Parts for your 2019 Subaru Xv-Cv boots

2019 Subaru XV CV boots — purpose, care, and when to replace

Referencing technical sources: Subaru’s factory Service Manual (STIS) for the 2018–2020 Crosstrek/XV in the Driveline/Axle section, along with the Subaru Genuine Parts catalogue (FAST, Group 28 – Drive Shaft), specify inner and outer constant velocity joints and rubber boot kits for both front and rear drive shafts on this model. Major aftermarket catalogues that service Australia and New Zealand also list dedicated CV boot kits for the 2019 XV. Put simply, the 2019 Subaru XV is fitted with CV boots front and rear, and they’re an essential wear component in the AWD driveline.

On the 2019 Subaru XV, CV boots do the quiet, messy job of keeping high-moly grease in and grit, water, and road grime out of the CV joints. They’re flexible rubber bellows that move with the steering and suspension, sealing the joint as the axle changes angle. Front outer boots cop the most flex from steering, while inner fronts and the rears work hard with suspension travel in Subaru’s full-time AWD system.

There’s no set replacement interval, but smart servicing in Australia and New Zealand means inspecting the boots at every service (around 10,000–15,000 km). A quick torch check for splits, cracking, loose clamps, or grease sling on the inside of the wheel or undertray can save a CV joint. Catching a minor weep early usually means a simple boot-and-grease job, leaving a torn boot can wash the grease out and dust in, leading to joint wear and that tell-tale clicking on full lock.

• Common signs they need attention:
  • Grease sprayed around the inner rim, strut, or underbody
  • Cracks in the rubber or a boot gone hard and shiny
  • Clicking or knocking when turning, especially under throttle

When replacing, use quality boots designed for the XV rather than universal stretch boots if longevity matters. Proper stainless clamps, fresh high-moly CV grease, and new clips are a must. A workshop will clean the joint, repack it, slide on the new boot, and clamp to spec, if the joint’s already noisy or gritty, a complete shaft may be the better call. DIYers should allow time, mind the axle nut torque and alignment, and keep everything spotless—grit is the enemy.

Regular boot checks protect the CV joints, keep the XV’s AWD smooth and quiet, and help it sail through a WOF or rego inspection without surprises.

Popular questions about 2019 Subaru XV CV boots

Does the 2019 Subaru XV have CV boots on both axles?
Yes. The XV uses CV joints and rubber boots on the front and rear drive shafts. Front outers see the most steering movement, rears work constantly with suspension travel in AWD use.

How often should CV boots be checked or replaced?
Check them at every regular service (roughly 10,000–15,000 km). Replace a boot as soon as it’s cracked, leaking, or split. There’s no fixed kilometre interval—condition is everything.

Can a split CV boot be temporarily patched?
Short-term patches or tape are risky and usually don’t last. If a boot has split, it should be replaced promptly and the joint cleaned and regreased. If the joint is already noisy, consider a complete shaft.
