<strong>01. </strong>We’ll show how to swap one axis of a U-joint, but both axes are done the same way when needed. Start by removing both retaining clips with small-nose pliers or a screwdriver. Clamp the axle or driveshaft yoke in a vise between two sockets, one smaller than the joint cap size and one larger. With the vise, push the joint all the way to one side of the yoke. The one cup should come free from the yoke. Pliers may assist here, if needed.
