When Do You Need to Replace a Drive-Axle Boot?

Posted on January 9, 2023 in Maintenance

Your axles transfer power from the transmission (in a front-wheel-drive setup) or the differential (in a rear-wheel-drive system) to the wheels so your car can move. The drive-axle boot protects that joint.

How serious is a leaking CV boot?

If the boot becomes damaged, the grease lubricating the joint can leak out. This can also open the door for dirt and debris to get inside. The dirt will mix with grease inside the joint and, eventually, cause the joint to fall apart. If your axles are failing, you'll still technically be able to drive your car.

Is it safe to drive?

If your axles are failing, you should not continue driving. If your axle fails completely while you're driving, you'll likely lose control of the car— and risk causing an accident or crashing. With those risks in mind, we recommend having the problem diagnosed and repaired as soon as possible.

Getting a Replacement

Usually, when an axle starts to deteriorate, you’ll notice:

bumping, clicking, or grinding noises as you're turning, or
excessive shaking and vibrating as you accelerate.

If you experience either of those symptoms, it's time to call the mechanic for a repair. If left unaddressed, the wheel bearings will seize and the wheel itself can come off and you'll lose control of the car.
