Don’t go by the Operator’s Manual. It says to pull acorn nut off and pour hydraulic o il down the steering shaft. That will only get you a mess and wasted oil. The steering gear lube ports are on the RH side of the steering shaft behind the dash on both styles. The early box uses a 1/4" NPT plug and the late box uses a 7/16 hex bolt. Both still are not easy to get oil into. I modified some for both with new NPT plugs and new hex bolts then drilled thru and tapped out to insert Zerk fittings to make lubrication a much cleaner and easier method. I also use cornhead grease but some don’t like that. I have no issues with it so to each his own. Chances are the bearings and seals are gone so a steering box rebuild is in your future.
