around 35 mph i get a death wobble from hell. im 99.9% sure its from the passenger front and its real bad when im braking. the last thing i remember doing to my truck was a brake job but everything was tight. any suggestions? im doing lower bjs/passenger hub during winter break. and im also sure its not the hub because when my drivers side went (unexpectedly at that) my wheel didnt shake, it just came off. any suggestions would be much appreciated.
