I've been trying to dig up information on the manual steering gear box but can only seem to find power steering conversions. I'm trying to update the steering on the 40 and have everything worked out except for this component. What grease/oil goes in it? I think I remember people using red Mobil instead of oil. The FSM doesn't seem to show any wearable components except for one gasket which I can find from SOR. Has anyone done this? Any threads on it? Thanks in advance. Mine has leaked all over the frame.
