Question for the power steering gurus. I swapped my Saginaw box as my original was leaking and a rebuilt box was only $160. (I understand all the issues with the 3 vs 4 turn boxes. I am not concerned with that). I will eventually rebuild the other but for now a replacement made sense. Got everything reinstalled and it's like I have a manual box. With the old one I could start the truck and turn the wheel with one finger lock to lock. Now, if I'm not moving or don't have the rpm's up I can hardly move the wheel at all. I am at a loss for what is wrong. I bled the air out by lifting the front end and spinning the wheel lock to lock several times. It turns easily with no load on the system. Thoughts? Does this mean there is still air in the fluid? Doesn't seem like it as there is no more "foam" in the fluid when I check the level and it is not going down any further. Any help would be appreciated.
