Parts for your 2013 Subaru Impreza-Centre bearing

2013 Subaru Impreza centre-bearing: what it does and when to replace it

Technical sources confirm the 2013 Subaru Impreza (GP/GJ) AWD models use a two-piece propeller shaft with a centre-bearing (also called a carrier or centre support bearing). The Subaru Service Manual for 2012–2016 Impreza lists the centre-bearing and bracket in the Propeller Shaft section, and Subaru’s parts catalogues show the centre-bearing as part of the prop shaft assembly for these AWD cars. Note: in markets where front‑wheel‑drive variants existed, there’s no prop shaft and therefore no centre-bearing. In Australia and New Zealand, the 2013 Impreza is Symmetrical AWD, so the centre-bearing is fitted.

The centre-bearing sits mid-way along the Impreza’s two-piece prop shaft, holding the shaft steady as torque heads from the gearbox to the rear diff. It keeps the driveline aligned, tames vibrations at speed, and lets the shaft move slightly with the body and engine mounts without shaking the cabin. On these Subarus, it’s a rubber‑insulated bearing mounted to a bracket under the car, designed to cope with daily use and the odd rough road without complaint.

There’s no routine lubrication needed—the bearing is sealed—but it’s smart to have it inspected during regular servicing. A quick check every 20,000 km for rubber cracking, sag, or noise is cheap insurance. Common tell-tales it’s on the way out include:

• Shudder or vibration on take‑off, or a droning vibration between about 40–80 km/h.
• A thump when shifting from reverse to drive/first, or on/off throttle.
• Visible tears in the rubber support or excessive play at the bearing.

Replacement strategy depends on parts availability and tooling. Subaru typically supplies the complete propeller shaft as a balanced assembly, which is the cleanest fix. Aftermarket centre-bearings exist, but pressing one on/off the shaft and keeping correct preload and balance is a specialist job—most workshops will send the shaft to a driveline shop for bearing replacement and rebalancing.

If replacing, mark the shaft orientation before removal, support the exhaust and heat shields, and use new fasteners where specified. Refit the centre-bearing bracket without preloading the rubber, then torque the flanges to spec. A road test to check for any new vibration, plus a quick recheck of fasteners after a few hundred kilometres, rounds it out.

To help the new bearing live a long life, keep engine, transmission, and diff mounts in good nick, avoid aggressive power launches on high‑grip surfaces, and be mindful that big suspension lifts or driveline angle changes can stress the rubber support.

Popular questions

Does every 2013 Subaru Impreza have a centre-bearing?
All Australian and New Zealand 2013 Impreza models are AWD and use a two‑piece prop shaft with a centre-bearing. In some overseas markets, front‑wheel‑drive versions exist and those do not have a centre-bearing.

What are the common symptoms of a worn centre-bearing on a 2013 Impreza?
Drivers usually notice a vibration on take‑off, a droning buzz at certain speeds, or a dull clunk when going on and off the throttle. A visual check often shows cracked or sagging rubber in the bearing support.

Can just the centre-bearing be replaced, or does the whole prop shaft need doing?
Subaru commonly supplies the prop shaft as a complete, balanced unit. The bearing can be replaced separately with quality aftermarket parts, but it’s best handled by a driveline specialist so the shaft is pressed, assembled, and rebalanced correctly.
