Steering Angle

When a vehicle negotiates a turn, the inner wheel must turn at a sharper angle than the outer wheel, and the outer wheel must travel farther than the inner wheel. Vehicle steering geometry is calculated to allow for these variations, causing the outer wheel to toe-out by a calibrated amount. This toe-out on turns is also referred to as steering angle and on these models, is generally checked at two positions. The first position is at a reference point on the inner wheel travel while the second position of measurement is at full steering lock. To check steering angles, proceed as follows:

Fig. 8 Turning Angle Specifications:

1. Turn steering to full lock and measure inner and outer wheel turning angles.
2. If ``Turning Angles'' at full lock are not within specifications, Fig. 8, check for damaged steering linkage or improperly adjusted tie rods.
3. If steering linkage and tie rods are satisfactory, check for improper rack or rack piston stroke and repair steering gear as needed.
