Oil seal for the extended part of the box casing (two wheel drive) — replacement

1. Oil leakage, as a rule, occurs due to wear of the oil seal of the extended part of the casing. Replacing the oil seal is a relatively simple procedure that does not require removing the gearbox from the vehicle.

2. This oil seal is located at the extreme rear of the box, where the driveshaft is connected to it. If a transmission oil leak is detected, raise the vehicle and install vertical supports. If this seal leaks, oil will be found at the front end of the driveshaft. If the oil seal leaks significantly, oil may drip from the rear of the gearbox.

3. Remove the driveshaft (see chapter 8).

4. Using a special puller or screwdriver (see illustration), carefully pry the oil seal out of the socket located at the rear of the gearbox. Do not damage the splines of the secondary shaft of the box.



5. Using a mandrel or a large-diameter socket, insert the oil seal into the socket without allowing it to become distorted. Make sure the seal is completely seated in the socket (see illustration).




6. Lubricate the splines of the automatic transmission output shaft and the outer side of the driveshaft yoke with grease, then install the driveshaft (see chapter 8). Be careful not to damage the lip of the new oil seal.
