Help....end play in PS pump shaft??

[seafish]

While checking all of the pullies and idlers on my 2005 with the serp belt removed, I found that I can move the pulley on the power steering pump in and out (end play) over 1/8".



I have NEVER experienced this on a PS pump before, so it does NOT seem normal to me, although there are no other signs of a problem, no side play, no noise, etc.



Is this end play in the PS pump shaft NORMAL or is it a sign that the bearings going out??



TIA!!!

I have found end play on every 3rd gen I've checked, some with over 600,000 miles on what I assume is the original pump. Drive on...

Godspeed,

Mine developed a leak around the shaft. I took off the belt and found about the same amount of end play you did. At the time I thought it was leaking because of the end play but I can't really say if the end play and the leak were related or not. Maybe not.



I did replace the pump with the latest style which caused a lot of new problems with belt jumping etc. Don't get me started on that saga. #@$%!

Actually, if you don't mind, please DO get started on that saga, as I AM thinking of upgrading to the NEW PS pump along with the NEW steering box which IS going in under warranty.

Many thanks for your input!!

Mine is post #4 in this thread. Explains it pretty well.

I had the dealer do it because of an article in the TDR about the new pump. It said that with a new bracket the pulley alignment might be off and the adjustment was critical.



Stupid me thought the dealer would do it right. If I had it to do again, I would do it myself.

So there is nothing inherently wrong with the new pump and resorvoir set-up, and it IS an upgrade, but it is important to have the pulley aligned carefully on the PS pump shaft.

OK Thanks... now I remember that thread.
