The CV Boots are important in ensuring that dirt, water, and foreign materials do not get into the constant velocity (CV) joints and destroy them. Washing the boots with soap and water is recommended to prevent the premature deterioration of the material of the boots by the effects of oil and grease. The outer CV Boot is likely to be damaged much sooner because of its continuous pivoting movement that follows the steering movement of the front hub and it should be checked regularly. One should also check the boots against tearing, cracks and loose clamps by bending them with fingers to reveal any cracks or dripping grease; any signs of damage or grease leakage should warrant a replacement.
