11 Bolts M6x12 for fastening the shield 12, 12 Nm
12 Brake guard
13 Steering knuckle
14 Bolts M12x1.5x45, to be replaced, 70 Nm, then tighten by 90°

Loosening and tightening the hub bolt
Caution: After removing the wheel bolt, do not load the wheel bearing (do not lower the car to the ground), otherwise the bearing will be damaged. When the vehicle is on the ground, do not loosen the wheel bolts by more than 90°. If it is necessary to roll the vehicle without a drive shaft, fit the outer CV joint and tighten the old hub bolt to 120 Nm.
2. Provide access to the hub bolt. To do this, depending on the installed wheels, remove the decorative cap of the steel wheel disk, or the central protective cover of the light alloy wheel disk (see "Section Jacking/Hanging and Emergency Vehicle Transportation" in the introduction). Wheels with regular alloy wheels should be removed, push out the protective plug of the hub bolt from the inside and install the wheels back.
3. Loosen the hub bolt (see resist. illustration) no more than 90°.
2.3 Hub bolt
4. Raise the car just enough to relieve the front suspension (wheels must not touch the ground).
5. Ask an assistant to depress the brake pedal so that the wheel does not spin, and remove the hub bolt.
6. With the clutch pedal depressed, tighten the new hub bolt to 70 Nm.
7. Lower the vehicle to the ground, tighten the hub bolt 90°and close it with a protective plug or cap/cap.
Removal and installation of the hub assembly
8. Remove the hub bolt (see subsection above).
9. Remove the front wheel.
10. Remove the caliper with anchor bracket and hang them on the body parts on the wire without disconnecting the brake fluid hose (see chapter 9). In this case, the hose should not be tense.
11. Remove ABS wheel sensor and brake disc (see chapter 9).
12. Push the wire shaft out of the hub as far as possible towards the transmission.
13. Turn out bolts (see resist. illustration) and remove the hub assembly from the steering knuckle.
2.13 Hub assembly mounting bolts
14. Installation is carried out in the reverse order. Tighten the bolts of the front hub assemblies with a force of 190 Nm.
