9.Remove the snap rings from the end yoke and the shaft yoke. (Refer to Step2)
10.Set the end yoke on the vise so the trunnions of the cross are supported by the jaws of the vise. Hit the end yoke to force the bearing cup out of the end yoke. The bearing cup will only be forced part way out of the end yoke. Note: When hitting the end yoke NEVER hit the area around the hole in ear. Distortion of the hole will make removal of the bearing cup difficult. Figure
11.Repeat step 10 to push the other bearing cup part way out of the end yoke.
12.Fasten one of the bearing cups in the vise. Make sure the jaws of the vise are as close to the end yoke as possible. Hit the end yoke to drive the yoke up off the bearing cup, similar to Step 5.
13.Repeat Step 12 to remove the other bearing cup from the end yoke.
14.The opening between the ears on the end yoke is wider on one side. Remove the cross from the side that has the wider opening.
