Lever Shaft
Before making adjustment, disconnect drag link from pitman arm. Loosen instrument panel bracket clamp on steering gear jacket tube. If cam bearing preload adjustment is required, it must be adjusted before proceeding as follows:
Unlock adjusting screw and turn it in until a slight drag is felt through the mid-position when turning steering wheel slowly from one extreme position to the other. Backlash of cam follower(s) in cam grooves may show up as end play of lever shaft or as backlash of pitman arm.
CAUTION:
Adjustment should be made only at mid-position and there must not be any binding at any point of travel.
Tighten lock nut and recheck adjustment.
