Parts for your 2020 Mitsubishi Outlander-Centre bearing

2020 Mitsubishi Outlander centre-bearing: fitted or not, and what to do about it

Based on the Mitsubishi Motors Outlander ZL/ZN (MY2015–2021) workshop manual propeller shaft section and the Mitsubishi ASA electronic parts catalogue, a centre-bearing (centre support bearing) is used on 2020 Outlander models that have a mechanical all-wheel drive propeller shaft. That’s the petrol AWD/i-AWC variants with a two-piece prop shaft running to the rear diff. It is not used on front-wheel drive-only petrol models, and it is not used on the Outlander PHEV, which drives the rear wheels electrically and has no prop shaft. Independent repair databases (e.g., AllData/Mitchell1) reflect the same arrangement. Always confirm by VIN if unsure.

For AWD petrol models where a centre-bearing is fitted, the part’s job is to support the two-piece propeller shaft halfway down the car, keeping driveline angles tidy and vibrations in check. The rubber-mounted bracket isolates noise and harshness, while the sealed bearing lets the shaft spin freely at highway speeds. When it’s healthy, most drivers never notice it’s there, when it’s tired, they’ll often feel a droning or a shudder under load, especially around 40–80 km/h.

It’s not a scheduled replacement item, but it should be checked at regular services. A quick visual once-over for perished rubber, tears in the support, or signs of the bearing running rough is worth doing, particularly if the vehicle tows, sees corrugated roads, or has high kilometres. Listen for a rumble that rises with road speed (not engine rpm), and watch for vibration on take-off. Also make sure mounts and prop shaft CV/universal joints aren’t the real culprits.

When replacement is due, the prop shaft comes out as an assembly. Mark the flanges so it goes back in the same orientation, keep the shaft “in phase,” and refit with new self-locking hardware where specified. Some Outlanders allow the centre-bearing assembly to be replaced on the shaft, others are serviced as a complete prop shaft—parts availability varies between OEM and aftermarket, so check by VIN. If the shaft is split for the job, it may need rebalancing. Typical workshop time is moderate, and a careful test drive is essential to confirm any vibration is gone. The bearing is sealed, so there’s no greasing—just clean installation, correct torque, and proper bracket alignment. While under there, it’s smart to eyeball heat shields, driveline boots, and transfer/diff seals for leaks.

• Key symptoms: droning/rumble with road speed, take-off shudder, visible rubber tearing, play at the support.
• Best practice: inspect at service, replace as an assembly if worn, verify parts by VIN, road-test after fitment.

Popular questions

Does a 2020 Outlander 2WD or PHEV have a centre-bearing?
No. The 2WD petrol has no rear prop shaft, and the PHEV drives the rear wheels via an electric motor, so neither uses a centre-bearing. Only the petrol AWD/i-AWC models with a two-piece prop shaft have one.

How do they spot a failing centre-bearing on an AWD Outlander?
Most owners notice a low rumble that follows road speed, or a shudder on take-off and light throttle. Underneath, the rubber support may look cracked or torn, and there can be noticeable play at the support. Always rule out tyre issues and worn CV/universal joints before calling it.

Can just the centre-bearing be replaced, or is a full prop shaft needed?
It depends on parts supply. OEMs often prefer a complete prop shaft, while quality aftermarket options may offer a serviceable centre-bearing assembly. If the shaft is split, balancing and correct phasing are critical to avoid new vibrations.
