on the 2wd trucks, the idler arm bushings will cause the jiggle you describe. To confirm, Jack up the right front and move the wheel left to right, watching the idler arm located on the frame behind the wheel. If they are bad, you will see the outer part of the arm move on the shaft - there should be no movement if they are good. The bushings can be bought separately for about $10.00 or so on eBay or RockAuto.
