Outer Joint
WARNING: This page is about a different car, the 2003 Chevrolet Corvette and 2002 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The outer joints are of the Rzeppa joint design. The splined shaft end which mates with the knuckle and hub assembly, incorporates a helical spline to assure a tight, press-type fit. This design assures that no end play will exist between the hub bearing and the axle shaft assembly for added durability and reduced bearing noise.
