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?
