Parts for your 2007 Mitsubishi Outlander-Centre bearing

2007 Mitsubishi Outlander centre-bearing — does it have one, and what to do about it

Technical documentation shows the answer depends on drivetrain. The Mitsubishi Motors Outlander (CW-series, MY2007) with All Wheel Control (AWD) uses a two-piece propeller/tail shaft supported by a centre (center) support bearing mounted to the body. This configuration is detailed in the Mitsubishi Outlander Service/Workshop Manual for the CW platform (Propeller Shaft section) and illustrated in the Mitsubishi ASA/CAPS electronic parts catalogue for CW5W/CW6W models, which lists the propeller shaft assembly with a centre support bearing. Front-wheel drive (2WD) variants do not have a propeller shaft, so there’s no centre-bearing fitted. The Owner’s Manual AWC overview also confirms the AWD driveline layout that requires a propeller shaft to the rear differential.

For AWD-equipped 2007 Outlanders, the centre-bearing’s job is to hold the middle of the two-piece tailshaft steady, keeping it aligned and damping vibration. It sits in a rubber isolator and bolts up to a hanger bracket on the underbody, letting the shaft spin smoothly while coping with body flex and torque changes. When it’s healthy, it keeps the cabin quiet and the driveline butter-smooth, when it’s tired, you’ll often notice a low drone or hum that rises with road speed, a shudder on take-off, or a thump when loading and unloading the driveline.

As part of servicing, it’s smart to give the centre-bearing a quick once-over on AWD models. A technician will check the rubber cushion for cracking or separation, spin the shaft to feel for roughness, and look for excess movement at the hanger. Any play, torn rubber, or noisy rotation is a cue to plan a replacement. Replacement involves removing the prop shaft assembly, marking flanges for phasing, dropping heat shields as needed, and pressing the old bearing off the shaft. Many OEM catalogues list the shaft as a complete assembly, but quality aftermarket centre-bearing kits are commonly used in Australia and New Zealand. If the bearing is replaced on its own, correct pressing depth and reassembly alignment are crucial to avoid vibration, some workshops will recommend balancing the shaft if components have been disturbed.

Worth noting for 2WD owners: there’s no centre-bearing at all on front-drive 2007 Outlanders. Because drive only goes to the front wheels, there’s no rear prop shaft to support, so there’s nothing to service or replace in that spot.

• Common symptoms on AWD: droning/hum with speed, shudder on launch, clunk on load changes, visible hanger rubber deterioration.
• Good practice: inspect at regular services, address leaks from nearby seals that might contaminate the rubber, and replace worn mounts promptly to protect CV joints and couplings.

FAQs

Does every 2007 Outlander have a centre-bearing?
No. Only AWD (AWC) models have a two-piece prop shaft with a centre-bearing. Front-wheel drive versions don’t have a prop shaft running to the rear, so there’s no centre-bearing fitted. A quick look under the vehicle will tell the story: if there’s a long shaft to the rear diff with a hanger bracket near the middle, it’s AWD and has a centre-bearing.

What are the signs my centre-bearing is worn?
Typical signs are a low-frequency hum that gets louder with speed, a shudder or vibration on take-off, and a thunk when selecting drive or backing off the throttle. You might also see the rubber around the hanger splitting or sagging. These symptoms can overlap with tyre and CV joint issues, so a proper inspection is the way to go.

Can I replace just the centre-bearing, or do I need a whole shaft?
Mitsubishi often supplies the prop shaft as a complete assembly, but many workshops in AU/NZ successfully replace just the centre-bearing using quality aftermarket kits. The key is correct pressing, phasing marks, and careful reassembly. If there’s any doubt about balance or if joints are worn, a complete or rebuilt shaft may be the better long-term fix.
