Description
This assembly features Neoprene boots with additional bellows to resist stress and ozone cracking, a common cause of boot failure. The splines are precision rolled for proper fit, and the transmission seal diameter is machined after heat treatment for long seal life. It also includes a new axle retaining nut for hassle-free installation. All shafts are individually tested for straightness and vibration-free performance.
