I bought a 94 4runner, runs great, bought to have a gaser around the city and just keep miles off my truck. Anywho, when i go over a speed bump or hit a bit crack in the road the back make a clunk noise like part of the back hit a part of the suspension or frame. The springs look ok, the shock look fairly ok, but i was under the impression springs are for going down and shock are to go up. So trying to track down what I need to replace to alleviate that noise. I saw it had torsion bars in the back, I had a Honda that had the same issue in the front and it had those and i replaced them and it fixed it, but IDK if these work the same. Any help would be greatly appreciated!
