2016 Mitsubishi ASX centre-bearing: does it have one, and what to do about it

Based on Mitsubishi technical literature, the 2016 Mitsubishi ASX can be built either as 2WD (front‑wheel drive) or AWD (4WD/AWC). The Mitsubishi Motors Workshop Manual for RVR/ASX/Outlander Sport (2010–2017, Group 22A: Propeller Shaft) and the Mitsubishi ASA electronic parts catalogue identify that AWD/4WD ASX models (commonly coded GA2W) use a two‑piece propeller shaft with a centre support bearing. By contrast, 2WD ASX models (e.g., GA1W) have no propeller shaft to the rear, so a centre-bearing isn’t fitted or required.

Why 2WD ASX models don’t use a centre-bearing: the transaxle drives the front wheels only, so there’s no long prop shaft running down the car. Without that length and weight to support, there’s no need for a centre support bearing, the layout is lighter, simpler, and cheaper to service. This packaging is confirmed by the same factory workshop manual sections and AU/NZ service data providers used in workshops.

For AWD ASX owners, the centre-bearing matters. On these variants, the centre-bearing supports the mid-point of the two‑piece propeller shaft that sends drive to the rear differential. It keeps the shaft aligned, controls vibration, and lets the driveline cope with body and suspension movement. A healthy bearing means smooth take‑offs and quiet cruising, a tired one can make the ASX feel coarse and boomy.

• Common signs it’s on the way out: a low droning or humming that rises with road speed, vibration through the floor under load, a shudder on take‑off, or a clunk when shifting from drive to reverse.
• Inspection pointers: check the rubber isolator for cracks, separation, or oil swelling, look for looseness or sag at the mount, spin and feel for roughness once the shaft is safely supported.

Maintenance is minimal because the bearing is sealed, there’s no greasing. During regular services, a quick visual check from under the vehicle (with proper safety stands) goes a long way. If replacement’s needed, it’s a job best handled with the workshop manual open. Mark the flanges to maintain prop shaft phasing, drop heat shields as required, and torque all fasteners to spec on reassembly. It’s smart to inspect the prop shaft joints, rear diff mount, and transfer case/output seals at the same time. After refit, a road test for noise and vibration is essential.

Many aftermarket and OEM centre support bearings are available for AWD ASX models, some props come as a complete assembly. Your choice will depend on condition of the joints, budget, and parts availability in Australia or New Zealand.

FAQs

How can someone tell if their 2016 ASX actually has a centre-bearing?
Check the badge/trim and look underneath: AWD/4WD models have a prop shaft running from the front to the rear diff—with a mount roughly mid‑way that’s the centre support bearing. 2WD models won’t have a rear diff or prop shaft at all. The build plate/model code (GA2W often indicates AWD) and the owner’s manual also help confirm it.

How long does a centre-bearing typically last on an ASX?
There’s no fixed interval. Many go well past 150,000 km, but harsh roads, heavy loads, or damaged mounts can shorten life. If there’s vibration or humming that tracks road speed, have it inspected during a service rather than waiting for it to get louder.

Can the centre-bearing be replaced on its own, or is a full prop shaft needed?
On the AWD ASX, the centre support bearing can usually be replaced separately from the shaft, provided the shaft and joints are in good nick. If the joints are worn or the shaft is damaged, a complete prop assembly may be the better call for longevity and balance.
