Parts for your 2015 Subaru Exiga-Centre bearing

2015 Subaru Exiga centre‑bearing: what it is, why it matters, and how to look after it

Based on technical references, the 2015 Subaru Exiga does use a centre‑bearing (also called a carrier bearing) on its two‑piece propeller/tailshaft. This is documented in the Subaru Exiga (YA5/YA9) Service Manual under the Propeller Shaft section, and reflected in the Subaru FAST electronic parts catalogue for 2015 Exiga models, which lists a centre support bearing as part of the propeller shaft assembly.

On the 2015 Subaru Exiga, the centre‑bearing sits mid‑way along the two‑piece tailshaft and supports the shaft as it runs from the transmission to the rear diff. Its job is to keep everything aligned under load, isolate vibration through a rubber mount, and help the AWD system deliver power smoothly. When it’s healthy, the Exiga feels tight and quiet, when it’s tired, it’ll let the cabin know about it with rumble, drone, or a shudder on take‑off.

There’s no fixed replacement interval for a centre‑bearing, but it should get a quick once‑over at every service. A mechanic will check the rubber isolator for cracks or separation, feel for roughness or free play at the bearing, and make sure the support bracket is secure. Heat, age, hard launches, and worn engine/gearbox mounts can all speed up wear.

Tell‑tale symptoms owners might notice include:

• Droning or humming that rises with road speed, not engine revs
• Vibration or shudder on acceleration, especially uphill
• Clunk as drive is first taken up

From the factory, Subaru treats the Exiga’s propeller shaft as a sealed assembly, the centre‑bearing isn’t listed as a separate OE service part in many markets. That means the official fix for a noisy or loose bearing is to replace the complete tailshaft. In practice, a driveline specialist can often press off the old bearing and fit an aftermarket replacement, then re‑balance the shaft—handy if the rest of the assembly is in good nick and budgets matter.

If replacement’s on the cards, it pays to mark the shaft orientation before removal to preserve balance, torque the support bracket and flange bolts correctly, and check the condition of surrounding mounts while it’s apart. After refit, a road test under varying loads will confirm any vibration is gone. Keeping underbody heat shields in place and avoiding torn mounts goes a long way to extending the life of the centre‑bearing and keeping the Exiga’s driveline butter‑smooth.

FAQs

Does the 2015 Subaru Exiga have a centre‑bearing?
Yes. The Exiga uses a two‑piece tailshaft with a centre support bearing. This is shown in the Subaru service manual’s propeller shaft procedures and the Subaru FAST parts catalogue for the 2015 model year.

What are the signs a centre‑bearing is failing on a 2015 Exiga?
Common clues are a droning or humming that tracks with speed, a shudder under acceleration, or a clunk when taking off. If the rubber around the carrier looks torn or the bearing feels rough or loose, it’s due for attention.

Can the centre‑bearing be replaced on its own?
Subaru supplies the propeller shaft as a complete unit in many markets, so the official path is full assembly replacement. However, a driveline specialist can usually press in an aftermarket centre‑bearing and re‑balance the shaft, which can be a cost‑effective repair if the rest of the assembly is sound.
