CV Boots Explained

courtesy of Bob, The Auto Answer Man

Hi Bob,
I have a 1991 Honda Accord. When it was in for service last month the tech stated that the CV boots were cracked. Do these need to be replaced soon? What does a CV boot do? How can I test the severity of the CV boot crack?

The Constant Velocity boot protects the CV joint. The CV joint is essentially the drive axle on front wheel drive cars. There really is no "severity" in cracked boots. They are either cracked or not. When they get cracked they let the grease and lubricants out of the joint and dirt and grit get in. This will eventually wear out the CV joint and cause it to fail.
Good Luck!
Drive Safely!
