95 F250. Had an occasional violent shake in the front of the truck. Went through the front end, ball joints, tie rod ends ect. All good and tight, took it to the shop and they couldn't find a reason for it. Yesterday I replaced the radial arm bushings, drivers side was shot. Thought I had it fixed. Now it shakes violently above 45-50mph. Sooner if you hit a bump in the road. It will stop if you slow down to 20mph and accelerate again. As soon as you get up to speed it starts shaking again. I'm at a loss, no one can find the problem. HELP PLEASE
