Hello everyone. Upon pulling a heavy car hauler trailer the other day I was looking at the gap between my bump stops and my axle and noticed my whole diff seemed to be pointed skyward putting the pinion angle at a very bad angle I've also been fighting with a vibration at around 60 MPH and a slight hopping feeling the picture I will attach. It definitely does not look right. Any thoughts on why it's this way or what happened? It has blocks but they are flush so I don't see how it could have tilted the axle without having a gap somewhere??? Any ideas ?
