Alignment: Service and Repair

Caster and camber adjustments are made by means of shims located between upper control arm shaft and mounting bracket attached to suspension crossmember. A series of convex and concave spacers with flat opposite sides are used. These spacers allow a positive cross shaft-to-bracket attachment regardless of the number of shims used. Shims may be changed at either front or rear to vary caster, or at both points to vary camber.











CASTER
1. Measure frame angle at "B".
2. Check caster on alignment machine.
3. Using frame angle measurement and measured caster angle, determine actual (corrected) caster angle as follows:
a. Subtract a ``down in rear'' frame angle from a positive caster angle reading.
b. Add an ``up in rear'' frame angle to a positive caster angle reading.
c. Add a ``down in rear'' frame angle to a negative caster angle reading.
d. Subtract an ``up in rear'' frame angle from a negative caster angle reading.
4. Measure dimension ``A''.






5. Using dimension ``A,'' and Caster Specification Chart, find the recommended caster angle. Specifications
6. The frame corrected angle should correspond to the recommended angle on the chart within plus or minus 1/4°. Make necessary changes to bring caster angle within limits.



CAMBER
1. Determine camber angle using suitable equipment.
2. Add or subtract shims from both front and rear bolts to adjust camber as required.

TOE-IN
Toe-in can be increased or decreased by changing the length of the tie rods. A threaded sleeve is provided for this purpose. When tie rods are mounted ahead of the steering knuckle, decrease the length to increase toe-in. When tie rods are mounted behind the steering knuckle, increase the length to increase toe-in.
