Removal
Attention! Removing the steering knuckle is a problem in the sense that you will subsequently need to go to a workshop to adjust the wheel alignment.
1. Loosen the wheel bolts and hub bolt with the vehicle standing on its wheels.
2. Jack up the car and place it on jack stands.
3. Bleed the air from the air spring, remove the corresponding front wheel and unscrew the hub bolt.
4. Release the ABS sensor plug from the holder on the steering knuckle.
5. Remove the brake caliper and secure it to the body so that its weight does not put any load on the brake hose, see the relevant chapter.
6. Unscrew bolt 5 of the ABS sensor mount (see illustration 3.6).
7. Remove the brake disc, unscrew the mounting bolts and remove the brake shield (see arrows in the illustration).
5.7. Unscrew the mounting bolts and remove the brake mechanism shield (see arrows)
8. Unscrew bolts 3 and 4, which secure the ball joint of the tie rod end to the steering knuckle (see illustration).
5.8. Unscrew bolts 3 and 4 securing the ball joint of the tie rod end to the steering knuckle
9. Disconnect the tie rod end from the steering arm 1 by pressing the rod down (see illustration).
5.9. Disconnect the end of the transverse steering rod from the steering arm 1 by pressing the rod down
Attention! It is not allowed to spread the spline on the steering knuckle with a chisel or other tool, or to push out the tip pin with a crowbar by inserting its blade between the steering knuckle and the sealing washer 2 (see illustration 5.9). In this case, the washer is damaged. If necessary, the pin can be knocked out with a wooden or rubber mallet.
10. Disconnect the ball joint of the guide arm from the steering knuckle, and then the bearing arm, see the corresponding chapter.
11. Unscrew the clamping bolt 1 and disconnect both upper arms 2 from the steering knuckle (see illustration 5.8).
12. Move the steering knuckle to the side, remove the outer CV joint tailpiece of the drive shaft from the hub and remove the steering knuckle. Secure the drive shaft to the body with wire so that it does not sag.
5.12. Disconnect the drive shaft from the gearbox by unscrewing the fasteners of its inner CV joint (see arrows)
Attention! When dismantling the steering knuckle, the vehicle manufacturer recommends removing the drive shaft by unscrewing the bolts securing its inner CV joint to the gearbox (see arrows in illustration 5.12).
Installation
The installation of the steering knuckle is performed in the reverse order of its removal.
13. Contact a specialized workshop and adjust the camber and toe-in of the front wheels.
