i have a 1952 8 n which keeps losing steering lubrication. remove the plug on the steering column fill with oil and deal with the mess ( seems to be leaking at the sector shaft seals ). I have seen the how to sections here but i am confused. The manual on the late model column shows a fill plug at the base of the steering gear housing. Mine has a fill plug on the engine side of the steering tube near the top. Also conflicting views on original style oil versus grease and grease fittings.Any help would be appreciated.
