Causes of Axle Shaft Failure

Applications

Tech Note 1: U-Joint
QU40921U Axle Shaft takes universal joints made to Spicer 1350WJ dimensional specifications. The cup diameter for these u-joints is 1-3/16". The 4 cups are grooved to accept Inside C-Clip Snap Rings. The installed Clips fit against the machined inner faces of the axle shaft yokes. The distance between the inside of the axle shaft yoke ears is 2-3/16". For matching u-joints, see TK40712 and QU90007.

Tech Note 2: Length
QU40921U is approximately 17-7/64" long from center of u-joint hole to end. The splined end is 1-5/16" in diameter x 30 splines.

Tech Note 3: Causes of Axle Shaft Failure
Inner axle shaft operating failures are usually a result of either a broken axle u-joint or the axle shaft seal wearing a deep groove through the shaft case hardening. Good preventative maintenance can usually prevent those type of failures. A good number of axle shafts are also wrecked by poor service procedures during u-joint replacement. Over the years I have seen a lot of axle shafts with bent or broken yokes caused by the slam-bang u-joint removal and installation methods. A C-Frame Press with the correct adapters is both the safest and best way to remove or install axle u-joints.
