Parts for your 2011 Subaru Impreza-Driveshafts

2011 Subaru Impreza driveshafts

Technical sources confirm driveshafts are absolutely used on the 2011 Subaru Impreza. The Subaru Factory Service Manual for 2011MY Impreza (GE/GH/GR/GV—Chassis: Drive Shaft and Propeller Shaft), Subaru’s Electronic Parts Catalogue, and Subaru Australia’s material on Symmetrical All-Wheel Drive all detail a two-piece propeller shaft to the rear differential plus front and rear CV driveshafts.

On this model, the driveshafts do the hard yakka of getting torque from the transaxle to the wheels. Up front, two CV shafts connect the front differential to the hubs. A two-piece propeller shaft with a centre support bearing runs down the tunnel to the rear diff, and a pair of rear CV shafts finish the job to the back wheels. Subaru’s Symmetrical AWD layout keeps these components nicely in line, which helps balance, traction, and wear.

There’s no fixed replacement interval for driveshafts, but they love regular inspections. At each service (typically every 10,000–15,000 km, or as per your workshop’s schedule), a tech should check CV boots for splits, loose clamps, or flung grease, feel the prop shaft’s centre bearing for play, and look for rust or dent damage on the tubes. Any clicking on tight turns usually points to an outer CV joint on the way out. A shudder on take-off or a steady-speed vibration (often 60–100 km/h) can hint at a worn inner CV joint, out-of-balance prop shaft, tired centre bearing, or U-joint issues.

When replacing a CV shaft, quality matters—cheap shafts can introduce vibration. Fresh axle nuts and hub seals are wise, and torqueing everything to the factory spec is a must. CV joints are sealed, if a boot tears early and the joint isn’t noisy, a prompt boot-and-grease repair can save the shaft. For the prop shaft, Subaru commonly supplies it as an assembly, many U-joints are staked and not user-serviceable, so it’s either a full replacement or a specialist rebuild. After any driveline work, a road test under load is essential to confirm smoothness. Wheel alignment isn’t normally required for shaft replacement unless suspension components were disturbed. Keeping diff and transmission fluids on schedule also helps the whole driveline live a longer, quieter life.

• Watch for: clicking on turns, vibration under load or at highway speeds, grease spray around CV boots.
• Service tip: inspect boots and bearings every service, fix small issues before they snowball.

FAQ

How long do driveshafts last on a 2011 Subaru Impreza?

With intact boots and sensible driving, many CV shafts last well past 150,000–250,000 km. The propeller shaft can go even longer if the centre bearing and U-joints stay healthy. Harsh roads, lifted suspension, track work, or torn boots shorten that lifespan. Regular inspections are the best way to catch problems early.

What are the symptoms of a failing CV joint or prop shaft on an Impreza?

Outer CV joints usually click or clack on tight turns. Inner CV wear can cause vibration on acceleration. A tired prop shaft or centre bearing often shows up as a droning vibration at steady speeds. Look for flung grease, split boots, or dents on the shaft tubes as visual clues.

Can you drive with a torn CV boot?

It’s risky. A fresh tear might be saved with a new boot and grease if the joint hasn’t run dry or gritty. Once water and dirt get in, the joint wears fast and starts clicking—then a full shaft replacement is usually on the cards. Best move is to repair a torn boot straight away.
