The bolt has a flat side from end to end. The two identical cup shaped
washers have "D" shaped holes in them slightly off the center of the
washers. One faces each way so that when the bolt is turned, the washers
act like a camshaft. The outer edges of the washers go into a welded
fabrication attached to the frame of the coach. When assembled through the
bushing in the control arm, when the bolt is turned, the cam shaped washers
move the ends of the control arms in and out, or back and forth if you
prefer. The effect is to adjust camber and/or caster of the front
suspension through their range of eccentricity. This is not an "eyeball"
process. A small amount of motion results in precise alignment.
You need to have this right. Ballpark figures for the GMC fitted with
radial tires should be 3° positive Camber, and "0" degrees Caster. Tow
in/out adjustment should start @ 1/8" tow out, but under way the front
wheels tend to pull the wheels slightly tow in. All this is effective at
ride height being correct. If there is much slop in bushings, or ball
joints, or tie rod ends, etc. then close alignment is rendered moot. What I
got from here.
