FRAME & UNDERBODY

Note. (Scheme 9) is not intended to represent the exact structure of each vehicle's frame, underbody or body outline. It is presented only to provide reference points.

The following illustration indicate areas (parts) of the underbody and frame which may be used to raise and support the vehicle, using either floor jack or hoist. These points are indicated by shaded areas on the frame. (Scheme 9)

Scheme 9

OUTERBODY

Those points designated on the outline of the body were specifically designed to facilitate the use of the vehicle's own jack. These jacking points are indicated by circular dots on the outline of the body. (Scheme 9) If using floor jack or hoist, exercise extreme care to avoid damaging outer body shell.

Front

Note. A camber change always involves a toe-in change. Therefore, camber must be adjusted first.

Scheme 12

1. Remove centering pin (1). This pin is no longer needed. Remove dirt in area of support bearing in wheel arch from below with compressed air. Slacken nuts (2) approximately 1 1/2 turns. Remove nut (3). (Scheme 10)
2. Insert special tool (32 3 144/145) into opening of wheel arch and over stay bolt/nut (3). Adjust camber by turning nut. See «WHEEL ALIGNMENT SPECIFICATIONS»(ref-162531-S01235456042004060400000). Replace nuts (2) and tighten. (Scheme 11) See «TORQUE SPECIFICATIONS»(ref-162531-S13955596472004060400000).
3. Remove special tool. Replace nut (3) and tighten down. (Scheme 12) Tighten to specification. See «TORQUE SPECIFICATIONS»(ref-162531-S13955596472004060400000).
4. Adjust toe-in. See «TOE-IN ADJUSTMENT»(ref-162531-S32652017712004060400000).

2. Loosen hexagon collar nut (1) by 1/2 turn. CAUTION: If the nut (1) is tightened down more than 10 times during adjustment, it must be replaced again. The self-locking effect becomes too slight.
3. Adjust camber with eccentric screw. Adjust to specification. See «WHEEL ALIGNMENT SPECIFICATIONS»(ref-162531-S01235456042004060400000).
4. Ensure eccentric washer is correctly located between the stops (1). (Scheme 14) Tighten hexagon collar nut to specification. See «TORQUE SPECIFICATIONS»(ref-162531-S13955596472004060400000).
