Parts for your 2019 Mitsubishi Asx-Centre bearing

2019 Mitsubishi ASX centre-bearing: is it used, and does it need servicing?

Short answer: a centre-bearing isn’t fitted to Australian or New Zealand 2019 Mitsubishi ASX models, so it’s not a service item on these vehicles. Those market cars are front‑wheel drive only, with a transverse engine and no propeller shaft running to a rear differential. A centre-bearing (also called a carrier/support bearing) is only used on two‑piece prop shafts, which you’ll typically find on rear‑wheel drive or certain all‑wheel drive layouts.

On the 2019 ASX sold locally, drive is handled by the front transaxle and a pair of front CV shafts. Because there’s no long prop shaft under the car, there’s nowhere for a centre-bearing to live. The bearings that matter for routine servicing on a local 2019 ASX are the front wheel bearings and the CV joints/boots, along with transmission/diff fluid service per the schedule.

There are ASX/RVR/Outlander Sport variants in other markets with on‑demand 4WD. Those versions use a propeller shaft to the rear final drive, and some are built as a two‑piece shaft with a centre support bearing mounted to the body tunnel. That’s the configuration where a centre-bearing applies—just not to the AU/NZ 2019 ASX range.

• If a 2019 ASX in Australia or New Zealand develops humming, droning, or vibration under acceleration, common culprits are tyre noise/cupping, front wheel bearings, engine/gearbox mounts, or CV joints—rather than any centre-bearing.
• Owning a used import AWD RVR/ASX from Japan or another market? That vehicle may have a two‑piece prop shaft with a centre support bearing. In that case, inspection for play, torn rubber isolator, or roughness is part of driveline servicing.

FAQs

Does a 2019 Mitsubishi ASX in Australia or New Zealand have a centre-bearing?
No. Local 2019 ASX models are front‑wheel drive with no rear prop shaft, so there’s no centre-bearing fitted or required.

I’m getting a droning noise at 80–100 km/h—could it be the centre-bearing on my 2019 ASX?
Unlikely on a local car, because there isn’t one. Check tyre condition and pressures first, then have a workshop inspect front wheel bearings, CV joints/boots, and engine/gearbox mounts. Those are the usual suspects for this platform.

I’ve got a used‑import AWD RVR/ASX—does it have a centre support bearing and what should be serviced?
Many AWD imports use a two‑piece prop shaft with a centre support bearing. During servicing, a tech should check the bearing for roughness or excess play, inspect the rubber mount for cracking, and verify prop shaft balance and U‑joint/CV coupling condition.
