Tools Required

Notice: Never clamp propeller shaft tubing in a vise. Clamping propeller shaft tubing in a vise 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.

1. Remove the propeller shaft. Refer to Front Propeller Shaft Replacement or Rear Propeller Shaft Replacement .
2. Support the propeller shaft in a line horizontal with the table of a press.
3. Mark the propeller shaft in order to show which end connects to the transmission or transfer case and which end connects to the rear or front axle.



4. Remove the snap rings.

•	Pinch the ends of the snap ring together with a pair of pliers.

•	If a snap ring does not readily snap out of the groove in the yoke, tap the end of the bearing cup lightly in order to relieve the pressure from the ring.




5. Place the universal joint so that the lower ear of the yoke is supported on a 30 mm (11/8 in) socket.
6. Press the lower bearing cup out of the yoke ear. Use the J 9522-3 .



7. If the bearing cup is not completely removed, do the following:

7.1.	Lift the cross and insert the J 9522-5 between the seal and the bearing cup.

7.2.	Continue pressing the bearing cup out of the yoke.

8. Rotate the propeller shaft and press the opposite bearing cup out of the yoke.



9. Remove the cross from the yoke.
10. Remove the remaining universal joint parts from the yoke.
11. If you are replacing the front universal joint (rear axle only), remove the bearing cups in the slip yoke in the same manner.
12. Inspect the retaining ring grooves for dirt, corrosion, or pieces of the old ring.
13. Inspect the bearing cup bores for burrs or imperfections.

Important: Corrosion or dirt may prevent the bearing cup installation and may prohibit the proper seating of the bearing retainers.

14. Clean the retaining ring grooves.

1. Remove the bearing cups from the new universal joint journals.
2. Coat the needle bearings in the bearing cups with a thin layer of the grease that is present on the journal. Use your finger to apply the grease.



3. Install one bearing cup part way into one side of the yoke.
4. Turn the yoke ear towards the bottom.
5. Install the cross into the yoke so that the trunnion 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. Install the opposite bearing cup part way into the yoke ear.
8. Make sure that the trunnions are started straight and true into both bearing cups.

Important: If the bearing cup seems to bind or hang-up, stop pressing. Check the needle bearings for misalignment in the bearing cup.

9. Press the opposite bearing cup into the yoke ear.

•	Work the cross all the time.

•	Check for free unbinding movement of the trunnions in the bearing cups.

•	Press the bearing cup into the yoke until the bearing retainer groove is visible over the top of the bearing cup.




10. Install the bearing retainer in the retainer groove.

•	Continue pressing until you can snap both retainers into place.

•	A small amount of chassis grease may help the snap ring seat in the bearing cup groove.




11. If the retainer does not seat, spring the yoke slightly with a firm blow from a dead blow hammer.
12. Install the propeller shaft. Refer to Front Propeller Shaft Replacement or Rear Propeller Shaft Replacement .
