Parts for your 2021 Mitsubishi Eclipse cross-Centre bearing

2021 Mitsubishi Eclipse Cross centre-bearing: what it is and when it matters

Based on technical references — including the Mitsubishi Motors Eclipse Cross (GK series, 2018–2022) Service Manual “Propeller Shaft” section and Mitsubishi’s ASA/FAST electronic parts catalogue (Group 27A: Propeller Shaft) — the 2021 Eclipse Cross equipped with AWD/S-AWC uses a two-piece propeller shaft with a centre support bearing (often called the centre-bearing). Front-wheel-drive variants don’t have a propeller shaft at all, so a centre-bearing isn’t fitted or relevant on FWD models.

For AWD owners, the centre-bearing carries and stabilises the two-piece prop shaft between the transfer unit and the rear differential. Its rubber-mounted hanger controls driveline angle and soaks up vibration, while the bearing itself supports the shaft at speed. When it’s in good nick, the car feels smooth on take-off and steady at highway pace. When it’s tired, you’ll often feel driveline shudder, hear a hum that follows road speed, or notice a clunk shifting from reverse to drive.

As part of routine servicing on an AWD Eclipse Cross, a quick underbody check of the centre-bearing is smart, especially if the vehicle sees corrugated roads, towing, or coastal conditions. Look for:

• Cracked or separated rubber in the hanger
• Excess play or roughness when the shaft is moved by hand (engine off, wheels chocked)
• Visible misalignment or shiny witness marks around the support bracket
• Oil contamination from nearby leaks that can degrade the rubber

The centre-bearing isn’t normally a lubricate-and-carry-on item, once the bearing is noisy or the hanger has torn, replacement is the fix. A competent workshop will mark the prop shaft orientation to maintain balance, support the exhaust/heat shields as needed, remove the centre support bracket, and swap the bearing/hanger assembly. They’ll then re-torque the bracket bolts, verify driveline angles, and road-test for NVH. If vibrations persist, they’ll also inspect the universal joints, guibos (if fitted), engine/gearbox mounts, and rear diff bushes — all of which can mimic a dud centre-bearing.

There’s no hard-and-fast interval for replacement — many last well past 150,000 km — but periodic inspection (say every 40,000–60,000 km or when the underbody is accessible) helps catch issues early. For FWD Eclipse Cross models, none of this applies because there’s no rear prop shaft or centre-bearing fitted.

Popular questions about 2021 Mitsubishi Eclipse Cross centre-bearing

Does every 2021 Eclipse Cross have a centre-bearing?
Only AWD/S-AWC variants do. FWD models don’t run a rear prop shaft, so there’s no centre support bearing fitted. If unsure, check the build plate for AWD or look underneath for a shaft running to the rear differential.

What are the tell-tale signs a centre-bearing is failing?
Common signs include shudder on take-off, a droning or humming noise that rises with road speed, and a dull clunk when going from reverse to drive. A torn rubber hanger or visible misalignment under the car is another giveaway. Have a technician confirm the source, as similar symptoms can come from tyres, wheel bearings, or diff bushes.

Can the centre-bearing be serviced, or does it need replacing?
The bearing and its rubber support aren’t typically serviceable in-car. Once noisy or cracked, replacement of the centre-bearing/hanger assembly is recommended. A workshop will also check prop shaft balance and related driveline components during the job.
