The procedure for removing the rear axle gearbox oil seal
1. Reducer; 2, 3. Bearing cages of the drive gear of the final drive; 4. Adjusting washer; 5. Oil seal; 6. Flange; 7. Washer; 8. Self-clamping nut
Removal and installation
1. Raise the car, drain the oil from the gearbox.
2. Apply orientation marks and disconnect the rear driveshaft.
3. Measure the moment of resistance to turning the drive gear of the main gear, which should be 0.4–0.5 Nm, this moment should be maintained during assembly.
4. While holding the flange, unscrew the nut and remove the washer.
5. Get a flange of a leading gear wheel, pry off and get an epiploon of a reducer.
6. Assembly is carried out in the reverse order.
7. Press a new oil seal with a mandrel so that the surface of the oil seal is flush with the plane of the gearbox.
8. Tighten the flange nut, checking the resistance torque of the drive gear, the final tightening torque of the nut should be 190–250 Nm.
