The nuts on the left of your pic are the bushings. The only rubber in the front end of a 3/4 ton are the sway bar bushings. on the 3/4 ton, the shaft actually turns in the threads as the suspension works. they can be tricky to put together because the bushings thread onto the shaft AND into the control arm. and when you get done the shaft should turn freely. I don't know how to tell you how to do it. I can't remember exactly now, but it took some playing with it to get it right.
