MODEL 166, 292 

MODIFICATION NOTES

19.05.2015 Bolt, torsion bar bracket/torsion bar to front axle carrier Model 166 with code 468 (Active driving stability (roll stability)) BA32.20-P-1001-02Q
02.07.2015 Camber at vehicle level Model 166 AMG BE40.20-P-1001-13AB
G11974440
  Adjust     
1 Remove bolts (1) from rear transverse control arm mounting (2) or front transverse control arm mounting (3)    
2 Remove bolts of stabilizer bar bracket to front axle carrier and swivel stabilizer bar downwards If camber has to be corrected on front transverse control arm mounting (3).
IMPORTANT The caster angle at the front axle can only be changed by adjusting the camber.
IMPORTANT The torsion bar must be detached carefully, as it is under tension.		  
3 Mount old bolt (19c) or new bolt (19d) to front transverse control arm mounting (3) or rear transverse control arm mounting (2) IMPORTANT On integral carriers with lock tabs on both sides on the front transverse control arm mounting, only the new bolt (19d) may be used. The new bolt (19d) of the rear transverse control arm mounting (2) can be inserted from above or below.
IMPORTANT The old bolt (19c) can be replaced by the new bolt (19d).
The new bolt (19d) may only be used with washers (19e).		  
4 Screw nut (19b) of old bolt (19c) or new bolt (19d) on up to contact surface If camber or caster cannot be adjusted.
IMPORTANT Do not tighten nut (19b) of old bolt (19c) or new bolt (19d) to ensure that the elastomer bearing of the lower control arm can twist when deflecting.		  
5 Rock vehicle to settle suspension If camber or caster cannot be adjusted.  
6 Adjust camber IMPORTANT The adjustment (a) at the front of the lower transverse control arm towards the vehicle center causes a positive camber change.
IMPORTANT The adjustment (a) at the rear of the lower transverse control arm towards the vehicle center causes a reduction in caster.
IMPORTANT The adjustment (b) at the front of the lower transverse control arm towards the outside of the vehicle causes a negative camber change.
IMPORTANT The adjustment (b) at the rear of the lower transverse control arm towards outside of the vehicle causes an increase in caster.

8 Tighten nut (19b) of old bolt (19c) or new bolt (19d) NOTES
The old bolt (19c) or the new bolt (19d) must not be twisted after being fixed in place. When tightening the nut (19b) the old bolt (19c) or the new bolt (19d) must be counterheld.
Otherwise the lock tabs in the front axle carrier may be damaged.

10 Fasten torsion bar to front axle carrier If the camber on the front transverse control arm mounting (3) was corrected.
IMPORTANT The torsion bar must be mounted carefully, as it is under tension.
