Removal

1. Raise the vehicle on a hoist. Refer to Section 00-02. Disconnect the driveshaft at the transmission. To maintain driveline balance, mark the rear driveshaft yoke and axle companion flange so the driveshaft can be installed in its original position. Refer to Section 05-01.

2. When only the rear seal needs replacing, carefully remove it with Seal Remover T74P-77248-A.

3. Remove the bushing. Use the Extension Housing Bushing Remover T77L-7697-A carefully so that the output shaft spline is not damaged.

Installation

1. When installing a new bushing, use Extension Housing Bushing Replacer T80L-77034-A.

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 Extension Housing Seal Replacer T61L-7657-A. The seal should be firmly seated in the bore. Coat the inside diameter of the rubber portion of the seal with Premium Long Life Grease XG-1-C (ESA-M1C75-B) or equivalent.

5. Install the driveshaft so that the index marks, made during removal are correctly aligned. Refer to Section 05-01.

   NOTE: Lubricate yoke splines with Premium Long Life Grease XG-1-C (ESA-M1C75-B) or equivalent.
