Parts for your 2011 Mitsubishi Outlander-Centre bearing

2011 Mitsubishi Outlander centre-bearing

Technical documentation confirms a centre-bearing (also called a centre support or carrier bearing) is used on 2011 Mitsubishi Outlander all-wheel-drive (AWD/4WD) variants, but not on front-wheel-drive (2WD) models. The Mitsubishi workshop manual (Propeller Shaft section) and the Mitsubishi ASA/EPC parts catalogue for the CW-series Outlander show a two-piece rear propeller shaft with a centre support bearing and bracket on AWD models, 2WD versions have no rear prop shaft, so no centre-bearing applies.

On AWD Outlanders, the centre-bearing supports the two-piece propeller shaft running from the transaxle to the rear differential. Its job is to hold the shaft steady mid-span, keeping everything aligned and reducing vibration as torque is sent to the rear wheels. The rubber-mounted support isolates driveline buzz, while the bearing itself lets the shaft spin smoothly at road speeds.

When the centre-bearing ages, the rubber can perish or the bearing can wear, which shows up as vibration on take-off, a droning or humming that rises with road speed, or a clunk when going on and off the throttle. Left unchecked, that extra movement can stress the prop shaft CV/universal joints and mounts, so timely attention is smart.

There’s no scheduled replacement interval, it’s a “inspect and replace if needed” item during regular servicing. A thorough check involves looking for cracked or sagging rubber, roughness when the shaft is rotated by hand (with the vehicle safely raised), and any visible play at the bearing. Because the bearing lives under the car, road grime and water can accelerate wear, especially if the vehicle sees gravel or coastal use.

When replacement is required, best practice is to remove the complete propeller shaft, mark its phasing, and either press out and replace the bearing on the bench or fit a quality replacement support assembly. Rebalancing the shaft after work is recommended if the assembly has been disturbed. New hardware and correct bracket alignment help prevent future vibration. While there, it’s wise to inspect the rear diff coupling, prop shaft CV/uni joints, and mounts, and check for leaks at adjoining seals. Road-test for any residual shudder or noise once refitted.

A well-fitted centre-bearing restores that smooth, quiet feel the Outlander is known for, and helps protect the rest of the AWD driveline for many more kilometres.

• Typical warning signs: shudder under load, droning at 60–100 km/h, clunks on throttle changes, visible sag in the support rubber.
• Related checks: prop shaft joints, rear diff mount, coupling, bracket alignment and fasteners.

FAQs

Does every 2011 Outlander have a centre-bearing?
An AWD/4WD 2011 Outlander does, a 2WD version does not. The centre-bearing only exists where there’s a two-piece rear propeller shaft. Unsure which you have? Look for a prop shaft running down the centre tunnel to a rear differential, or confirm via the build plate/VIN details and drivetrain badge.

What are the common symptoms of a failing centre-bearing?
Owners often notice a low-frequency vibration on take-off, a humming that rises with speed, or a clunk as load changes. Visual inspection may reveal cracked or sagging rubber around the carrier. These symptoms can overlap with worn prop shaft joints or mounts, so a proper underbody check is worthwhile.

Is it safe to keep driving with a noisy centre-bearing?
Short trips may be possible, but it’s not ideal. Excess movement can accelerate wear in the shaft joints and stress the coupling and mounts. Prompt inspection and repair usually saves money by preventing knock-on damage and restores a smoother, quieter ride.
