when i was building my backhalf and 4 link, i got my backhalf completely finished and then i started on my 4 link system. i built my lower bars first and then installed them. then i built my upper bars and mounted them to the same crossmember as my lowers, but i wasnt paying attention and didnt really take measurments of the lowers compared to the uppers. anyways, i guess the angle of the uppers ended up making the top bars about 1.5" longer than my lowers. i just realized this when i took it all apart to repaint everything. when i drive between 42-47 MPH i feel a vibration and i belive it is because of the length of the uppers, but my pinion dont change. do you guys think that such a small difference would cause a vibration?
