looseness, the prop shaft joints for play, and any contact marks that hint at misalignment. Any unusual vibration after tyre or suspension work is also a cue to recheck the driveline.

Replacement approach depends on parts availability and workshop practice. Mitsubishi commonly supplies the propeller shaft as a complete assembly, however, many driveline specialists can press off and replace the centre-bearing with quality aftermarket components. If replacing the bearing only, careful marking of the shaft halves is essential to preserve phasing and balance. New mounting hardware and correct torque on the bearing bracket are a must, followed by a road test under load to confirm the shudder or drone is gone.

Drivers who mostly do city kilometres may get long life from the original centre-bearing. Outlanders that tow, carry big loads, or live on rough backroads will benefit from earlier inspection. If it’s an Outlander 2WD, there’s no centre-bearing fitted, and any vibration should be chased in tyres, wheels, engine mounts, or front driveline instead.

• AWD models: centre-bearing fitted on the two-piece prop shaft.
• 2WD models: no centre-bearing (no rear prop shaft).

Popular questions

Does a 2015 Outlander 2WD have a centre-bearing?
No. The 2WD runs a transverse engine with no rear prop shaft, so there’s no centre-bearing to service or replace. Vibration on these models is usually related to tyres, wheels, suspension bushes, or engine/trans mounts.

What are the symptoms of a failing centre-bearing on an AWD Outlander?
Look for a take-off shudder, a steady-speed drone that changes with road speed, or a clunk when shifting between drive and reverse. On inspection, cracked rubber around the bearing or excess shaft movement are strong clues.

Can the centre-bearing be replaced separately from the prop shaft?
Many driveline specialists can replace the bearing and insulator on their press, but Mitsubishi often lists the prop shaft as a complete unit. If doing the bearing only, correct phasing, balance care, and re-torque of the bracket are critical to avoid new vibrations.
