What is a CV boot on a car?
The flexible joint in a CV axle, which accommodates wheel movement, is covered in a rubber boot that is referred to as the CV Boot. This boot serves as a simple dust cover for the CV joint meant to keep out dust and dirt, and keep in the grease that lubricates the CV joint. This may seem like an obscure part, one that you don’t have to worry about.
What happens when a CV axle fails?

How long can you drive with a broken CV boot?
1. Busted Boots. If the problem is just a busted CV boot, you might be able to drive for some time before having work done. However, the longer you drive with the boot busted, the more dirt and grime contaminates the joint and the more grease leaks out.

What Is The CV Joint Axle?
The constant velocity joint (CV) axles of a vehicle are essential parts of the vehicle’s drive train. These axles transfer power from the transmission/transaxle or differentials to the wheels of the vehicle. Besides delivering power, the CV joint of the axle allows for flexibility while driving. This flexibility is needed for all the different angles that are created while turning the vehicle to the right and left, and for traveling over bumps and various road conditions. Front-wheel drive cars, all-wheel drive cars, and some rear-wheel drive vehicles that have independent suspension are equipped with CV joint axles. Some vehicles even employ CV joint axles in the driveline.
How to tell if CV boot is bad?
A grease leak is the first symptom that is most commonly associated with a bad or failing CV boot. Over time, with exposure to the elements a CV boot can become dry or brittle and crack or tear. When a CV boot cracks or tears it will usually leak grease onto the inside of the wheel. Often times the grease can also be flung onto the chassis or other parts on the underside of the vehicle as the CV axle turns. A torn boot can also allow dirt, debris, and moisture to enter the CV joint, which will damage the joint.
