Parts for your 2010 Subaru Exiga-Driveshafts

2010 Subaru Exiga driveshafts: what they do and when to service them

Driveshafts are absolutely relevant to the 2010 Subaru Exiga. Technical documentation makes this clear: the Subaru Exiga (YA series) Factory Service Manual includes “Drive Shaft System” procedures for the front axles and a separate “Propeller Shaft” section for Symmetrical AWD models. Likewise, the Subaru FAST electronic parts catalogue lists front drive shaft assemblies (LH/RH) for all variants and a propeller shaft assembly for AWD trims. That means every 2010 Exiga has front CV axle driveshafts, and AWD versions add a centre propeller shaft to drive the rear differential.

On the Exiga, the front driveshafts transfer torque from the transaxle to the front hubs, with constant-velocity (CV) joints allowing full steering angle and suspension travel without vibration. AWD models also use a propeller shaft down the centre of the car to send drive to the rear diff, helping deliver the planted feel Subaru’s Symmetrical AWD is known for. When these shafts and joints are healthy, the Exiga pulls smoothly and quietly, with no shudder under load and no clicks on full lock.

As part of regular servicing, it’s smart to inspect the CV boots every 10,000–15,000 km or at each service. Look for splits, grease fling inside the wheel, or perished rubber. A torn boot lets out grease and lets in grit, which quickly chews out a CV joint. Catching a boot early usually means a clean, re-grease and boot replacement rather than a whole driveshaft. Listen for tell-tale clicking while turning at low speed (outer CV wear) and feel for vibration under acceleration (inner CV or prop shaft issue on AWD). Also check for excessive play at the joints and any clunks on take-off.

On AWD Exiga models, have the propeller shaft’s universal joints and centre support bearing checked for play and the shaft inspected for dents. While most Subaru prop shafts are non-serviceable at the UJs, timely replacement prevents collateral damage to the gearbox or diff. After any driveshaft work, a wheel alignment and torque check on axle nuts is good practice. Quality replacement shafts or genuine boots, fitted with the correct spec grease and new clamps, will keep the Exiga driving sweet for many more kilometres on Aussie and Kiwi roads.
