A side-to-side caster difference can contribute to a vehicle drift in the direction of the side with less caster. If the difference cannot be corrected by Shop
Manual procedures (greater than 3/4~ difference), a service kit (for use on vehicles with forged axles) can be used to increase front wheel caster angle on
either or both wheels to balance the caster split. The kit contains complete parts and instructions needed to modify the front radius arm and mount a
metal cam on the bottom of the arm. The kit can increase caster from 1/2~ to 3 degrees, in 1/2~ increments. It is not designed to decrease caster.
Vehicles with stamped axles cannot utilize the caster kit, but can be serviced with a different procedure.
To increase front wheel caster angle of subject vehicles with forged front axles to balance the caster split, the following procedure is suggested:
1.
Remove radius arm from the vehicle as shown in Section 14-21 of the Shop Manual and choose appropriate paper template contained in the
service kit and identified by vehicle model.
