Parts for your 2008 Subaru Exiga-Centre bearing

2008 Subaru Exiga centre-bearing: what it does and how to look after it

On the 2008 Subaru Exiga (YA series), a centre-bearing is fitted on all all-wheel drive (AWD) models because they use a two‑piece propeller shaft. This layout, including the centre support bearing and bracket, is documented in the Subaru Exiga Service Manual (YA, Driveline/Axle – Propeller Shaft) and shown in the Subaru FAST electronic parts catalogue for YA5/YA9, which lists a support bearing assembly (commonly referenced as 41022AG000) within the propeller shaft group. Front‑wheel drive variants don’t have a propeller shaft, so a centre-bearing isn’t used on those.

The centre-bearing’s job on an AWD Exiga is simple but vital: it supports the middle of the two‑piece tailshaft, keeps the shaft aligned under load, and helps control vibration and noise. With the engine and transmission up front and the rear diff out back, that extra support in the middle lets the driveline run true at highway speeds and during hard acceleration without shudder.

It’s a sealed bearing with a rubber isolator, so there’s no greasing or scheduled replacement in normal servicing. That said, it should be visually checked whenever the Exiga is on a hoist—think routine inspections around 20,000–30,000 km or during any underbody work. A quick look for torn rubber, excessive movement, or contact between the shaft and the bearing housing goes a long way. If road-testing raises a question, a mechanic can also feel for roughness by rotating the tailshaft by hand with the car safely supported.

• Common signs of a tired centre-bearing on an Exiga include a low-speed take‑off shudder, a droning or rumbling that changes with road speed (not engine revs), and a clunk when shifting from drive to reverse as the shaft loads up.
• If left too long, vibration can accelerate wear in the tailshaft joints and rear diff mount bushes.

When replacement’s needed, many workshops prefer swapping the complete propeller shaft assembly to maintain balance and phasing exactly as Subaru intended. Quality aftermarket options also exist for the bearing and carrier, but care is required to press parts correctly and to keep the shaft’s original alignment marks. Bracket bolts should be torqued to the service manual spec, the bearing shouldn’t be preloaded by pulling the bracket off‑centre, and any shims must go back exactly where they came from. A short test drive afterwards—checking for smooth take‑off and no new harmonics at 60–100 km/h—confirms the job’s right.

Note for buyers and import owners: if the 2008 Exiga in question is a FWD variant, there’s no centre-bearing fitted, because there’s no tailshaft running to the rear diff.

Popular questions about 2008 Subaru Exiga centre-bearing

Does every 2008 Exiga have a centre-bearing?
AWD models do, because they run a two‑piece propeller shaft with a centre support bearing. Some markets saw FWD Exiga variants, those don’t have a tailshaft and therefore don’t use a centre-bearing. Checking the VIN build spec or looking underneath for a rear diff is a quick way to tell.

How long should a centre-bearing last on an Exiga?
There’s no fixed interval, but many see well over 150,000 km. Life depends on driving conditions, heat, and whether the rubber support has aged. Regular underbody inspections during services help catch issues early before vibration causes collateral wear.

Can just the centre-bearing be replaced, or does the whole tailshaft need doing?
Subaru supplies the complete shaft assembly as the default fix, which preserves balance and phasing. However, competent driveline shops can replace the bearing and carrier on their own. If going the component route, insist on correct press procedures, alignment marks, and a balance check if required.
