Yoke Replacement Double Cardan Universal Joint

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.

Notice: The flange yoke can be replaced without removing bearing cups from the tube yoke or ball support yoke.

1. Remove the bearing cups in the order indicated (1-4). This is the shortest route to the heart of the centering ball system. Perform a close inspection in order to select the correct service method.



2. Mark all of the yokes before disassembly in order to reassemble the yokes and in order to retain the driveshaft balance.

Important: You may not reassemble production universal joints. The production bearing cups do not have bearing retainer grooves. Discard all universal joint parts you remove.

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



4. Place the universal joint so that the lower ear of the yoke is supported on a 30 mm (1 1/8 in) socket.



5. In order to shear the plastic retaining ring on the bearing cup, place the J 9522-5 on the open horizontal bearing cups, and press the lower bearing cup out of the yoke ear.
6. If you have not completely removed the bearing cup, lift the cross and insert the J 9522-5 between the seal and the bearing cup being removed. Continue pressing the bearing cup out of the yoke.
7. Rotate the propeller shaft and press the opposite bearing cup out of the yoke.
8. Inspect the retaining ring grooves for plastic.
9. Inspect each bearing cup bore for burrs or imperfections.
10. Clean the remains of the sheared plastic bearing retainers from the grooves in the yoke.
11. The sheared plastic may prevent the bearing cups from being pressed into place. This condition prevents the bearing retainers from being properly seated.

1. Assemble the flange yoke on the inner cross of the ball tube yoke.
2. Assemble the bearing cup assemblies.



3. Assemble the ball support yoke cross in the flange yoke. Orient the ball support yoke cross with the tube yoke according to the marks that were drawn during disassembly.
4. Inspect all of the trunnions for freedom of rotation.
5. If the trunnions are too tight, strike the flange yoke sharply with a hammer in order to aid in seating the retaining rings.
