To perform repair work on replacing the front wheel hub bearing, you will need:
- reliable support under the car;
- pliers for removing retaining rings;
- a set of tools for pressing and pressing the front wheel hub and its bearing.
Removing
Warning. Press out the front hub 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. Remove the decorative wheel cap (see "Tires - pressure check").
3. Using a slotted screwdriver, remove the front wheel hub cap.
4. We put wheel chocks under the front wheels of the car
5. 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) (see point 4 "Rear wheel hub bearing - replacement").
6. Using a 30 mm socket wrench 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, installation, replacement")
9. Remove the brake disc (see "Brake disc - removal, installation, replacement").
10. We turn off two bolts of fastening of a spherical support to a rotary fist (see "Rack ball joint - removal, installation, replacement").
11. Turn off a few turns of the nuts securing the upper support of the rack to the body (see "front suspension strut (without steering knuckle) - 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 splined tip of the outer CV joint from the hub.
13. Having rested the paws of the puller on the steering knuckle, turning the bolt nut, we press the front wheel hub out of the steering knuckle.
Warning. The force of the power bolt should be applied to the end surface of the hub, and not to the bearing ring.
14. Use pliers to remove the outer retaining ring of the hub bearing.
15. On the reverse side of the steering knuckle, use pliers to remove the inner retaining ring of the hub bearing.
16. We install the fixture and press the bearing out of the front hub.
17. If the inner ring of the bearing remains on the front 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. Install the outer retaining ring of the hub bearing.
Warning. The force of the power bolt when pressing in the front hub bearing should be applied only to its outer ring.
3. We press in a new hub bearing into the steering knuckle until it stops against the outer snap ring.
4. Install the inner circlip of the hub 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. We install the front hub bearing and all removed parts on the car in reverse order.
9. Install the wheel (see "Wheel - replacement") and lower the car. We fix the wheel with wheel chocks.
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.
