Parts for your 2007 Subaru Legacy-Centre bearing

2007 Subaru Legacy centre-bearing: what it is, and why it matters

Based on technical literature, the 2007 Subaru Legacy (BL/BP series) with Symmetrical AWD uses a two‑piece propeller shaft with a rubber‑isolated centre support bearing. This is shown in the Subaru Factory Service Manual under Driveline/Axle – Propeller Shaft, and reflected in Subaru’s parts catalogue where the propeller shaft assembly includes the centre bearing and bracket. Independent repair guides (e.g., Haynes 2000–2009 Legacy/Outback) also describe the centre support bearing on AWD models. In Australia and New Zealand, 2007 Legacy/Liberty models are AWD as standard, so a centre‑bearing is fitted.

The centre‑bearing on a 2007 Subaru Legacy supports the middle of the two‑piece prop shaft, keeping it running true between the gearbox and rear diff. It damps vibration with a rubber mount and helps the driveline cope with engine movement, road shock, and changes in angle over bumps. When healthy, it keeps the cabin calm and the AWD system smooth and quiet on Kiwi and Aussie roads.

As part of routine servicing, it pays to eyeball the centre‑bearing for split rubber, sagging, or metal‑to‑metal contact, and to spin the shaft by hand to feel for roughness. There’s no periodic lubrication—these bearings are sealed—but heat shields should be intact and leaks from the gearbox or diff sorted so oil doesn’t attack the rubber. Common tell‑tales of a crook bearing are a low‑speed shudder on take‑off, a droning or rumble that peaks around 60–90 km/h under load, and a thump when lifting off.

When replacement is needed, most driveline shops recommend dropping the exhaust and undertrays, marking the flanges so phasing stays spot‑on, then removing the shaft, pressing off the old bearing, and fitting a quality replacement with the bracket oriented correctly. Subaru typically supplies the complete prop shaft as an assembly, but the centre‑bearing can be replaced separately by a driveline specialist. It’s smart to check the universal joints, rear diff bushings, and engine/gearbox mounts at the same time. On refit, align the bracket without twisting the rubber, torque the fasteners properly, and road‑test for any residual vibration. If the rubber has torn or the bearing has play or roughness, replacement sooner rather than later saves tyres, diff mounts, and everyone’s sanity on the motorway.

Popular questions about the 2007 Subaru Legacy centre‑bearing

Does every 2007 Legacy have a centre‑bearing?
All Australian and New Zealand 2007 Legacy/Liberty models are AWD and use a two‑piece prop shaft with a centre‑bearing. In markets where a FWD variant exists, that version doesn’t have a rear prop shaft, so no centre‑bearing.

How long does the centre‑bearing last, and what are the signs it’s failing?
Many last well past 150,000 km, but heat, age, and road conditions matter. Symptoms include a take‑off shudder, a mid‑speed drone that’s worse on throttle, and visible cracks or sagging in the rubber support.

Can just the centre‑bearing be replaced, or is a full prop shaft needed?
Subaru supplies the full prop shaft, but driveline specialists can press off and replace the centre‑bearing and rebalance the shaft. If U‑joints are worn or the shaft is damaged, a complete assembly may be the better bet.
