Extension Housing Bushing and Rear Seal

Extension Housing Bushing and Rear Seal

Removal

1. Raise the vehicle and disconnect the driveshaft at the transmission. To maintain initial driveshaft balance, mark the rear driveshaft yoke and companion flange so they may be installed in their original positions.






2. When only the rear seal needs replacing, carefully remove with Tool T74P-77248-A or equivalent as shown in Fig. 17.






3. Remove the bushing as shown (Fig. 76). Use the bushing remover Tool T77L-7697-A or equivalent carefully so that the output shaft spline is not damaged.

Installation






1. When installing a new bushing use special Tool T8OL-77034-A or equivalent (Fig. 78).
2. Before installing a new seal, inspect the sealing surface of the universal joint yoke for scores. If scores are found, replace the yoke.
3. Inspect the counterbore of the housing for burrs. Remove burrs with crocus cloth.






4. Install the seal into the housing with Tool T61L7657-A or equivalent (Fig. 22). The seal should be firmly seated in the bore. Coat the inside diameter of the rubber portion of the seal with Multi-Purpose Long-Life Lubricant, C1AZ-19590-B (ESA-M1C75-B) or equivalent lubricant.
