Re: CJ-7 steering problems, please help!?
you need to find an expert on 4wd alignment, or if you can't find someone knowledgable get books and start reading. there is something bent or broken on your jeep, the question is how much are you willing to spend till someone finds the problem.
If it was my jeep I would get a service manual and start by disassembling the hubs, brakes, spindle, and axleshaft. If you are going to own a jeep you will need to learn how to replace steering U-joints, and this would be a good time to check them over. while it is apart you can get a real good look at the spindles, they may be bent, or the mount bolts might be loose or stripped. the ball joints can be inspected. Last of all you can get a better look at the axle housing to see if it is bent.
there is plenty of knowledge on this BB, just do a search on the subject, if that dosn't help, just ask.
