well guys Im back to this same issue again but this time I let out once the lights came on so nothing has broken yet. have even rebuilt the tranny recently, trans has 7000 miles on it so I dont see where the trans could be the issue. do you guys think it could be the rear end? Also I have redid my pinion angle 3 days ago hoping that would work but now vibrations are worse. Im extremely surprised with all the people on here with flip kits and lowered trucks that no one can advise me on how to measure my pinion angle, I know how to adjust it just not measure it to make sure Im in the -2 to -3 degrees that I need to be right now I THINK I'm around +3 which I know cant be good since its vibrating bad.
