REMOVAL & INSTALLATION
See Figure 1
This seal controls transmission oil leakage around the driveshaft. Continued failure of this seal usually indicates a worn output shaft bushing. If so, there will be signs of the same wear on the driveshaft where it contacts the seal and bushing. The seal is available and is fairly simple to install, with the proper tool.
- Raise and safely support the rear of the vehicle to minimize transmission oil loss when the driveshaft is removed.
- Unbolt the driveshaft from the differential and center support bearing, if equipped. Wrap tape around the bearing cups to keep them in place on the universal joint and slide the shaft out of the transmission.
- Use an small pry tool to carefully pry out the old seal. Be careful not to insert the tool too far into the housing or the bushing will be damaged.
- Use an oil seal installation tool to evenly drive the new seal into the housing. Make sure the tool only contacts the outer metal portion of the seal.
- Install the driveshaft. Torque the universal bearing cup retainer bolts to 15 ft. lbs. (20 Nm).
