Parts for your 2020 Subaru Legacy-Cv boots

2020 Subaru Legacy CV boots: purpose and practical servicing advice

Based on Subaru technical sources—the 2020 Legacy/BT-chassis Service Manual (Drive Shaft/Front & Rear Axle sections) and the Subaru Genuine Parts Catalogue listing front and rear driveshaft boot kits—CV boots are absolutely fitted and relevant on the 2020 Subaru Legacy with Symmetrical All-Wheel Drive.

On this model, CV boots are the flexible rubber bellows that seal each constant velocity (CV) joint on the front and rear driveshafts. Their job is simple but critical: keep special moly CV grease in, and water, dust, and road grit out. When a boot cracks or splits, grease gets flung out and contaminants get in, and that’s when joints wear fast and start clicking on turns or vibrating under load.

As part of regular servicing, it’s wise to have the CV boots inspected at each scheduled service interval. A quick look under the car for wet sling marks around the inner wheel area, small cracks in the bellows, or grease buildup on the control arms tells a big story. In Aussie and Kiwi conditions—heat, UV, gravel roads, and the odd water crossing—boots can age quicker than expected.

If a boot is only perished or just starting to weep, a boot-only repair with fresh grease can save a pricey joint. If the boot has been torn for a while and the joint has started clicking, a full CV joint or complete shaft replacement is usually the go. Always use the correct CV grease specified by Subaru and have all fasteners tightened to factory torque specs.

Handy signs it’s time to act:

• Grease splatter on the inside of the wheel or underbody
• Cracks in the boot bellows or visible splits
• Clicking on tight turns, or a shudder on take-off

Practical tips for owners:

1. Ask for a CV boot check at every routine service interval.
2. After a beach run or muddy trip, rinse the underbody and have the boots checked for grit or damage.
3. Fix small boot issues early—waiting can turn a simple boot job into a full driveshaft replacement.

Look after the CV boots on a 2020 Legacy and the AWD driveline will stay quiet, smooth, and reliable for the long haul.

Popular questions

Does the 2020 Subaru Legacy have CV boots?
Yes. The 2020 Legacy uses CV joints and rubber CV boots on both front and rear driveshafts as part of Subaru’s Symmetrical AWD system. The boots protect the joints by sealing in grease and keeping out water and grit.

How often should the CV boots be inspected?
Have them checked at every scheduled service. In Australia and New Zealand, UV, heat, and unsealed roads can accelerate boot ageing, so a quick visual check each service is cheap insurance against joint damage.

Can they drive with a torn CV boot?
Short answer: not ideal. A torn boot quickly leads to grease loss and contamination, which can destroy the joint. If a tear is found early, a boot and grease service may be enough. If there’s clicking on turns, the joint may already need replacement.
