Hummer H3. Manual — part 1075

1. Support the propeller shaft in a line horizontal with the table of a press.

2. Mark the propeller shaft in order to show which end connects to the transmission and which

end goes to the rear axle.

3. Disassemble the snap rings by pinching the ends together with a pair of pliers.

4. If the ring does not readily snap out of the groove in the yoke, tap the end of the cup lightly

in order to relieve the pressure from the ring.

NOTE:

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.

10. Remove the cross from the yoke.

11. Remove the remaining universal joint parts from the yoke.

12. If you are replacing the front universal joint, remove the bearing cups in the slip yoke in the

same manner.

13. Inspect the retaining ring grooves for dirt, corrosion or pieces of the old ring.

14. Inspect the bearing cup bores for burrs or imperfections.

15. Clean the retaining ring grooves. Corrosion, dirt, rust or pieces of the old retaining ring may

prevent the bearing cups from pressing into place or prevent the bearing retainers from
properly seating.
