Attention! When installing the rear final drive, it is necessary to use new nuts for fastening the rear of the driveshaft, bolts for fastening the drive shaft and nuts for fastening the rear final drive housing.
Removing
1. Raise the rear of the car and secure it on stands. Remove rear wheels. If necessary, drain the oil from the rear final drive housing.
2. Using paint, apply alignment marks to the driveshaft flexible coupling and rear final drive flange. Unscrew the nuts and bolts securing the propeller shaft flexible coupling to the rear final drive flange. When installing, new nuts must be used.
3. Unscrew the bolts securing the inner joint of the right drive shaft to the rear final drive flange, remove the mounting plate and, using a soft wire, hang the drive shaft to the bottom of the car.
Attention! Eliminate the possibility of free sagging of the drive shaft, as this can cause the outer joint of the drive shaft to equal angular velocities. When installing the drive shaft, it is necessary to use new bolts for fastening the inner joint of the drive shaft.
4. Disconnect the left drive shaft from the rear final drive in the same way.
5. On models with ABS, disconnect the rear wheel sensor electrical connector. Remove the electrical wires from the mounting brackets so that the sensor can be removed together with the rear final drive.
6. Support the rear final drive with a jack through a block of wood.
7. Unscrew nuts and take out two bolts of fastening of a back part of the main transfer. Unscrew the nut and remove the bolt securing the front of the final drive. When installing the rear final drive, new nuts must be used.
8. Being careful, lower the rear final drive and remove it from under the vehicle. Mark the location and remove the washers and rubber mounts from the rear final drive front mount. Check the condition of the rubber mounts and replace if necessary.
Installation
1. Align the flange of the rear final drive with the flexible coupling of the propeller shaft in accordance with the marks made before removal.
2. Check the correct installation of the rubber supports and washers and install the rear final drive in place.
3. Install the rear final drive mounting bolts, then screw new nuts onto them and tighten them to the required torque.
4. Check the alignment of the marks, then insert the bolts of the flexible coupling of the propeller shaft to the rear final drive flange, screw new nuts on them and tighten them to the required torque.
5. On models with ABS, connect the electrical connector to the rear wheel sensor.
6. Align the drive shafts with the rear final drive flanges. Lubricate the threads and heads of the new bolts with oil, then install the bolts and mounting plates on the drive shafts, screw in the bolts and tighten them to the required torque.
7. Install the wheels and screw in the wheel bolts, then lower the vehicle to the ground and tighten the wheel bolts to the correct torque.
