Applications

Tech Note 1: Matching U-Joints
QU40389 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: Common Axle Shaft Failures
Outer axle shaft operating failures are usually a result of either a broken axle u-joint or a dry spindle bearing. 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 QT1065M C-Frame Press with the correct adapters is both the safest and best way to remove or install axle u-joints.

Tech Note 3: 1991 Axle Shafts
Dana lists odd ball axle shafts for 1991 3/4 tons with axle tag number 610360-2. Dodge parts books do not show this axle so I suspect it was a limited production item for a specialty off road or export application.
