Tech Note 1: U-Joint Specs
QU20029 yoke is made to take universal joints made to special Spicer 1330F series external snap ring universal joint specifications. The u-joint cup diameter for the driveshaft yoke should be 1-1/16". The u-joint cup diameter for the pinion yoke should be 1-1/8" and the overall width of the universal joint should be 3-5/8". See TK40723 and QU40776 External Snap Ring Universal Joints.

Tech Note 2: Product Note
This 31 spline yoke has a length through the hole of 1-17/64" so it will NOT fit later 10.25" and all 10.5" rear axles. See QU20101 for a long spline Pinion Yoke.

Tech Note 3: Matching Parts
When replacing an old pinion yoke, always replace the pinion seal, pinion nut, and crush sleeve. Replace the u-joint strap kit and outer pinion slinger as needed. Order these matching parts separately:
