Parts for your 2018 Mitsubishi Asx-Centre bearing

2018 Mitsubishi ASX centre-bearing: what owners need to know

For Australian and New Zealand delivered 2018 Mitsubishi ASX models, a centre-bearing (also known as a carrier bearing) is not fitted or required. The ASX in these markets is a front-wheel-drive SUV with a transverse engine and transaxle. That layout drives the front wheels directly via short CV shafts, so there’s no long, two-piece tailshaft running down the car—and no need for a centre support bearing.

Why it’s not used on the 2018 ASX:

• Drivetrain design: Transverse FWD transaxle with front CV shafts only, no propeller shaft to the rear.
• No AWD spec in AU/NZ for 2018: Without a rear differential, there’s nothing to connect via a tailshaft.
• Packaging and weight: The compact FWD setup keeps weight and complexity down, which improves fuel economy and reduces maintenance points.

Technical references that support this include: Mitsubishi Motors Australia 2018 ASX brochure/specification sheets (listing 2WD only for local trims), the 2018 ASX workshop/service information for AU/NZ models (no propeller shaft or centre support bearing sections or parts), and the Mitsubishi ASA electronic parts catalogue for AU/NZ VIN ranges (no centre-bearing or tailshaft assemblies listed for 2018 ASX). Collectively, these sources confirm the centre-bearing isn’t part of the vehicle’s driveline in these markets.

If an owner is experiencing driveline-type noises or vibration on a 2018 ASX, it’s more likely to be tyres (cupping or out-of-round), front wheel bearings, CV joints/boots, engine or transmission mounts, or even a bent wheel. A proper road test and inspection will usually pinpoint it quickly.

FAQs

Does a 2018 Mitsubishi ASX have a centre-bearing?
No. AU/NZ 2018 ASX models are front-wheel drive with no tailshaft, so there’s no centre-bearing. Some earlier overseas ASX/RVR variants offered AWD, but local 2018 trims didn’t. If the vehicle is a private import with AWD hardware, a prop shaft (and potentially a carrier bearing) could be present—check the VIN against a parts catalogue.

What’s causing a humming or vibration if there’s no centre-bearing?
Common culprits include uneven or worn tyres, a failing front wheel bearing, an outer CV joint starting to click, or tired engine/trans mounts. Tyre pressures and wheel balance are quick wins to check first. If the vibration changes with road speed rather than engine revs, focus on tyres, wheels and hubs.

Can a centre-bearing be fitted to an ASX?
Not on a standard AU/NZ 2018 ASX. There’s no rear diff or tailshaft to support. Converting to AWD is a major engineering exercise involving a transfer unit, prop shaft, diff, subframes and control modules—well beyond normal servicing or sensible modification for this platform.
