2020 Subaru XV CV boots: what they do, why they matter, and when to replace them

CV boots are absolutely relevant to the 2020 Subaru XV. Subaru’s Global Service Manual for the GT/GT7 XV (MY2018–2020) lists front and rear drive shaft boots under the Front Axle and Rear Axle sections, including inspection and replacement procedures. The Subaru FAST parts catalogue also shows separate inner/outer boot part numbers for both front and rear shafts. In short, the 2020 Subaru XV is fitted with CV boots on every drive shaft.

This XV runs Subaru’s Symmetrical AWD with independent suspension, which relies on constant velocity joints to transfer torque smoothly while the wheels steer and move through their travel. Each CV joint is sealed by a flexible rubber boot packed with grease. That boot keeps grease in and road grit, mud and water out. If the boot splits, the grease gets flung out and contaminants get in, wearing the joint fast and leading to clicks on turns, vibration, or even joint failure.

For owners who see a bit of gravel, beach launches, or the occasional track, CV boot checks are a smart routine. Subaru’s maintenance schedule calls for periodic inspection of driveshaft boots. A quick look during each service saves a lot of grief later.

• What to look for: a ring of grease on the inside of the rim or guard, small cracks in the rubber, loose or rusty clamps, or a weeping boot after off-road or flood driving.
• If damage is minor: a boot-only replacement with fresh moly grease and new clamps is usually all that’s needed.
• If the joint has run dry or gritty: a complete shaft or joint replacement may be more cost-effective.

When replacing a CV boot on a 2020 XV, a competent tech will clean the joint thoroughly, repack with the specified grease, fit the correct inner/outer boot (they differ), and crimp new stainless clamps to spec. It’s also wise to check the other boots at the same visit, torque the axle nut to the service manual specification, and road test for any residual noise or vibration. Genuine or high-quality aftermarket boots last longer, especially in hot climates or with frequent rough-road use.

1. Inspect CV boots at regular service intervals or after heavy off-road use.
2. Act early if grease spray or cracking appears—saving the joint saves money.
3. Use the right grease, boot type and clamp tools to avoid future leaks.

Popular questions about 2020 Subaru XV CV boots

How long do CV boots last on a 2020 Subaru XV?
In normal suburban driving, CV boots can last well over 100,000 km. Heat, UV, and frequent articulation from rough roads shorten their life. Regular inspections during scheduled services help catch ageing before it becomes a joint problem.

What are the signs a CV boot has failed on a 2020 XV?
Look for a flung ring of dark grease on the inner wheel, control arms or undertray, small tears or splits in the boot, or loose clamps. If the joint has already been contaminated, the driver may notice clicking on turns, shudder on acceleration, or vibration at speed.

Can a torn CV boot be replaced without changing the entire axle?
Yes—if the joint hasn’t been run dry or gritty for long. A boot-only repair involves cleaning and repacking the CV with the specified grease and fitting new clamps. If there’s wear or pitting, a complete shaft can be the better value and more reliable fix.
