I've got a '66 122 that I just replaced the front suspension bushings and ball joints on and now at speeds around 35mph I get VIOLENT shaking of the car (almost as if the tires are barely attached to the car). I went through and made sure all the nuts and bolts that were involved in the process were up to spec and the lower control arm long bolt on both sides of the car was a little loose. So I tightened it to 110 ft-lbs per the vclassics bushing replacement tech article and took it for a test spin in the neighborhood. All seemed fine up to ~40mph and then I hit a small bump in the road and the shaking commenced (not as violently as before, but still bad). My tires are badly worn, biased towards the inside, and my guess is the tires got bad because there wasn't really much left of the old bushings I was replacing.

So my question is did I mess something up in my replacement that's causing the wobble, or now that the bushings and ball joints are new, the tires' wobble is more pronounced (not that there was any noticeable wobble before the procedure)?

Logically, I think it's something I did because it seemed fine before I tampered with it, but is it possible the next weakest link is making itself known?

Thanks for the help.
