I bought my 94 shorty in July last year, I looked it over for the usual rust rot that I am aware of on these trucks, didn't see anything bad, just surface rust around the edges I wasn't worried about. Lately my steering has been feeling a little funny, kind vague and things felt like they were shifting in turns... I did some investigation while changing my oil and happened upon a decent sized hole in my frame between the steering box mounting bolts. Then I noticed some cracks on the outside of the frame near the rear steering box mount. I had someone turn the steering while I watched the box, it moved a little, then when it reached the stops the frame would get all twisted out of shape. I'm sure while yanking the truck through turns it probably is moving all over. So I started taking off the box and things.. got stuck when the strut bar bracket bolts that go up into the frame just spun. The captive nuts inside the frame had rusted off the frame and were spinning.... I got the box of and had a closer look. You can see with it off how far the crack goes underneath that rear mount. So I cut out most of the bad stuff on the outside, then I was able to use vice grips to hold the nuts in the frame so I could remove the strut bar bracket. Look what I found!
