    My seal went on my steering gear and all the fluid leaked out smoking the old pump. I replaced the pump with a reman one,and the gear with a good used one. Filled with atf, fired up and it works great, just whines with any steering or hydroboost useage. Its freaking loud, you can hear it over the 6.9 cackle. I have the ps running to the hb, then the rerun tees and goes through a fin and plate cooler and back to the pump. Had this setup on 3 other pumps. Any idea whats causing it?

    It could be foaming fluid. Jack up the front and remove the return line into a bucket and flush the system. Turning stop to stop 5-6 times.

    Add PS fluid while turning bump to bump. You may still have some foaming. But let it sit a few hours or over night. And should clear up.

    With hydra boost. you may want a buddy to help add the fluid. If your old pump shot crap. You may have small bits of pump in your gear and hydra boost.

    What fred said...need to flush and bleed the air out.

    You might have a bad pump, so if flushing and bleeding the air doesn't work, smack it around, tell it to quit whining, and act like a man:D
