Check Front Toe Angle Differential
1. Check and adjust toe-in at front axle2. Checking toe-out on turns
- Toe-out on turns is measured to check the steering geometry. This is the difference in wheel steer angle between the wheel on the outside of the curve and the wheel on the inside of the curve when the wheel on the inside of the curve is steered through 20°
- Greater deviations may be due to the following causes, assuming that the camber and caster are correctly adjusted.
a. Toe-in not adjusted in the straight ahead position of the steering gear so that the track rod lengths are uneven
b. Steering knuckle arm, pitman arm, or steering idler arm distorted
c. Excessive deviations at the front end on vehicles involved in accidents (frame longitudinal member, frame cross member, wheelhouse and firewall or on the front axle carrier) which have an adverse effect on the range of adjustment for amber and caster so that large differences in toe-out on turns result between the left and right
- Toe-out on turns with inner wheel at 20°:
- Range: -0.25 to -1.25°
- Preferred: -0.75°
