Parts for your 2015 Mitsubishi Asx-Centre bearing

2015 Mitsubishi ASX centre-bearing — does this model use one?

Short answer: it depends on the drivetrain. Technical references from Mitsubishi’s factory workshop manuals (Group 22A: Propeller Shaft for Outlander Sport/ASX 4WD) and the Mitsubishi ASA electronic parts catalogue show that only the all-wheel-drive ASX variants use a two-piece propeller shaft with a centre-bearing (also called a carrier bearing). Front-wheel-drive ASX models don’t have a rear prop shaft at all, so there’s no centre-bearing fitted.

Why there’s no centre-bearing on FWD ASX: the 2WD layout uses a transverse engine and drives the front wheels directly via short half-shafts, eliminating the long propeller shaft that would otherwise need a mid-support. Mitsubishi’s service literature for the ASX/RVR platform confirms the centre-bearing appears only in the 4WD propeller shaft assembly, not in 2WD configurations.

If your 2015 ASX is AWD, here’s the lowdown on its centre-bearing. The centre-bearing sits mid-way along the two-piece prop shaft, supporting it so the shaft runs true from the transfer case to the rear differential. Its job is to control vibration, keep alignment tight under load, and reduce wear on the universal joints. When the rubber isolator or bearing wears, you’ll typically notice a droning or humming between about 60–90 km/h, a shudder on take-off, or a thump when getting on and off the throttle.

Servicing advice is simple: it’s not a routine replace-at-X-kilometres item, but it should be inspected at scheduled services or if any of the above symptoms appear. A visual check for cracked rubber, sagging support, or shiny contact points is a good start. During replacement, a few best-practice tips matter:

• Mark the prop shaft orientation before removal to preserve balance.
• Support the shaft when unbolting the bearing to avoid stressing the joints.
• Centre the new bearing in its slots before final torque, then road-test and recheck for vibration.

It’s smart to assess the universal joints, flex couplings (if fitted), and rear diff bushes at the same time, a worn bush can mimic a dud centre-bearing. Quality matters here—choose an OE-equivalent bearing and mount, as cheaper rubber can collapse early, especially with towing or rough Kiwi and Aussie roads. Many owners see well over 120,000 km from a healthy centre-bearing, but high heat, dust, and constant stop-start can shorten its life. If vibrations persist after replacement, have the shaft balance checked by a driveline specialist.

Common signs it’s time: increasing vibration under load, rhythmic humming that changes with road speed (not engine rpm), and a clunk on take-off. Ignoring it risks taking out the U-joints or transfer case seal, so don’t leave it too long once the noise shows up.

FAQs

Does every 2015 Mitsubishi ASX have a centre-bearing?
Not every one. Only the AWD variants use a two-piece propeller shaft with a centre-bearing. If the vehicle is front-wheel drive, there’s no rear prop shaft and therefore no centre-bearing to service or replace.

What are the signs of a worn centre-bearing on an AWD ASX?
Expect a droning or humming that follows road speed, a shudder on take-off, or a thump when getting on and off the throttle. A visual check may show cracked rubber or a sagging carrier. If in doubt, have a technician road-test and inspect the prop shaft assembly.

Can it be driven with a noisy centre-bearing?
It’ll usually still move, but it’s not a great idea. Continued driving can worsen vibration and may damage the universal joints or seals. Plan a prompt inspection and repair to keep everything smooth and safe.
