Not just solid front axles. The 70's era GM/Chev vans were infamous for the death wobble. I worked for a company that 20 or 30 of them & most developed it. The one I drove got so out of the blue, when driving at highway speed, that wobble would start & was so violent that there was no way to hold the steering wheel still & the whole vehicle felt like it was just going to blow up. Pretty damned scary the first time, and the 2nd, 3rd, 4th...
Replacing ball joints, shocks, etc didn't clear it up, so a steering damper was installed & that did the trick.
