It is not a belt slipping, or belt misalignment.
But....I did not bleed it before I filled the pump, since I did not think I had to since it has a low pressure return line to the pump. OK - I screwed up, but the pump is filled all the way (I overfilled thinking that it was a low fluid problem). How do I bleed this thing now ? Can I just drive it and it will eventually work the air out itself ? It makes no noise when you are not turning the wheel in one direction or the other.
Thanks for the responses.
