What is a CV Boot?
Front wheel drive cars and 4 wheel drives use flexible axle shafts with Constant Velocity joints or CV s for short. The CV joints allow the axle shafts to spin the front wheels while moving up or down over bumps or turning corners. The CV joint has a protective rubber boot that keeps grease for lubrication in, and dirt and water out. When the rubber boot breaks the CV joint loses grease and starts to “click,” especially during cornering. The broken boot should be replaced as soon as it is noticed to help avoid costly repairs.
