Disassembly

1. Place the driveshaft on a suitable workbench being careful not to damage the tube.

2. Mark the positions of the spiders, the center yoke, and the centering socket yoke as related to the stud yoke which is welded to the front of the driveshaft tube. The spiders must be assembled with the bosses in their original position to provide proper clearance.

3. Remove the snap rings that secure the bearings in the front of the center yoke.

FIG. 2 Partially Pressing Bearing from Center Yoke:

4. Position the U-Joint Tool, T74P-4635-C or equivalent as shown in Fig. 2. Thread the tool clockwise until the bearing protrudes approximately 9.525mm (3/8 inch) out of the yoke.

FIG. 3 Removing Bearing from Center Yoke:

5. Clamp the bearing in a vise and tap on the center yoke as shown in Fig. 3 to free it from the bearing.

FIG. 4 Removing Bearing Cup from Centering Yoke Socket:

6. Lift the two bearing cups from the spider (Fig. 4).

7. Re-position the tool on the yoke and move the remaining bearing in the opposite direction so that it protrudes approximately, 9.525mm (3/8 inch) out of the yoke.

FIG. 3 Removing Bearing from Center Yoke:

8. Clamp the bearing in a vise. Tap on the center yoke to free it from the bearing (Fig. 3).

9. Remove the spider from the center yoke.

FIG. 5 Removing Center Socket Yoke:

10. Pull the centering socket yoke off the center stud (Fig. 5). Remove the rubber seal from the centering ball stud.

11. Remove the snap rings from the center yoke and from the driveshaft yoke.

FIG. 6 Removing Bearing from Rear of Center Yoke:

FIG. 7 Center Yoke Interference Point:

12. Position the U-Joint Tool T74P-4635-C or equivalent, on the driveshaft yoke (Fig. 6) and press the bearing outward until the inside of the center yoke almost contacts the slinger ring at the front of the driveshaft yoke. Pressing beyond this point can distort the slinger ring. The arrow in Fig. 7 illustrates the interference point.

13. Clamp the exposed end of the bearing in a vise and drive on the center yoke with a soft-faced hammer to free it from the bearing.

14. Re-position the tool and press on the spider to remove the opposite bearing.

15. Remove the center yoke from the spider.

16. Remove the spider from the driveshaft yoke in the same manner.

17. Clean all serviceable parts in cleaning solvent. It using a repair kit, install all of the parts supplied in the kit. If the driveshaft is damaged, replace the complete shaft to be assured of a balanced assembly.
