CV Boots have a very important function of sealing off the constant velocity (CV) joints from external elements such as dirt and water etc that should not be allowed in. Due to effects such as oxidation of the boots material brought about by oil and grease, the boots should always be washed with soap and water. Since the outer CV Boot works in line with the pivoting motion that follows the steering action of the front hub, the latter should be checked often because it usually wears out faster. They should be checked for signs of tears or cracks, and loose clamps; if the boots are cracked, or if lubricant is leaking, they should be replaced.
