Hi All, Often my s70 has stiff power steering. I have noticed there is a noise, coming from as best I can tell, the power steering pump when I listen to the engine with the hood up.
Can anyone offer suggestions to help trouble shoot this. I have concluded that a replacement pump is a pricey item new (around $500US) and I would like to replace it in myself, if I can get a warmer fuzzy feeling that it is in fact the problem. I want to be sure it is the pump, don't want to swap out the pump and then find out the pump was not the problem.
I know noise is not normal, so I have a strong suspicion the pump is the problem.
What can the noise be from: bearings?, pump mechanism? Is this pump like an oil pump in an engine, gear style?
Are there seals that could have gone bad?
How to trouble shoot this is my question?
Anyone know of any High quality rebuilt power steering pumps?
Thanks for any info anyone can supply.
