2023 Mitsubishi Eclipse Cross Centre-Bearing

Based on Mitsubishi technical documentation, a centre-bearing is used on 2023 Eclipse Cross models equipped with S-AWC (AWD) and is not present on 2WD variants. The Mitsubishi Motors Service Manual for Eclipse Cross (GK series, Group 27A: Propeller Shaft) depicts a two-piece propeller shaft with a centre support bearing for AWD model code GK9W, while the 2WD GK1W shows no prop shaft or centre-bearing. The Mitsubishi ASA electronic parts catalogue likewise lists a “propeller shaft centre support bearing” for GK9W/S-AWC, and none for GK1W/FWD. So, for AWD owners, the centre-bearing is relevant, for 2WD, it isn’t fitted because there’s no prop shaft to support.

On S-AWC Eclipse Cross models, the centre-bearing lives mid-way along the two-piece prop shaft, keeping everything lined up as torque is sent to the rear diff. Its rubber-mounted support isolates vibration and helps the shaft run smooth at highway speeds and under load. If it’s worn, drivers may notice a droney vibration under throttle, a shudder on take-off, or a thump when backing off. Left too long, that extra movement can stress the shaft’s joints and the rear coupling, which is no fun for anyone’s wallet.

Servicing-wise, the centre-bearing isn’t a routine replacement item, but it should be inspected during scheduled services—especially if the vehicle tows, sees rough roads, or spends life fully loaded. A quick check for cracked rubber, excessive play, or misalignment goes a long way. Many workshops also road-test for driveline vibration at 60–100 km/h.

When replacement’s due, a competent workshop will:

• Mark prop shaft phasing and flange positions before removal to maintain balance.
• Inspect front and rear CV/uni joints, hanger bracket, and mount bushes at the same time.
• Refit with correct torque and support preload, then verify alignment and balance.

On some Eclipse Cross builds, the centre support bearing is available as a separate service part, on others, shops may recommend a complete prop shaft assembly if joint wear or imbalance is present. Either way, sticking to genuine-spec components and procedures from the Mitsubishi Service Manual keeps the S-AWC system happy and the cabin nice and quiet. If there’s a new vibration after tyre work or suspension repairs, it’s worth rechecking driveline angles and mounts—small changes can show up as big NVH in a modern AWD.

FAQs

Does every 2023 Eclipse Cross have a centre-bearing?
No. Only S-AWC (AWD) variants use a two-piece prop shaft with a centre-bearing. Front-wheel-drive models don’t have a prop shaft at all, so there’s no centre-bearing fitted.

What are the signs a centre-bearing is worn on an Eclipse Cross?
Common giveaways include a low-frequency vibration under acceleration, a shudder on take-off, or a dull clunk when lifting off the throttle. Visual checks can reveal cracked rubber in the support or noticeable play at the bearing mount.

Should the centre-bearing be replaced on a schedule?
There’s no fixed interval. It’s inspected during routine servicing, with replacement only when wear or damage is found. If the vehicle tows, carries heavy loads, or drives on corrugated roads, more frequent checks are smart.
