CV Joints - Joint, boot, grease, clip

This joint allows the axle to move up and down and turn on IRS cars. To check yours, take them off and tear them apart one by one and look for pits. It is not a good idea to mix parts from one joint to the other. If yours are ok, put them back together. Note: When putting them together look at the inner race and you will see a narrow gap between grooves and then a wide gap. Make sure that the narrow groove sits across from a wide groove on the outer race. Lost? Well, if you get it back together and the joint is locked up and the outer race won't move sideways on the inner one then you did it backwards.
