I am trying to solve a problem and wantd to see if anyone had encountered this before. I have broken two power steering pump belts in as many days. The belts are good qulity units (Goodyear) and they are being torn in two. The pump I purchased from a bone yard about 8 months ago and have not had any problems until now. Someone suggested the pump may be locking up, but I am not sure how to go about verifying this. The pulley has a slight wobble in it but nothing too bad. Any ides or suggestions on where to start trouble shooting, The only thing I have come up with is replacing the pump and see if it happens again, I hate the wait and see thing though since it will always happen at a bad time.
