Toe angle is measure per wheel. Measure toe angle at normal vehicle height, then measure again with a spring deflection of approximately 2.4 inches. If toe angle is not within specified limits, an eccentric tie link rubber bushing with a center offset is available for adjustment, Figs. 1 and 2. Prior to removing the tie link bushing, mark position of eccentric bolt to rear axle carrier. To replace bushing with tie link installed on vehicle, use tool No. 124-589-02-43-00. To increase toe-in, install bushing with arrow facing downward. To decrease toe-in install bushing with arrow facing upward.

Toe angle of the rear wheels results from the location of the rear axle carrier and the semi-trailing arms. Toe-in value depends within certain limits on the semi-trailing arm position of the rear axle.
Toe angle can be corrected by the installation of eccentric rubber mounts in the semi-trailing arms. Semi-trailing arm eccentric rubber mount part No. 1233520765 is available to correct toe-in. To reduce toe-in, install outer rubber mount (A) with arrow pointing toward the rear as shown, Fig. 3, and inner rubber mount (1) pointing toward the front.
To increase toe-in, install outer rubber mount (A) with arrow pointing toward the front as shown in Fig. 4 and inner rubber mount (1), pointing toward the rear.
