    I have been having this weird clunk in my front end that a can't figure out. The only thing I have replaced were front rotors and the idler ARM. It just started and I can't figure it out. It only happens when I turn the wheels Sharp both ways. I know I need shocks but that more of a higher pitched sound, this is more deep and solid. Any ideas?

    We had a 90 3/4 and we had a clunk whenever we went over a bump. Turned out to be the ball joints. We checked them when we first heard the clunk but they looked fine. When we did finally take them off they had almost beaten themselves apart. The lower ball joints where fine. Just the upper ones were bad.

    jack the truck up and with the wheel full lock left and full lock right spin the tires. If you feel binding in a certain spot it will be that cv shaft (joint is going on it) or hold the wheel with it in the air at 12 and 6 and rock it in and out- if there is movement or clunk may be a ball joint or wheel bearing. cking at 3 and 9 it will probably be your steering (ie tie rod, pitman, idler arms)

    Jacking under the LCA doesn't relieve the t-bar. To do that you have to jack the frame so the LCA hangs free. To do the tests kmkalf is suggesting, jacking under the LCA would be the right place.

    by doing it the way i suggested you check the whole front end out and that is probably where your noise is coming from- whatever you do DO NOT take the bolt out for the torsion bars without the proper tool- there is a tremendous amount of force behind that

    im going to look at it today and see, kinda sounding like ball joints as it will do it all the time or only when it feels like it.
