A side-to-side front wheel caster difference greater than 3/4 degree can contribute to a vehicle drift or pull in the direction of the side with less caster.
The service kit (E5TZ-3K064-A) can be used to increase the front wheel caster angle on either or both wheels to balance the caster split to correct a
vehicle drift/pull concern. The kit contains complete parts and instructions needed to modify the front radius arm and mount a metal cam on the bottom
flange of the radius arm. The kit can increase caster from 1/2 degree to 3 degrees, in 1/2 degree increments. It is not designed to decrease caster.
To increase front wheel caster angle of subject vehicles and/or to balance a caster split, the following procedure is suggested:
1.
Remove the radius arm from the vehicle as shown in Section 14-21 of the Reference Shop Manual and choose the appropriate paper template
applicable to the vehicle model.
