What is a C.V.J. (constant velocity joint) and why does it click when turning?
Constant velocity joints are a type of universal joint which allow the drive axles to rotate and transmit torque to the wheels in multiple planes without binding. Typically the protective rubber boot will tear or split and allow the lubricant to escape and allow contaminents to enter the joint. As the rollers in the joint pass over the worn areas in the grooves of the outside housing, they click. The most effective way to fix a worn C.V.J. is replacement with a remanufactured unit.
