I had a 94 Ranger 4.0 4WD; they use an eccentric cam/bushing (solid, not rubber) for caster/camber adjustment that, as I recall (it was, after all, 1996 that I dealt with it), was inserted into the upper control arm. Seems to me it was about $40 installed and, of course, it was installed on the alignment rack because that's when they figure out which one you need, or if you even need a different one at all. One per side if it needs to be changed due to the stock one not allowing for proper alignment due to someone hammering the front end. They make different ones with the difference being the eccentric hole is in a slightly different spot relative to the center of the bushing. There is a limit as to just how much correction can be made, if you look at a pic of one you'll see that there needs to be some edge margin between the hole and edge of busing/cam. Not sure if you have 2 or 4WD, and if that makes a difference. If you look at the top of your upper control arm, ball joint area, you should see it (hex head) and it's self evident how it works.
They have them on rockauto, along with pics.
