Rear wheel hub (2WD)
1. Measure the hub axial clearance
a) (Models with drum brakes) Remove the cap and brake drum from the rear wheel hub.
b) (Models with disc brakes) Remove the brake caliper and brake disc.
c) Install the dial indicator as shown in the figure and measure the axial clearance of the hub by moving it back and forth.
The maximum permissible value is 0.05 mm
d) If the axial clearance of the rear wheel hub bearing exceeds the maximum permissible value, loosen and re-tighten the rear wheel hub nut and recheck the bearing breakaway torque.
Tightening torque: 175±25 Nm
d) If it is not possible to adjust the bearing starting torque, replace the bearing.
2. Measure the breaking moment.
a) (Models with drum brakes) Remove the cap and brake drum from the rear wheel hub.
b) (Models with disc brakes) Remove the brake caliper and brake disc.
c) Using a special tool, measure the bearing preload.

Maximum bearing breakaway torque: 22 Nm
d) If the bearing breakaway torque exceeds the maximum, loosen and re-tighten the rear wheel hub nut and recheck the bearing breakaway torque.
Tightening torque: 175 + 25 Nm
d) If it is not possible to adjust the bearing starting torque, replace the bearing.
Checking the overall clearance in the rear gearbox
If the vehicle vibrates or makes noise due to wheel drive imbalance, measure the overall clearance in the gearbox in the following order to determine whether the gearbox assembly needs to be removed.
1. Place the vehicle on a flat, horizontal surface.
2. Move the CVT or automatic transmission selector to neutral position ("N"). Tighten the parking brake lever (upper position) and jack up the car.
3. Turn the cardan shaft clockwise by hand until it stops. Mark the relative position on the dust boot (seal cover) of the main drive pinion flange and the gearbox housing.
4. Turn the cardan shaft counterclockwise until it stops. Measure the distance between the marks. If the gap exceeds the maximum permissible value, remove the gearbox housing and adjust the gaps in the gear engagement.
The maximum permissible value is 6 mm
5. Check for viscous coupling oil leakage.
Checking the oil level in the rear gearbox housing
Make sure that the oil level in the gearbox housing is below the edge of the filler plug hole (see figure). If necessary, add oil to the gearbox housing.
Oil class according to API — GL-5
Recommended oil viscosity (depending on temperature) according to SAE:
- Above 10°C - SAE90
- Below 10°C - SAE80VI
- Tightening torque of plugs - 49+9 Nm
Replacing the gearbox housing seal
1. Disconnect the drive shaft from the gearbox.
2. Remove the oil seal from the gearbox housing.
3. Using a special tool, press the new seal into the gearbox housing until it stops.
4. Apply general purpose grease to the seal lip and drive shaft contact surface.
5. Replace the drive shaft retaining ring with a new one, then install the shaft into the gearbox housing.
