ok so i did some searching and none of the post i found had any solutions posted. well for a while now i have had a bad vibration/shudder on take off. well i thought it was coming from bad axle wrap. well i got traction bars installed finally after breaking a set of springs. well the vibration is still there and if anything it has gotten worse. u-joints all seem to be good. i have not checked carrier bearing yet. i kinda think it is coming from the lsd but at the same time i don't think so cause it will do it taking off in a straight line. what are some things i can check please. i can't afford to throw parts at so i want to do what i can to try and pin point the cause.
