In preparation for the overhaul of the car, all components and assemblies are dismantled, disassembled and defective from it. Such foresight, as practice has shown, is never superfluous. Units that did not show any signs of malfunctions during operation, removed and disassembled in detail, sometimes turned out to be extremely worn out.

Instructions
Step 1
The car from which it is planned to dismantle the driving rear axle is placed on an inspection pit or lift. From below, the propeller shaft mounting bolts are unscrewed and the parking brake cable clip is disconnected. From the brake force regulator, the hose of the hydraulic brake drive is unscrewed to the rear axle.
Step 2
Disconnect from the bridge: jet rods (one transverse and two longitudinal), shock absorbers, braking force regulator thrust. Then the car, or the back of its body, is lifted and the rear axle rolls out.
Step 3
Now you can start to disassemble it in detail. First of all, wheels with disks are dismantled from the bridge, and rigid supports are substituted under the beam. Then the brake drums are removed from both sides and the mechanisms located under them are disassembled. Through the hole in the flange of the axle shaft, four bolts of its fastening to the "stocking" are unscrewed, and with the help of an impact puller it is pressed out of its regular place. A similar procedure is carried out on the opposite side of the bridge.
Step 4
After removing the axle shafts, the eight bolts securing the main hypoid gear housing to the axle are unscrewed, then the gearbox assembly is dismantled and placed on the workbench.
Step 5
In cases where there are serious reasons for the reliability of the extracted unit, it is strongly recommended to entrust its repair to only a highly qualified specialist. If the disassembly of the gearbox does not pose any difficulties for anyone, then the assembly, and especially the subsequent adjustment of the main gear, is a very complicated procedure, and requires the use of special equipment.
Step 6
Even a harmless tightening of the “shank” flange nut changes the adjustment parameters to such an extent that it will inevitably provoke a failure of the rear axle gearbox for a very short mileage.
