Parts for your 2010 Subaru Exiga-Centre bearing

2010 Subaru Exiga centre-bearing: what it does and how to look after it

Based on Subaru’s own technical literature, a centre-bearing is indeed used on the 2010 Subaru Exiga. The Exiga (YA‑series) runs a two-piece propeller shaft in its Symmetrical AWD layout, and the factory setup includes a centre support bearing (often called a carrier bearing). This is detailed in the Subaru Exiga YA Factory Service Manual under Driveline/Axle – Propeller Shaft, and shown in the Subaru FAST parts catalogue, Group 27 (Propeller Shaft), which illustrates the centre support bracket and bearing as part of the assembly.

The centre-bearing’s job is simple but critical: it supports the middle of the two-piece prop shaft, keeping the shaft aligned, reducing vibration, and handling the torque delivery to the rear diff. By holding the shaft in the right spot and isolating movement through a rubber mount, it keeps noise and harshness down inside the cabin and prevents the universal or CV joints from running at nasty angles that chew out components.

There’s no fixed replacement interval for a centre-bearing, it’s a sealed unit. The smart move is a visual and hands-on check during regular servicing. Look for a torn or perished rubber isolator, signs of metal-on-metal contact, or sag around the support bracket. With the car safely raised, feel for excess play by moving the shaft near the bearing, and pay attention to road-test clues:

• Rumble, droning or humming that follows road speed, not engine rpm
• Shudder on take-off or a thump when shifting from reverse to drive
• Vibration between 60–100 km/h that doesn’t change with gears

When it’s time to replace, note that Subaru often supplies the propeller shaft as a complete assembly rather than the centre-bearing on its own, reputable aftermarket options do exist for the bearing/carrier if you’re not replacing the full shaft. Replacement involves removing heat shields, marking the flanges for phasing, unbolting the rear flange and the centre bracket, and refitting with correct alignment. Tighten fasteners to the Factory Service Manual specs, and avoid preloading the rubber by setting the car at normal ride height before final torque on the bracket. If a vibration remains after replacement, check engine and transmission mounts, rear diff bushes, and tyre balance, as these can mimic centre-bearing faults. Professional balancing of the prop shaft is recommended whenever it’s been apart.

Popular questions about the 2010 Subaru Exiga centre-bearing

Does the 2010 Subaru Exiga actually have a centre-bearing?
Yes. Subaru’s Exiga YA-series Factory Service Manual and the Subaru FAST parts catalogue (Propeller Shaft section) both show a two-piece prop shaft with a centre support (carrier) bearing fitted from factory.

Can the centre-bearing be replaced on its own, or is it a full shaft job?
From Subaru, the usual path is a complete propeller shaft assembly. However, quality aftermarket centre-bearing kits are available and commonly used. If replacing just the bearing, keep the shaft in phase and consider a balance check to avoid vibrations.

What are the common symptoms of a worn centre-bearing on an Exiga?
Typical tells include a road-speed-dependent rumble, shudder on take-off, a thump when selecting gears, and a mid-range vibration under cruise. Visual signs are a cracked or collapsed rubber isolator and excess play when you move the shaft near the bearing.
