Abstract: A hand tool for assembling and disassembling constant velocity joints of varing size is disclosed. The hand tool includes a handle portion connected to one end of a generally C-shpaed body portion. The other end of the C-shaped body portion includes a projection extending outwardly in general longitudinal alignment with the handle portion. The projection is adapted to receive one of a plurality of differently sized end pieces thereon. Each of the end pieces is formed generally in the shape of a hollow cylinder having one closed end. The inner diameters of all of the end pieces are equal to each other, and all are slightly larger than the outer diameter of the projection. The outer diameters of the end pieces are all different, corresponding to a constant velocity joint having a different size. An O-ring is provided for selectively retaining one of the end pieces on the projection for use with a given size of constant velocity joint. Additonally, an enlarged hook portion is formed on the C-shaped body portion.
