Using an 18 mm wrench and an 18 mm head, unscrew the nuts 4 securing the shock absorber struts 5 to the steering knuckles.

Remove the bolts 7 and disconnect the shock absorber struts from the steering knuckles.

Remove the front wheel drives.

Using a 16 mm head, unscrew the nuts 2 (Fig. 15) securing the ball joint pins outer ends 3 steering rods and press out the pins from the levers of the steering knuckles 6.

Using a 18 key, a 18 head, unscrew the nuts 4 of the bolts securing the shock absorber struts 5 to the steering knuckles.

Remove the bolts 7 and disconnect the shock absorber struts from the steering knuckles.

Remove the front wheel drives.

Using a 13 mm head, unscrew and remove bolts 1 (Fig. 16), the upper fastening of the struts 2 of the front suspension subframe to the body.

Using a 13 mm head, unscrew the bolts securing the heat shield of the steering gear and remove the heat shield

Using an 18 mm head, unscrew the two bolts securing the steering gear to the front suspension subframe.
