CV Boot

Product Details:

The part that simultaneously enables the axle to flex while transmitting the driving force is called a drive axle joint, and is also known as a constant velocity (or CV) joint. The CVBootis a ribbed, rubber flexible boot that keeps water and dirt out of the joint and the special grease inside the joint.

Product Details:

CV axle boot are responsible for keeping the joints lubricated and preventing dirt and water from getting in. Unfortunately, this is a part that sometimes fails. If a CV boot tears, grease can leak out and moisture and dirt can get in. If left unattended, it''s only a matter of time before the joint fails from lack of lubrication or corrosion. When that happens, the whole axle may need to be replaced.

CV axle boots often last the life of a vehicle and are not listed among items that need periodic replacement as part of vehicle maintenance. They should, however, be inspected at least once a year, or more often on high-mileage vehicles or ones that see what manufacturers describe as "severe" service, such as off-road use or transportation-industry conditions. Since outer boots are more prone to tears, it is especially important to check these parts.
