so im driving along and all of a sudden i lose power steering, no big deal maybe the belt went. so i pop the hood and the belt is still hanging there intact but off the pulley, weird, so i go to put it back on and notice the pulley itself is wobbling. the shaft itselft doesnt wobble so my question is can the pulley be tightened back on? i tried but the shaft just spins with the pump. by the way the pump is not factory i dont know if that makes a difference
