If during movement there is extraneous noise in the area of the rear wheel (usually it is a whistle or howl, which increases with increasing speed, strong heating of the hub), then the bearing is out of order and it needs to be replaced
By tightening the hub nut, it is impossible to eliminate the play of this bearing (if you tighten this nut there will be progressive wear, the axial play should not exceed 0.03 mm).
Figure 1 shows the rear wheel hub parts.
We replace the bearing in a pit or on a lift.
Release the rear wheels.
Remove the rear wheel.
Fully lower the parking brake lever.
Remove the rear wheel.
We knock it off with a chisel and remove the protective cap of the hub bearing.
Unscrew the hub nut.
Removing the brake drum
After removing the brake drum, do not press the brake pedal, as the pistons may completely come out of the wheel cylinder.
Bearing fastening in the hub (Fig. 5)
From the outside of the drum, using special pliers for removing retaining rings, remove the bearing retaining ring.
The bearing to be replaced is pressed out of the drum socket using a cup puller
You can knock out the bearing using a suitable mandrel, placing two wooden blocks.
Before installing a new bearing, clean the mounting surface for it in the brake drum.
Insert the bearing into the drum seat.
Press the new bearing with a puller until it stops, applying force through the mandrel to the outer ring of the bearing.
In this case, you can use the outer ring of the old bearing as a mandrel.
By supporting the puller cup on the other side of the drum, when pressing the bearing on a car with ABS, do not damage the setting ring of the rear wheel speed sensor.
Install the retaining ring in the groove of the drum.
Check the condition of the journal.
If its seating surface under the wheel bearing or the thread under the nut is damaged, replace the rear wheel hub axle.
To do this, use the E-16 head to unscrew the four screws securing the rear wheel hub to the flange of the rear suspension beam, remove it and install a new hub.
Mount the brake drum on the hub. The tightening torque of the bolts is 80 Nm.
Tighten the rear wheel hub bearing nut to a torque of 175 Nm.
