Damage code Cause Remedy  
40 214 B4 IMPORTANT The vehicle follows the inclination of the road due to the laws of physics! 1 Test drive vehicle (team chief/customer) and verify complaint.  
 
  • Low friction (counterforce) in the axle joints as well as in the area of the steering/jacket tube (provides good feeling of contact with the road and leads to good return).
 IMPORTANT To ensure neutral evaluation, it is necessary to make a visual check to ensure that the tire inflation pressure and vehicle level are OK (vehicles with pneumatic suspension/ABC not inclined to one side).  
 
  • Wide tires increase the tendency to runaway and the sensitivity to ruts. If this is the only reason for complaint, there is no remedy.
 2 Determine influence of tires
IMPORTANT Change wheels crossways left/right on front and rear axles (including unidirectional tires).
IMPORTANT If this does not remedy the problem, continue with step 4.
IMPORTANT If the vehicle is OK after changing the wheels crossways, non-unidirectional tires can remain on the vehicle.		 AP40.10-P-4050Z
    IMPORTANT For unidirectional tires:
↓
3 Optimize bead seat.		  
40 221 B4
40 211 B4		   Press tires off of rim and inflate according to AF AF40.10-P-3201-01AV 
    4 Check axle adjustment.  
    IMPORTANT If the vehicle is not okay with the axle adjustment symmetrically (actual value) in spite of changing tires in crisscross pattern:
↓
5 Change caster as follows:		  
    Model 203 AR40.20-P-0200P
    Model 211 AR40.20-P-0200T
    Model 230 AR40.20-P-0200R
    IMPORTANT Left: Increase caster, increase camber (in negative direction)
Right: Reduce caster, reduce camber (in positive direction)
IMPORTANT For this purpose, use caster and camber correction bolts.		  
    Model 203 AR40.20-P-0322-01P
    Model 211 AR40.20-P-0322-01T
    Model 230 AR40.20-P-0322-01R
    6 Test drive vehicle (initial evaluation).
