ahh clink clank stupid control arm bolts.

I was wondering why in reverse if I hit a bump it would clank. I can move the rear upper control arm bolts by hand. These have never been touched so kinda odd but with all the work I did with JKS front/rear trackbars and quick discos should only take an hour max. Anything I am missing since I have seen conflicting info on the actual bolt sizes. m10x1.5x 80 to m10x1.75x???

The bolt size is M10x1.50x78.20. <--- This is from the FSM.

If they are flopping around, its sounds like the bushings may be shot.

yeah they are shot I dont want to tighten it and bend the actual control arm metal.

Question:

Why do I still have severe bump/torque steer? I raised the T-case, aligned the axle don't have any vibes that I can notice. If at say 65mph I let off gass it pulls right and accelerating it pulls left. could it be the shot bushings in rear control arms?

I appreciate any response as this is my DD and need to drive on highway every day. As it is now I don't think it is safe!

bad control arm bushings are going introduce axle wrap and throw off thrust angle. the axle isn't going to want to stay perpendicular to the frame.

bump steer and torque steer are two different things. don't confuse them.

you can't bend the "control arm metal" by tightening the bolts. the Clevite bushings have a sleeve inside them. the bolt squeezes on the sleeve, making it immobile, the bushing acts as the pivot & cushion.



To replace the bushings, some people burn them out. Then collapse the housing, pull it out and press in the new one with a BFH.

I didn't want to make a huge mess, so I made a bushing press: http://www.jeepforum.com/forum/f9/un...ml#post9547610
