2017 Subaru XV CV Joint: purpose, care, and replacement tips

CV joints are absolutely fitted to the 2017 Subaru XV (also known as GP/GP7 series). Technical references including the Subaru Workshop Manual (Front Axle/Drive Shaft section for Impreza/XV GP), the Subaru Parts Catalogue for 2017 XV front and rear axle shafts, and independent manuals covering Impreza/XV 2012–2017 all specify inner DOJ-type and outer fixed ball-type constant velocity joints on the front shafts, with CV-jointed halfshafts at the rear as part of Subaru’s Symmetrical AWD layout.

On this XV, the CV joint’s job is to transfer torque smoothly from the transaxle to the wheels through suspension movement and steering angle, without vibration. The inner DOJ handles plunge and angle changes as the suspension works, while the outer joint keeps power delivery even at full steering lock. At the rear, CV-jointed halfshafts send drive from the rear differential to each wheel through bumps and body roll. When everything’s happy, the car feels planted and quiet, with no shudders on take-off or tight turns.

As part of regular servicing, it’s worth giving the CV boots and joints a proper look. The boots keep special moly grease inside and road grime out, once a boot splits, the grease leaves, grit gets in, and wear escalates quickly.

• Inspect every service: look for cracked, perished, oily, or flung-grease boots, check clamps for looseness.
• Listen on test drive: clicking on tight, low-speed turns points to outer joint wear, shudder or vibration on acceleration often suggests inner joint play.
• Fix early: a fresh boot and grease can save a good joint if caught promptly, a noisy joint usually needs replacement.

When replacement’s on the cards, many workshops fit a complete driveshaft assembly for reliability and time savings. If swapping just a joint or boot, use the specified CV grease volume and new clamps, and clean meticulously. Always fit a new axle nut and stake it, and follow the workshop manual for torque and alignment precautions. After-market shafts can work fine, but genuine-spec parts often last longer, especially for mixed city–country driving across Aussie and Kiwi roads.

• Driving style and environment matter: frequent full-lock manoeuvres, torn gravel, or deep water crossings shorten CV life.
• As a rule of thumb, good CVs and boots can last well past 150,000 km, but inspect them at every service interval.

Popular question: What are the tell-tale signs of a worn CV joint on a 2017 Subaru XV?

Classic symptoms include a rhythmic clicking or clacking when turning tightly at low speed, especially under light throttle. That’s often the outer joint. A shimmy or vibration on acceleration that eases off when coasting can indicate wear in the inner DOJ. Grease splatter around the inside of the wheel or lower control arm points to a split boot that needs urgent attention.

Popular question: Should both CV joints or shafts be replaced at the same time?

Not always. If only one side is noisy or a single boot has failed, the repair can be limited to that side. However, on higher-kilometre vehicles or when both sides show similar wear, doing both front shafts together can save labour and keep driveline balance consistent. A proper inspection will guide the call.

Popular question: Can a torn CV boot be repaired, or is a full shaft replacement required?

If the joint hasn’t run dry or ingested grit for long, a new boot, correct grease, and fresh clamps are a perfectly sound fix. If there’s clicking, blueing, pitting, or excessive play, replacing the joint—or the complete driveshaft—will give a longer-lasting result and reduce the chance of repeat work.
