Power Steering Noise

I had a couple of similar problems with belt squeals. I was only able to get rid of the problem by bead blasting the pulley grooves to give the belt a bit more bite. As the belt wears in the pulleys it will probably get slick enough to slip again, but, should last a few thousand miles. Oh, I also had a couple of engines where the fan clutch was locked up and had that same problem. You may want to check that on yours. I tried to use one of those clutch fan eliminators on my tow truck to get more air flow from the fan, but, it squealed so bad at higher RPM's, that I had to take it off and go back to a clutch.
