Check toe-out angle - AR40.20-P-0325NKB

MODEL 117, 156, 176, 242, 246 

INSPECT Check     
1 Check toe at front axle and adjust if necessary   AR40.20-P-0200NKB 
2 Check toe-out angle IMPORTANT The steering geometry is checked by measuring the toe-out angle. This is the difference in the steer angle between the outside wheel and the inside wheel when the inside wheel is steered through 20°.
IMPORTANT If substantial deviations are found, the cause may be one of the following, assuming that the caster is correct and the camber is set correctly:
  • Toe not adjusted with the rack-and-pinion steering in the straight-ahead position, resulting in tie rods of unequal length.
  • Steering knuckle or tie rod bent.
  • On vehicles involved in an accident:

Excessive deviations in the front end (longitudinal frame member, frame crossmember, wheel well and firewall, or at the front axle carrier) which have a negative effect on the adjustment ranges for camber and caster can result in greater differences in the toe-out angle between left and right.
