Checking toe constant after adjusting
The alignment unit checks the toe constant again.
If the second check shows that the values are within the check value tolerance, the setting is OK.
If the measured values are outside the control value tolerance, the setting must be adjusted again in lifted position.
Note: For wheel bearing housing without a groove and a tie rod end with a ring, the upward adjustment travel is about 2 mm less. If the adjustment
travel is not sufficient, then the ring on the tie rod end should be removed.
