Shop now for Pinion Yokes and Pinion Seals to fit 1999-2016 Ford F250 and F350 4x4 trucks with Sterling 10.5" Rear Axles. Great selection. In stock. Quick shipping.
Ford used two types of u-joint coupling at the 10.50" rear axle. Most models especially in later years will have a round companion flange on the axle which bolts to a driveshaft flange yoke, however some vehicles use a Pinion Yoke which directly connects to the driveshaft universal joint. Either style will need replacement when the seal surface is grooved, but it is very rare to replace a companion flange for any other reason. In contrast, a bad u-joint will often wreck a pinion end yoke.
