I just installed a used PAS pump from auto sports unlimited and holy cow I my truck rides great now. I thought I had some serious issues with my front end but it just was my pump was toast. This was my first time dealing with auto sports unlimited and for $70 for the pump (plus the pulley) how could you go wrong? They still have a couple more in stock so if you have a howling PAS pump that is near death I would pick one up.

 

Those guys rock over there.
Thats why I recommend them all the time.
Now if only I could get a little kick back from them...
