Parts for your 2014 Subaru Impreza-Driveshafts

2014 Subaru Impreza driveshafts — what they do and how to look after them

Driveshafts are absolutely relevant on the 2014 Subaru Impreza. Technical sources such as the Subaru Impreza (GJ/GP, MY2012–2016) Factory Service Manual, the Subaru Electronic Parts Catalogue, and widely used workshop references identify front CV driveshafts (left and right) plus a propeller shaft and rear driveshafts on Symmetrical AWD models. Australian and New Zealand variants of the 2014 Impreza are AWD as standard, so the car uses multiple shafts to send torque from the transmission to the front and rear wheels.

On this Impreza, the front CV driveshafts transfer power from the transaxle to each front wheel whilst allowing full steering and suspension movement. The propeller shaft runs down the centre to the rear differential, and the rear driveshafts (CV axles) deliver torque to each rear wheel. Together, they’re the backbone of Subaru’s sure-footed feel and traction on wet or loose roads.

Good servicing habits keep these parts quiet and reliable. At regular services, a quick visual of the CV boots is essential. Any split boot or flung grease needs attention pronto—leaving it will let grit in, wear the CV joints, and turn a simple boot job into a complete axle replacement. Listen for clicking on tight low-speed turns (fronts), shudder on take-off, or a droning/whirring that changes with road speed (could be prop shaft centre support bearing or rear CVs). Vibrations under load can also point to worn joints or an out-of-balance propeller shaft.

If a driveshaft needs replacing, quality new or reconditioned CV axles are the go. Always renew the axle nut, seals where specified, and torque everything to factory spec. Aftermarket options can be cost-effective, but OE-style boots and grease are worth it for longevity. The propeller shaft on these models uses non-serviceable universal joints, if there’s play or a failing centre bearing, the assembly is typically replaced as a unit.

A few easy tips help them last:

• Inspect CV boots every service or 10,000–15,000 km.
• Fix leaks near the transaxle or diff that can soften boots.
• Avoid harsh clutch dumps or shock loads that stress joints.
• After suspension or hub work, ensure splines are clean and the axle nut is torqued correctly.

Popular questions about 2014 Subaru Impreza driveshafts

How long do the CV driveshafts typically last?
With intact boots and normal use, many see well over 150,000–200,000 km. Harsh driving, lifted suspension, or torn boots shorten life. Regular inspections keep them going much longer by catching boot damage early.

Can a bad driveshaft cause vibration at highway speeds?
Yes. A worn CV joint, damaged propeller shaft centre bearing, or imbalance can cause vibration that gets worse with speed. Rule out tyres and wheel balance first, then inspect shafts and joints for play or leaking grease.

Is it safe to keep driving with a clicking CV joint?
It’ll usually get progressively worse. While the car may remain drivable for a time, the joint can fail and leave the vehicle immobile. Replacing the affected axle sooner avoids collateral damage and tow bills.
