The CV boots are typically located on the ends of a vehicle’s drive shaft/axles. They’re on both the inner and outer drive shafts, connecting the transmission to the wheels.
CV boots are often found on front-wheel-drive axle shafts and rear-wheel shafts in all-wheel drive and some rear-wheel drive vehicles.
The CV boots protect the vehicle’s CV joints, which connect the axles to the wheels and allow for smooth, constant-velocity rotation. They keep dirt, water, debris, and other contaminants from damaging or corroding the CV joints. They’re usually made of flexible, durable rubber.
Tips on How to Access the CV Boots
The CV boots can only be accessed through the vehicle’s undercarriage. If you need to inspect or replace them, you’ll need to lift your vehicle with jack stands and keep it still with wheel chocks and the spindle and strut will need to be disconnected.
The big nut on the end of the CV axle where it goes through the hub will need to be removed and you may need a puller to force the splined CV joint out of the wheel hub.
It’s a pretty big job. Even bigger if you haven’t done it before, so be advised.
