2	Check toe-out on turns	Model 171	BE40.20-P-1001-08A
		The steering geometry is checked by measuring the toe-out on turns. This is the difference in the steer angle between the outside wheel and the inside wheel when the inside wheel is steered through 20°. If substantial deviations are found, the cause may be one of the following, assuming that the camber and caster settings are correct: 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 cross member, wheelhouse and firewall, or on front axle carrier) which have a negative effect on the adjustment range for camber and caster can result in greater differences in the toe-out on turns between left and right.
