    Paul what was your caster angle when you had it aligned?........as I understand shooting for +5*is what's best.....I think mine is 7* or 8 *

    One of these is the problem, if it's only steering. It the rig was beat, then broken frame, broken springs (if not new), broken spring mount.

    Yes, they do, they are located in the "C"s top and bottom, and this could cause all kinds of problems. The above was the only mention but you said the Jeep was beat and had 33, a very good combination for wearing them out, beside have you ever replaced (37yrs) or even greased them lately???

    I have to admit that i only did a quick scan of the thread,but I have had a similar problem in the Mitsu, out of balance tire, wheel hop around 45-55.
    Seperating tire tread, failed at 60 mph going down the highway.
    Only took 5 years to figure it out.

    This may be it, I will check it this weekend.....

    It's not really a shimmy problem as much as a darty problem.... wants to go its own way at times and over correcting in the steering...

    How old are your tires and what does the tread wear look like?

    If you lack sufficient knowledge, tools, etc. to take adavantage of the advice posted on this thread, I would suggest spending a few bucks and having a good alignment shop assess/correct your problems.

    My background... Auto shop teacher at a local H.S. have rebuilt many different engines, rear-ends, and general auto repair. I do not have alignment tools, but that is about it. I have owned this jeep since it was new. Brother had it for the last 10 years and beat the living sh*t out of it. So my sons and I have been doing a complete restoration/modification to it. Heck... we are around 300HP now... cool.... tires are OLD... 15 years... but look good.

    all tie roads and steering rods have also been changed.

    I was up under it looking at it again and I think I need to replace the part that is welded to the frame that hooks to the shackles. instead of being very parallel down it now tapers off.... thus not as tight as it could be..

    I've read this whole thread again. Caster is a huge factor in the symptoms you've been having problems with. Several of us have asked what your caster is now. Do you have a accurate number?
    When I put a 2" lift on my cj6 I could barely keep it between the painted lines....it was at about 2* positive. I added shims to bring it to 5* and it drove like a completely different Jeep. I now have a 4" lift running 7-8* caster w/ 33 tires and I can drive/steer it with my knee at 70mph....no problem
    So back to your caster.......think we should sort that out

    You keep saying that the steering box is loose, That needs to be tight or you will never get rid of the slop in the steering

    thx..

    I have tightened down the bolts to the max,,,, still loose thus I will have to have some special brackets welded to help secure the steering box (please keep in mind that it is power steering) also it is now leeking a little,,, can you have these things rebuilt? if so who and how much$$$...

    it seems that the frame flexes where the box is bolted on to.

    Have you checked the stock cast steel steering mount for cracks? Big tires and hard wheeling will crack the ears on these mounts. There are no after market mounts for the '72 to '75's but it's not hard to build one from 3/8's plate. Also you should be running a brace if you wheel it.
    The frames are know to crack at the box and yes you can get kits and rebuild the steering boxes.

    The shackle mounts that are welded to the frame are supposed to have a few degrees angle to them to reduce road wander. I wouldn't mess with them unless they are broken

    It is very possible that the bolt holes in the mounts are extremely worn or the mounting brackets are broken.
    If the box is leaking it will need rebuilding/replacing, and this can allow enough play in the shafts (especially if the bearings are worn ) to cause problems.
    If the frame is flexing at the mounting point it is likely there is a break in the frame beneath the mount. The flex wil move everything the steering is attached to causing the stability problems you pointed out.
