The Constant-Velocity Joint

June 8th, 2011

This is something kind of hard to explain; are you ready? The CV Joint is an application that allows a drive shaft to transfer power through something called a variable angle at constant rotational speed without an appreciable increase in friction or play. It’s mainly used in cars that use front-wheel drive – so cars like the Honda Civic with OE Honda wheels… or Honda Civic wheels.

The rear-wheel drive cars with the independent rear suspension will usually use the same CV Joints, but these are at the ends of the rear axle halfshafts, and increasingly use them on the propshafts. The joints are typically protected by some sort of rubber boot called a CV gaiter. When there’s cracks and splits in the boot, this means that the joint will most likely corrode and a new joint has to be fitted if the original joint isn’t removed early enough.

Do you get it?
