2. Do not loosen both the left and right flange shaft mounting bolts at the same time, as it will be difficult to install the bolts if the differential gears are turned.
3. To replace the seals, it is necessary to remove the corresponding flange shaft (see illustration), having previously separated the drive shaft from it. You can hold the flange shaft from turning by the opposite wheel or by using a lever inserted between two bolts screwed into the flange.
9.3. Unscrewing/tightening the left flange shaft mounting bolt
4. Use a suitable hook to remove the seal and a suitable mandrel to press it on. Before installation, lightly lubricate the outer surface of the seal with transmission oil and fill the inner groove of the seal halfway with G 052 128 grease. Press the seals until they stop, without allowing them to twist.
5. Use a new cone bolt to secure the flange shaft.
