Parts for your 2025 Mitsubishi Eclipse cross-Centre bearing

2025 Mitsubishi Eclipse Cross centre-bearing: what it is, and when it matters

Based on Mitsubishi Motors service documentation for the Eclipse Cross GK/GN series (Propeller Shaft section) and OEM parts catalogues for S-AWC models, the all-wheel drive Eclipse Cross uses a two‑piece propeller shaft supported by a centre support bearing. The 2025 model continues this driveline layout. Front‑wheel drive variants have no rear prop shaft, so a centre-bearing isn’t fitted or relevant on FWD trims.

For AWD owners, the centre-bearing lives mid‑way along the prop shaft, cradled in a rubber mount. Its job is to support the two‑piece shaft, keep alignment on point, and soak up vibration as torque runs from the transaxle to the rear diff. Without a healthy centre-bearing, the shaft can go out of line, causing shudder on take‑off, a droning or hum around 60–100 km/h, or a thump when shifting between load and coast.

There’s no scheduled replacement interval in Mitsubishi literature, it’s an inspect-and-replace item. A good workshop will check the centre-bearing at each service on AWD Eclipse Cross models—looking for torn rubber, cracked mount, excess play in the bearing, or witness marks from contact. If the support rubber is perished or the bearing feels rough or loose, plan a replacement to protect the prop shaft joints and rear diff.

Replacement can be done as a bearing/support assembly or, depending on wear and balance, as a complete prop shaft. Because shaft phasing and balance are critical, technicians mark the shaft before removal, use new hardware where specified, and torque to spec. After refit, a road test checks for vibration under load and on overrun. It’s also a smart time to inspect the prop shaft joints (CV or universal, depending on build), centreline, and transfer/diff seals.

To help the centre-bearing live a long life: avoid hard impacts off‑road that could stress the mount, don’t jack or support the vehicle under the prop shaft, and keep solvents and heat away from the bearing support rubber. In typical Aussie and Kiwi conditions, many centre-bearings go well past 120,000–200,000 kilometres, but high towing loads, rough roads, or under‑body contamination can bring that forward. If the Eclipse Cross is FWD, relax—there’s no centre-bearing fitted, so there’s nothing to service here.

• Common symptoms: shudder on launch, mid‑speed droning, clunk on load change, visible play at the support.
• Service tip: inspect at every routine service on AWD, replace at first signs of play or rubber degradation.

FAQs

Does a 2WD 2025 Eclipse Cross have a centre-bearing?
No. Front‑wheel drive Eclipse Cross models don’t have a rear propeller shaft, so there’s no centre-bearing. Only S‑AWC (AWD) variants use a two‑piece prop shaft with a centre support bearing.

How long does the centre-bearing last on an AWD Eclipse Cross?
There’s no fixed interval, but many last 120,000–200,000 km or more. Life depends on use—regular towing, rough roads, or under‑body contamination can accelerate wear. Inspect the mount and bearing at each service and act early if there’s play, noise, or torn rubber.

Can the centre-bearing be replaced without changing the whole prop shaft?
Often, yes—the support bearing/mount can be serviced on its own. However, because shaft balance and phasing are critical, some workshops prefer replacing or rebalancing the entire assembly if there’s additional wear or runout. A proper inspection will determine the best path.
