Withdrawal
1. Mark the direction of rotation of the wheel on the tire. Loosen the wheel bolts. Raise and place the car on stands and remove the wheels.
Caution: Be sure to follow the instructions in Section In case of emergency.
2. Secure the brake disc with one wheel bolt.
Warning: For vehicles with headlight range adjustment, before removing the left suspension strut, loosen the vehicle level sensor connecting rod by opening the carrier arm retaining clip.
3. Disconnect the ABS electrical wire from the holder on the caliper.
4. Remove the caliper and fix it on the suspension so that the weight of the caliper does not affect the brake hose and brake pipeline, refer to Section Removal and installation of a brake disk/caliper.
5. Remove the clamp with pliers (1). The clamp should no longer be installed.
6. Loosen the nut (2), remove the bolt and lift both suspension arms up.

7. Protect the tie rod housing with a shell (1) from damage. HUNDRED AUDI apply for this protective shell No. 893 512 137.
8. It is necessary to cut a strip of size A = 20 - 25 mm from the protective shell. Bevel sharp surfaces carefully. The cutout of the shell during installation must look down.
9. Place a garage jack under the swing arm with a piece of wood so that the suspension does not drop too low when the shock strut is released. Otherwise, lower control arm joints may be damaged
10. Remove the bolt (arrow on accompanying illustration) and fold the wheel bearing housing aside.
