It uses a 2.500-inch, 10-spline bore and a half-round strap-style yoke to secure the u-joint. The hub is machined for a speedometer gear, and it includes a slinger for protection. You typically replace this yoke when the splines are worn, the yoke ears are damaged, or the speedometer gear hub fails.
