this may be an easy question for some of you guys, but i just need a little help with one thing. my truck (73 Jimmy 4WD) bounces like crazy, there may be a better word than bounce but that is all i can think of, but it is not like a bounce from bad shocks, it is pretty violent. i just got the tires (38" swamps) put on a few months ago and they were balanced. at the same time i had new springs and shocks put in. so if anybody could help me out with this that would be great. thanks!!!
