Parts for your 2017 Mitsubishi Outlander-Centre bearing

2017 Mitsubishi Outlander centre-bearing: what it does and when it matters

Referencing technical sources used in workshops — specifically the Mitsubishi Motors Service Manual for the 2017 Outlander (propeller shaft/driveline section) and the Mitsubishi ASA electronic parts catalogue — confirms that a centre support bearing is fitted on 2017 Outlander models equipped with all-wheel drive (AWD/AWC or S-AWC). Front-wheel-drive (2WD) variants don’t have a propeller shaft to the rear, so a centre-bearing isn’t used or relevant on those models. The OEM catalogues typically show the centre-bearing as part of the complete propeller shaft assembly rather than a separate service part.

Because the AWD 2017 Outlander is fitted with a centre-bearing, here’s what that part does and how to look after it. The centre-bearing supports the two-piece propeller shaft that runs down the middle of the vehicle from the transaxle to the rear differential. Its rubber-mounted support isolates vibration and keeps the shaft aligned under load. When it’s healthy, the driveline feels smooth and quiet on take-off, cruising and when towing. When it starts to go, owners often notice a droning or humming that rises with road speed, a shudder under acceleration, or a clunk as drive takes up.

• Common symptoms: vibration on take-off, booming/hum at 40–80 km/h, clunking when shifting between reverse and drive, and visible cracking or sag in the rubber support.
• Quick checks: inspect the rubber carrier for splits, check the bearing play, look for torn prop shaft boots, and ensure the support bracket and heat shields are tight.

Servicing is straightforward but precise. On many 2017 Outlanders the centre-bearing isn’t supplied by Mitsubishi as an individual part, so workshops typically replace the complete propeller shaft assembly. Aftermarket bearings do exist, fitting them requires pressing the old bearing off, installing the new one correctly, and then ensuring the shaft remains in phase and balanced — otherwise new vibrations can appear. Mark prop shaft positions before removal, torque fasteners to the factory spec, and use new bolts or thread locker where the manual calls for it. Once fitted, a short road test across different speeds will confirm the fix.

There’s no scheduled maintenance for the centre-bearing, but at service time it’s smart to have the tech check the support rubber, shaft joints, rear diff mounts and exhaust clearances. If the Outlander tows, carries a full load often, or has clocked up plenty of kilometres on coarse-chip roads, a more frequent underbody inspection pays off. Catching a tired centre-bearing early avoids collateral wear on joints and mounts, and keeps the AWD system feeling tight and tidy.

Popular questions about the 2017 Mitsubishi Outlander centre-bearing

Does my 2017 Mitsubishi Outlander have a centre-bearing?
AWD models do, because they use a two-piece propeller shaft to drive the rear wheels. Front-wheel-drive models don’t have a prop shaft, so there’s no centre-bearing fitted. A quick look underneath for a long shaft down the tunnel is the easy tell.

If your badge or build plate shows AWD/AWC (or S-AWC on some trims), it’s the variant that uses the centre support bearing.

Can I replace just the centre-bearing, or do I need a whole prop shaft?
From the factory, the bearing is usually part of the complete propeller shaft assembly. Many workshops replace the assembly for best results. Aftermarket bearings are available, but pressing one on and keeping the shaft correctly phased and balanced is critical.

If going the bearing-only route, choose quality parts and a shop experienced with driveline work to avoid fresh vibrations.

What noises point to a failing centre-bearing on an Outlander?
Think low-speed shudder on take-off, a droning or booming that tracks road speed, and a dull clunk as drive takes up. These can overlap with tyre or wheel bearing noises, so a proper inspection of the prop shaft support and joints is the way to nail it.

Any visible cracks in the rubber carrier or looseness in the bearing are a sign it’s time to act.
