A lot of times the steering shaft thrust bushing fails allowing the shaft to work up and out of the lower seal area, this lets a small amount of oil leak up and out the top then down under the tube and onto the floor,, also there is a check valve that can get weak and let too much charge oil enter the valve, forcing oil out the seal. To service it you can remove the steer wheel and hinge bolts/hoses and the column will come down out the bottom with out removing the dash. I can re-work it here or help walk you through it when your ready, I have a couple here now, If I can I will take a few pictures to help explain it all...
