I just detected a leak, a slow drip, from my front driver side compartment from the circular plastic cover plate on the steering gearbox. It's definitely coming from under the circular plastic cover. It is either not been dripping for very long, or intermittently or not very much because I haven't detected it on the ground, but it is a steady drip every 10 seconds or so.
I see rust...
That would be the shaft seal leak that has been discussed here a bunch. Some just replace the seal and others have the unit rebuilt. Some DIY others have the job done by credit card. Do some searching and reading so you can figure out which way you will want to go for repairs. Look up Shepard M-100 here and you will find lots of stuff.

There's a place up in your neck of the woods that rebuild these steering boxes.
That would be Redhead: Red-Head Steering Gears (https://redheadsteeringgears.com/)
Very good reputation for actually blueprinting as well as sealing the Sheppard box to reduce play.
So as many skills in life,
Blueprinting is more than most understand. In these gearboxes there are large ball bearings that take up the free play in a worn box. They come in different size sets. Too loose and there is too much free play in the steering. Too tight and the is steering is tight and bound up. A good technician with learned skills can install the correct sized bearings to take up the free play and make steering smooth as silk. I you were happy with the steering currently you may not gain much. But if not you may be amazed at the improvement.
There is very little play so I will go with new seals. Thanks for the help here.
Dave, You have the leak on the "lucky side". That seal is fairly easy to change on the drivers side of the steering box.. You can buy the seal from Red Head as well as others on line.
That plastic cap is magnetic. It'll pull right off and you can seal what your facing. The biggest issue I had was prying off the plate after removing the bolts. It was a bear to pop off. I used a hammer and metal chisel to LIGHTLY pry it off. Then just a matter of pulling the old seal, clean up, and install the new seal. I put a catch can under the unit and only lost a couple of cups of fluid at most.
It's a pretty easy DIY job.
