A: 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 and durable rubber.
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.
If you’re accessing the CV boots simply for inspection rather than replacement, take the chance to clean them while you can reach them. Also, don’t stop at a visual check. Pull and twist the CV boots to test their durability and condition.
