You've most likely either got bad steering cylinders or a bad steering motor. It's probably 5 years since I had a motor in pieces so my memory is getting foggy. IIRC, most of the action happens in the bottom section of those things and they're a gerotor type of pump/motor. Pay very close attention to the end plates and their wear patterns... and also make sure that you don't force anything putting it back together or you can break some rather expensive parts. Yours kinds sounds like mine did after I broke (cracked) the commutator ring when I put it back together. Just look at it very closely. Beyond that I think I'd put it all back together and put oil in it except... instead of hooking up the cylinder lines... plug them where they come from the steering motor. Then start the engine and turn the wheel... or try to turn the wheel. I believe with the lines plugged it should act the same as the cylinder against it's stops.... so the wheel should NOT turn once the lines are purged. (Might be good to couple them together to bleed the system first, then plug them.) If the wheel does turn with the lines plugged then I would wager that the steering motor is bypassing internally. if everythign holds up tight... I'd expect a cylinder problem.
