	Adjust
1	Loosen bolted connections (1) on transverse control arm mountings (2, 3)
2	Remove bolts of stabilizer bar bracket to front axle carrier and swivel stabilizer bar downwards	Only if camber has to be corrected at front transverse control arm mounting (3). The caster angle at the front axle can only be changed by adjusting the camber. Remove stabilizer bar carefully as it is pre-loaded
3	Install repair bolt (19c, 19d) onto front (3) or rear (2) transverse control arm mounting	Only if the camber or caster cannot be adjusted. Screw on the nut (19b) of the repair bolt (19c, 19d) until it abuts, but do not tighten yet so that the elastomer bearing of the lower transverse control arm can twist when the vehicle is rocked to settle the suspension. On interior carriers with lock tabs on both sides of the front transverse control arm mounting, only the new repair bolt (19d) may be used. The new repair bolt (19) for the rear transverse control arm mounting (2) can be inserted from above or from below. The old repair bolt (19c) can be replaced with the new repair bolt (19d). Only use the new repair bolt (19d) with washers (19e).

6	Tighten the nut (19b) of the repair bolt (19c, 19d)	The repair bolt (19c, 19d) must not turn after fixing. Counterhold the repair bolt (19b) when tightening the nut (19c, 19d). Otherwise the lock tabs in the front axle carrier may be damaged.
7	Tighten bolted connections (1) of transverse control arm mountings (2, 3)	Bolt of lower transverse control arm at front to front axle carrier	*BA33.20-P-1004-01R

		Bolt, lower transverse control arm at outside rear to front axle carrier	*BA33.20-P-1007-01R
8	Fasten torsion bar to front axle carrier	Only when camber on front transverse control arm mounting (3) had to be corrected. Mount stabilizer bar carefully as it is pre-loaded
8	Fasten torsion bar to front axle carrier	Bolt, stabilizer bar bracket/stabilizer bar to front axle carrier	*BA32.20-P-1001-02Q
