Caution! When installing the drive shaft, it is necessary to use new nuts for fastening the drive shaft to the rear wheel hub and new bolts for fastening the drive shaft to the rear final drive flange.
Removal
Unscrewing the bolts securing the drive shaft to the rear final drive flange
1. Using a chisel or screwdriver, remove the hub nut cap. Using a punch and hammer, carefully pry the hub nut flange out of the drive shaft groove. Loosen the drive shaft nut and wheel bolts.
2. Raise the rear of the vehicle and support it on stands.
3. Remove the corresponding rear wheel. When removing the left drive shaft, remove the exhaust pipe.
4. Remove the bolts and the mounting plate that secures the drive shaft to the rear final drive flange. Using a soft wire, suspend the drive shaft from the underbody of the vehicle (see fig. Unscrewing the bolts securing the drive shaft to the rear final drive flange).
Caution! Avoid allowing the drive shaft to hang freely, as this may cause the outer constant velocity joint of the drive shaft to become loose. When installing the drive shaft, use new bolts for fastening the inner constant velocity joint of the drive shaft.
5. Loosen the nut that secures the drive shaft to the hub and remove the drive shaft from the hub. If the drive shaft is tightly seated in the hub, use a wooden mallet or a special tool that is bolted to the hub to remove it.
6. Remove the drive shaft from under the vehicle.
Installation

Tightening the nut securing the drive shaft to the hub
Caulking the flange of the drive shaft fastening nut into the groove of the drive shaft
1. Installation is carried out in the reverse order of removal, taking into account the following points.
2. Before installation, lubricate the threads and side surface of the new drive shaft mounting nut with clean engine oil (see Fig. Applying a thin layer of engine oil to both the threads and the side surface of the nut securing the drive shaft to the hub).
3. Install new bolts securing the drive shaft inner joint to the rear final drive flange.
4. Tighten the drive shaft to hub nut to the required torque. Secure the nut from loosening by using a hammer and punch to tap the nut flange into the drive shaft groove (see fig. Tightening the drive shaft fastening nut to the hub, Pinning the flange of the drive shaft fastening nut into the groove of the drive shaft).
