    Thumbs down 1993 Deville power steering pump failure

    My wife called me today when she got home for lunch, and said that the power steering in her car ('93 CDV) had stopped. She said that when she had gotten to the end of our street, she couldn't steer the car very well. That, and it was making some awful noises!
    I came home, popped the hood and saw the problem immediately! The first thing I saw was that the serpentine belt was half on the power steering pump pulley. The pulley was pushed out, and rubbing against the A/C condenser lines!
    I took the pump off, and the pulley and the shaft it's attached to popped right out! The inside of the pump has a bunch of metal shavings and some parts of it inside looked cracked. When I took the pump back to AutoZone, the guy tapped it on the counter and the clip that holds the shaft in came out in pieces. So I have no idea how, or why, but that clip snapped, and allowed the shaft to come out a bit.
    Oh yeah, I bought the last rebuilt PS pump on February 23rd! So it didn't even last a month before it crapped out! I asked the guy if this one would last at least a month, and he said I hope so!
    The water pump is making noises, so I'm going to change that first, along with the two radiator hoses and the T-stat before putting the "new" rebuilt power steering pump on! I have a new AC Delco water pump, so I shouldn't need to change that for a long time.

    I'm not crazy about autozone rebuilt parts, Ive had my share of troubles with them. I generally deal with Napa now and no more problems like that.

    Yeah, that's probably what I should have done is gone to NAPA the first time.

    Any other warning before it died? Mine squeals a bit and the last day or 2 the car has been pulling pretty hard to the right. Its either about to die on me, or my alignment went to crap.

    And our NAPA just closed down haha, only autozone and a few others now lol

    I don't know if you guys have them in the states, but up here I use Raymac parts, they are NASCAR certified for durability.

    No, I've never heard of them. I have a rebuilt PS pump from AutoZone on my '94 Deville, and that has worked flawlessly for over a year. So there just might have been some defect in this one.
    I did get the water pump changed...wow, what a pain!

    I was given the wrong pump by Advance went back and got the one with the correct shaft diameter. They loaned me the puller and installer. The adapter which was a dealer only part was the problem, I spent more on that than the pump. It was avery easy job, but you do have to bleed the pump when you are done.
