2018 Subaru XV CV boots: what they do and when to service them

CV boots are absolutely used on the 2018 Subaru XV. Technical references back this up: the Subaru Factory Service Manual for the 2018 XV (Crosstrek in some markets) details inner and outer constant-velocity joints on the front and rear drive shafts, each protected by rubber boots, and Subaru’s official parts catalogue lists dedicated CV boot kits for this model. Trade catalogues commonly used across Australia and New Zealand also carry front and rear CV boot listings for the 2018 XV, confirming real-world fitment.

On this all-wheel-drive XV, the CV boots are the flexible rubber sleeves that seal grease around the CV joints and keep out water and grit. They bend and flex with steering and suspension travel, so the joints can transfer drive smoothly without vibration. If a boot cracks or splits, grease flings out, contamination gets in, and the joint can start clicking on turns or shuddering under load. Left too long, that means a whole CV shaft instead of an inexpensive boot and grease.

As part of regular servicing, it’s smart to eyeball the boots every 10,000–15,000 kilometres or at each oil change. A quick check on a hoist for perished rubber, loose clamps, or sling marks of dark grease can save a joint. For cars that see gravel roads, beach launches, or lots of full-lock city parking, step up the inspections.

• Typical red flags: grease sprayed inside the wheel, clicking on tight turns, a burning-rubber smell after a drive, or visible cracks in the concertina folds.
• Best practice when replacing: use the specified moly CV grease, fit quality stainless clamps with proper crimping, clean the joint thoroughly, and torque the axle nut to spec.

Boot-only replacement is usually the most cost-effective route if caught early, often a 1–2 hour job per side depending on which joint is affected. Genuine Subaru boots fit nicely and last well, quality aftermarket kits are fine when matched correctly. After any driveline work, a road test for noise and steering feel is a must, and it’s worth checking wheel alignment if the strut or knuckle has been disturbed.

Look after the CV boots, and the XV’s silky AWD manners stay just that—silky, whether it’s the school run or a windy weekend down the coast.

Popular questions about 2018 Subaru XV CV boots

Do the front and rear of a 2018 Subaru XV both have CV boots?
Yes. The XV uses CV joints on both front and rear drive shafts, each sealed by rubber boots. That’s documented in the factory service information and reflected in OEM and aftermarket parts catalogues.

How often should CV boots be inspected on an XV?
Have them checked at every routine service (about every 10,000–15,000 km) or sooner if driving on gravel, through standing water, or doing lots of tight parking. Early detection of a split boot prevents joint damage.

Can a torn CV boot be repaired, or does the whole shaft need replacing?
If the joint is still quiet and free of play, a new boot and fresh grease usually sorts it. If there’s clicking, rust, or pitting inside, replacing the complete CV shaft is the safer long-term fix.
