Parts for your 2010 Subaru Impreza-Driveshafts

2010 Subaru Impreza driveshafts — what they do and how to look after them

Driveshafts are absolutely relevant and fitted to the 2010 Subaru Impreza. Technical references including the Subaru Factory Service Manual for GE/GH/GR models (MY2008–2011) under “Front Axle” and “Propeller Shaft”, the Subaru FAST parts catalogue, and common workshop texts such as the Haynes Repair Manual (Impreza 2008–2014) all show the vehicle uses CV-jointed front and rear drive shafts, plus a two-piece propeller shaft to the rear differential on All-Wheel Drive models. Australian and New Zealand–delivered 2010 Imprezas are AWD, so the full set is present.

On this model, the driveshafts do two key jobs. The four CV halfshafts send torque from the transaxle and rear diff to each wheel while allowing for steering angle and suspension travel. The centre propeller shaft carries drive to the rear diff and includes a centre support bearing to keep things smooth. Together, they’re the heart of Subaru’s Symmetrical AWD feel—surefooted, predictable and ready for slippery roads.

There’s no fixed replacement interval, it’s condition-based. Regular servicing should include a quick look for tell-tales: split or weeping CV boots, flung grease inside the wheel arches, clicking on tight turns, shudder on take-off, vibration at motorway speeds, clunks when shifting from drive to coast, or play in the centre support bearing. Any of these warrant further inspection.

• Inspect CV boots at each service (around every 10,000–15,000 km). Replace torn boots promptly to save the joint.
• Check the prop shaft’s centre bearing rubber and listen for droning or vibration under load.
• If a shaft is removed, mark flange positions to maintain balance and use new flange/axle nuts as specified by the FSM.
• Quality grease and proper boot clamps matter, cheap clamps can sling off and restart the problem.

Many Subaru prop shafts have staked (non-serviceable) universal joints, workshops often fit a complete new or professionally rebuilt assembly if joints are worn. CV halfshafts can be replaced individually with genuine or reputable aftermarket units. After any driveline work, a short road test to check for vibrations is smart practice, and a wheel alignment is worthwhile if suspension has been disturbed. Kept clean, greased, and balanced, the Impreza’s driveshafts will quietly get on with the job for years.

Does the 2010 Impreza actually have a driveshaft?

Yes. Technical sources including the Subaru Factory Service Manual (GE/GH/GR, MY2008–2011), Subaru FAST parts listings, and the Haynes Repair Manual confirm a two-piece propeller shaft to the rear differential plus four CV halfshafts. Australian and New Zealand models of this year are AWD, so all are fitted.

What are common signs of worn driveshafts on a 2010 Impreza?

Clicking on full lock, shudder on take-off, grease sprayed around the wheel well, vibration at 80–110 km/h, and clunks when loading/unloading the driveline are classic signs. A droopy or noisy centre support bearing can add a droning vibe through the cabin.

Can the centre bearing or U-joints be replaced separately?

The centre support bearing can often be replaced, but many OEM prop shaft U-joints are staked and not designed for DIY servicing. Professional rebuilders can fit serviceable joints and rebalance the shaft, or a complete new assembly can be installed depending on cost and condition.
