J9522-5 Universal Joint Bearing Spacer Remover
1. Support the propeller shaft in a line horizontal with the table of a press.
NOTICE: Never clamp propeller shaft tubing in a vise. Clamping could dent or deform the tube causing an imbalance or unsafe condition.
Always clamp on one of the yokes and support the shaft horizontally. Avoid damaging the slip yoke sealing surface. Nicks may damage the
bushing or cut the lip seal.
2. Mark the propeller shaft as to which end is the transmission end and which end goes to the rear axle.
3. Place the universal joint so that the lower ear of the yoke is supported on a 30 mm (11 1/8 inch) socket,
4. In order to shear the plastic retaining ring on the bearing cup, place J9522-3 on the open horizontal bearing cups and press the lower bearing cup
out of the yoke ear.
5. If the bearing cup is not completely runnion seats freely into the bearing cup.
6. With the trunnion seated in the bearing cup press the bearing cup into the yoke until it is flush with the yoke ear.
7. Rotate the propeller shaft and press the opposite bearing cup out of the yoke
8. Mark the orientation of the slip yoke to the tube for proper reassembly.
9. Remove the cross from the yoke.
10. Remove the remaining universal joint parts from the yoke. If you are replacing the front universal joint, remove the bearing cups in the slip yoke in
the same manner.
11. Inspect the retaining ring grooves for plastic.
12. Inspect the bearing cup bores in the yoke ears for burrs or imperfections.
13. Clean the remains of the sheared plastic bearing retainers from the grooves in the yoke.
14. The sheared plastic may prevent the bearing cups from being pressed into place and thus prevent the bearing retainers from being properly seated.
