Tools Required

Notice: Whenever the propeller shaft slip yoke is replaced, the adjoining universal joint must also be replaced. Otherwise, damage to the slip yoke may result.

1. Remove the propeller shaft. Refer to One-Piece Propeller Shaft Replacement , Two-Piece Propeller Shaft Replacement , or Three-Piece Propeller Shaft Replacement .

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.

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 and which end connects to the rear axle.



4. Remove the snap rings, if equipped.

•	Pinch the ends of the snap ring together with pliers and remove the snap ring from the yoke.

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




5. Place the universal joint so that the lower ear of the propeller shaft yoke is supported on a 30 mm (11/8 in) socket.
6. Press the lower bearing cup out of the propeller shaft yoke ear. This will also remove the plastic retaining ring on propeller shafts equipped with the production nylon injected ring type universal joint. 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 propeller shaft yoke.

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




Important: Production universal joints cannot be reassembled. There are no bearing retainer grooves in production bearing cups. Discard all production universal joint parts that have been removed.

9. Remove the cross and the slip yoke from the propeller shaft yoke.

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

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

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. Apply the grease with your finger.



3. Install one bearing cup partway into one side of the propeller shaft yoke.
4. Turn the propeller shaft yoke ear towards the bottom.
5. Install the cross into the propeller shaft 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 propeller shaft yoke until it is flush with the yoke ear.
7. Install the opposite bearing cup partway into the propeller shaft yoke ear.
8. Make sure that the trunnions are started straight and true into both bearing cups.
9. Press the opposite bearing cup into the propeller shaft yoke ear.

•	Pivot the cross while installing the bearing caps.

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

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

•	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. Repeat the installation procedure to install the universal joint to the slip yoke.
