2017 Subaru XV centre-bearing: what it does and how to look after it

Based on Subaru’s workshop manual for the Impreza/XV GP platform (Driveline/Propeller Shaft section) and the Subaru electronic parts catalogue (FAST) which lists a propeller shaft centre support for 2012–2017 XV, the 2017 Subaru XV runs a two-piece tailshaft with a centre-bearing (centre support). Many OE catalogues also note the bearing is supplied as part of the complete propeller shaft assembly.

The XV’s centre-bearing sits midway along the two-piece tailshaft, cradled in a rubber mount and bolted to the body. Its job is to support the shaft, keep the driveline aligned under load, and soak up vibration as the suspension and engine move about. That support means smoother take-offs, less droning at highway speeds, and longer life for universal joints and diff/gearbox seals.

There’s no fixed replacement interval, but it deserves a look at every service—especially if the car does country kilometres on corrugations or carries gear on rough tracks. The tell-tales are pretty familiar: a whirring or droning that rises with road speed, a shudder on take-off, thumps as you load and unload the throttle, or visible cracking/tearing of the rubber support. Excessive play when the shaft is levered by hand with the vehicle safely supported is another red flag.

On many Subarus of this era the centre-bearing isn’t sold separately from the propeller shaft, so the usual repair is to replace the complete assembly. A quality driveline shop can sometimes press in a compatible bearing and re-bush the support, but correct phasing and dynamic balancing are critical to avoid new vibrations. If the XV is lifted or lowered, driveline angles change and can accelerate wear, checking mounts, crossmember bushes, and uni joints at the same time is smart.

Replacement tips for technicians and savvy DIYers:

• Mark flanges and yokes before removal to preserve phasing and balance.
• Support the shaft to avoid stressing the slip joint and seals.
• Loosely mount the centre-bearing bracket, settle the car at normal ride height, then tighten to avoid preloading the rubber.
• Road-test for vibration across 40–110 km/h, recheck fasteners, and inspect for any fresh weeps at the trans or diff.

Get the centre-bearing right and the XV stays quiet, tight, and happy on both the motorway and the metal roads.

FAQs

Does a 2017 Subaru XV have a centre-bearing?
Yes. The first‑gen XV (2012–2017 GP platform) uses a two-piece tailshaft with a body-mounted centre-bearing. This is documented in Subaru’s workshop manual under the Propeller Shaft section and reflected in the OE parts catalogue.

Can the XV’s centre-bearing be replaced on its own?
From Subaru, the bearing typically comes integrated with the complete prop shaft. Some driveline specialists can fit a replacement bearing and re-bush the support, but the shaft must be rebalanced and correctly phased. If balance or phasing is off, new vibrations can appear.

What does a failing centre-bearing sound or feel like?
Common signs are a droning or rumbling that tracks with speed, a shudder on take-off, and thumps when getting on and off the throttle. Torn rubber around the support or obvious play when the shaft is levered are also giveaways.
