Lower A Arms
 

Put new bushings in my 72 1/2 ton C10, When install the lower a frame I notice A lot of side to side moving. What is the proper way to reinstall Them ? !/2" u bolts holding them in place. Is this part of the alinement process adjustment ??

there is a locator pin , in the lower saddles, that must fit into locator holes that are in the control arm shafts, tighten the u bolts evenly, until they are fully torqued, there should be no play, between the saddles, and the shafts, once tightened. front end alignment caster and camber is set by adding or subtracting shims on the upper control arm studs, and tow adjustments are made by turning the tie rod adjuster sleeves, on the steering linkage

It is possible that your index pin/rivet could be sheared off. I had that problem on my Burban when I rebuilt my front end. See the link below and scroll to post 244 to see what I found on mine.
