Before installing the gearbox, thoroughly clean the axle beam from oil.
1. Place a sealing gasket on the mating surface, insert the reducer into the beam and fasten it with bolts. Lubricate the threads of the bolts with sealant. Thoroughly degrease the bolts and holes in the beam before applying the sealant. Attach the cardan shaft to the gearbox. Install axle shafts and brake drums.
2. Install the wheel with the tire and screw, without tightening, the wheel bolts. With both wheels in place, remove the stands and lower the car; then tighten the wheel bolts with a torque wrench.
3. Fill the axle beam with oil through the oil filling hole, having previously cleaned and screwed the magnetic drain plug into the beam.
