4.1 To adjust the camber and caster, replace each standard bolt connection (A) to the torque strut (18) or spring control arm (17) with a repair bolted connection (B).

19b Repair kit nut
19c Repair bolt
19d Shims
19e Shims
19f Nut, standard bolt
A Standard threaded connection
B Repair threaded connection
The standard bolt (19a) is centered by lock tabs in the front axle carrier. Inserting the graduated disks (19d) onto the lock tabs, enables the repair bolt (19c) to be installed through the groove on the right or left.
The repair bolt (19c) may not be turned after fixing. Otherwise the lock tabs in the front axle carrier may be damaged.
Do not yet tighten nut (19b) to enable the rubber mount on the torque strut (18) or of the spring control arm (17) to rotate when the vehicle is rocked to settle the suspension.

19g Adjusting disk (eccentric bore)
A Standard threaded connection
C Repair threaded connection
For adjustment operations, the shims with centric bore (19e) must be replaced with adjusting disks with eccentric bore (19g).
The standard bolt (19a) may not be turned after adjustment. Otherwise the adjustment tabs on the front axle carrier may be damaged. Screw on the nut (19f) until it abuts, but do not tighten yet so that the rubber mount of the torque strut (18) or spring control arm (17) can twist when rocking the vehicle to settle the suspension.
