Abstract
A constant velocity universal joint has replaceable inserts for ball grooves. The inserts and balls can be removed and replaced with new ones as needed, without the requirement of replacing the entire universal joint. The inserts can be made from solid blocks which are bored and cut in half to form inserts for the inner and outer races of the universal joint. The inserts can be machined and matched in particular ways to form a variety of designs of ball grooves.
