The car has a non-adjustable front wheel hub bearing. If there is play in the hub bearing, it must be replaced.
To perform repair work on replacing the front wheel hub bearing, you will need:
- reliable car stand;
- snap ring pliers;
- a set of tools for pressing out and pressing in the front wheel hub and its bearing.
Removal
Warning: Only press out the front hub bearing if you are replacing it, as it will likely be damaged during removal.
1. Prepare the car for work (see "Preparing a car for maintenance and repair").
2. Remove the decorative wheel cap (see "Tires - Checking Pressure").
3. Using a slotted screwdriver, remove the front wheel hub cap.
4. Place wheel chocks under the front wheels of the car
5. Tapping the center punch with a hammer, bend back the edge of the nut that is jammed into the groove of the drive shaft (in two places) (see p. 4 "Rear Wheel Hub Bearing - Replacement").
6. Using a 30 mm socket wrench with a long handle, loosen the front wheel hub nut.
7. Remove the front wheel (see "Wheel - replacement") and unscrew 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. Unscrew the two bolts securing the ball joint to the steering knuckle (see "Ball joint of the rack - removal, installation, replacement").
11. Loosen the nuts securing the upper support of the strut to the body by several turns (see "Front suspension strut (without steering knuckle) - removal and installation").
12. Pressing the lower suspension arm down, move the lower end of the strut to the side and remove the splined end of the outer CV joint from the hub.
13. Resting the paws of the puller on the steering knuckle, turn the bolt nut and press the front wheel hub out of the steering knuckle.
Caution: The force of the power bolt must be applied to the end face of the hub, not to the bearing race.
14. Using pliers, remove the outer retaining ring of the hub bearing.
15. From the back of the steering knuckle, use pliers to remove the inner retaining ring of the hub bearing.
16. Install the device and press out the bearing from the front hub.

17. If the inner bearing ring remains on the front hub, press it off using the puller from the kit or a universal two-jaw puller (there are special recesses on the hub for installing the puller's paws).
Installation
1. Carefully clean the bearing bore 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. Press the new hub bearing into the steering knuckle until it stops against the outer retaining ring.
4. Install the inner retaining ring of the hub bearing.
Warning: When pressing the hub, the power bolt must rest only on the inner bearing race.
5. Using the tool, press the hub into the inner bearing ring.
6. Insert the drive shaft into the splined hole of the hub.
7. Place the thrust washer on the shaft and tighten the new hub nut.
8. Install the front hub bearing and all removed parts onto the vehicle in the reverse order.
9. Install the wheel (see "Wheel - replacement") and lower the car. 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. Press the edge of the nut into the grooves of the drive shaft (in two places) and install the hub cap.
