An assistant is needed to complete the work, and you will also need:
- reliable support under the car;
- a stripper of internal lock rings;
- a set of tools for replacing the wheel bearing.
Removing
Warning! Press out the wheel bearing only if it is replaced, as it is likely to be destroyed during dismantling.
1. We prepare the car for work (see "Preparing the car for maintenance and repair").
2. Prying with a slotted screwdriver, remove the hub cap.
3. We place wheel chocks under the front wheels of the car.
Warning! Attempting to unscrew the hub axle nut without straightening its jammed end can damage the threads on the axle.
4. Tapping on the center punch with a hammer, we bend the edge of the nut jammed into the grooves of the drive shaft (in two places).
5. Have an assistant depress and hold the brake pedal.
6. socket wrench by 30 mm with a long collar, loosen the front wheel hub nut.
7. Remove the front wheel (see "Wheel - replacement") and loosen the hub nut.
8. Remove the brake caliper without disconnecting the brake hose from it (see "Front brake caliper - removal and installation").
9. Remove the brake disc (see "Brake disc - removal and installation").
10. We turn off two bolts of fastening of a spherical support to a rotary fist (see "Rack ball joint - removal and installation").
11. Turn off a few turns of the nuts securing the upper support of the rack to the body (see "Front suspension strut - removal and installation").
12. Having pressed the lower suspension arm down, we take the lower end of the rack to the side and remove the shank of the outer CV joint from the hub (see "Front wheel drive - removal and installation").
Warning! When performing the following operation, the force of the power bolt of the puller should be applied to the end surface of the hub, and not to the bearing ring.
13. We rest the paws of the puller on the steering knuckle and, turning the bolt nut, press the hub out of the steering knuckle.
14. Squeeze the puller and remove the retaining ring from the outside of the hub bearing.
15. On the reverse side of the steering knuckle, we compress with a puller and remove the other retaining ring of the hub bearing.
16. We install the fixture and press the bearing out of the steering knuckle.
17. If the inner ring of the bearing remains on the hub, press it with a puller from the kit, or with a universal two-jaw puller (there are special recesses on the hub for installing the puller paws).
Installation
1. Thoroughly clean the mounting hole for the bearing in the steering knuckle from dirt and corrosion.
2. With a puller, install the retaining ring on the outside of the bearing.
Warning! When performing the following operation (bearing pressing) the force of the power bolt of the puller must be applied only to the outer ring of the bearing.
3. We press the new bearing into the steering knuckle until it stops against the retaining ring.
4. With a puller, install the retaining ring on the inside of the bearing.
Warning! When pressing the hub, the power bolt must rest only on the inner ring of the bearing.
5. Using a tool, we press the hub into the inner ring of the bearing.
6. We insert the drive shaft into the splined hole of the hub.
7. We put a thrust washer on the shaft and wrap a new hub nut.
8. Install all removed parts in reverse order.
9. Install the wheel (see "Wheel - replacement") and lower the car. We fix the wheel with wheel chocks, and the assistant presses the brake pedal.
10. Tighten the hub bearing nut to a torque of 225.6-247.2 N·m (23-25.2 kgf·m).
11. We jam the edge of the nut into the grooves of the drive shaft (in two places) and install the hub cap.
