2. Raise the car. Unscrew all five wheel bolts and remove the wheel.
3. Unscrew the hub center nut fully, remove the wheel sensor (1).
4. Use a pair of slip-joint pliers to press in the brake piston (2). Remove the brake caliper (3) from the swivel member and suspend it from the wheel housing by means of a cable tie.
5. Remove the brake disc and back plate (4).
6. Slacken the nut on the track rod end. Press out the track rod end bolt, using puller 89 96 696 (5). Remove the nut and lift the track rod end bolt out of the hole.

12. Remove the mounting and the top spring cup.
13. Remove the springs, rubber gaiter and stop.
14. Unscrew the MacPherson strut insert (11), using special tool 89 96 670.
15. Lift the MacPherson strut insert out of the MacPherson strut.





16. Place two pieces of flat or square bar under the MacPherson strut (1).
17. Press the front wheel hub off the wheel bearing (2). Use special tool 89 96 704.
18. Remove the circlips from the MacPherson strut.
19. Remove the wheel bearing from the steering swivel member (3). Use special tool No. 89 96 704, or equivalent.





INSTALLATION
1. Install the outer circlip on the steering swivel member. The opening in the circlip should face downwards.
2. Press the wheel bearing in until it abuts against the circlip (4). Use special tool 89 96 704. Lubricate the bearing seat and the periphery of the bearing with grease such as Molykote G Rapid Plus.
3. Install the inner circlip on the steering swivel member. The opening in the circlip should face downwards.
4. Install the hub in the wheel bearing (5). Use special tool 89 96 704.
5. Install the MacPherson strut.





6. Inspect the rubber gaiter and bushes, making sure that they are intact and undamaged.
7. Screw the MacPherson strut insert in place, using special tool 89 96 670 and torque to 215 Nm (158.7 ft. lbs.).
8. Install the spring. The lower end of the spring should rest against the stop in the bottom spring cup.
9. Install the spring shim (with the protruding mark as shown in the illustration above) and the mounting. Make sure that the lower washer is fitted the right way round (with the part No. facing downwards). Grip the piston rod with a suitable tool and tighten the nut, using special tool 89 96 662. Remove the spring compression tool (part Nos. 88 18 791 and 88 18 809).





10. Install the MacPherson strut in position on the car and tighten the three nuts at the top mounting (1). Tighten the nuts alternately to 18 Nm (13.3 ft. lbs.).
11. Tighten the nut securing the ball joint (2) to 75 Nm (55.4 ft. lbs.).
12. Tighten the nut securing the anti-roll bar to the link arm (3) to 10 Nm (7.4 ft. lbs.).
13. Install the back-plate and brake disc (4).
14. Check that the brake piston is pressed back into the cylinder.
15. Install the brake caliper to the swivel member (5). 10 Install the wheel sensor (6).
16. Tighten the hub centre-nut slightly (7).

CAUTION: If the hub centre-nut has been slackened or removed, a new centre nut must always be fitted. This is because the locking device on the nut will be less effective if the nut is refitted.

17. Install the wheel and tighten the five wheel bolts to 105 - 130 Nm (77.5 - 95.9 ft. lbs.).
18. Lower the car and tighten the hub centre nut when all four wheels of the car are on the floor (7) . Tightening torque: 290 Nm (214 ft. lbs.).
19. Tighten the nut at the top mounting (8), using a torque wrench to 90 Nm (66.4 ft. lbs.).
20. Pump the brake pedal to advance the brake pistons in the calipers.
