Help with small Hydraulic leak

So two weeks ago I took the Family on a 4,000+ mile trip..It went like this Corpus,Houston,Memphis,Nashville,Louisville,Mackinaw City,Sault Ste.Marie "Canada'',And back Home to Corpus Christi.. After parking in our drive way to unload I noticed a wet spot ''small'' on my driveway so I started to scope out the source.
What I found,I have a Hydraulic leak on the side of the steering box,It looks like a weep hole, like you find in the bottom of a waterpump. this flat plate with the weep hole is plastic and bolts back to the gear box using 8 bolts..I did check the level in the main Hydraulic tank and all was good...
My question is this, Can I pull the 8 bolts,Fix whats leaking reinstall or pull the steering gear box for a rebuild?? Please see picture

Thanks for any input

I recently had Alan Lassetter at his truck repair facility in Channelview, TX, pull the plate in your picture, replace the shaft seal that was leaking and the O-ring that seals the plate.  The labor was $259 and the seal kit was $82.  In and out in 3 hours.

The plate has a large bearing carrier and bearing extending several inches into the case with the pitman shaft riding inside the bearing.  Lots of muscle power to remove and install.

Some fluid will leak but can be topped off to finish the job.  If you do the job, place a catch pan below the steering box.

Chaulk Truck parts in Houston has the seal kit, rebuilt steering boxes on the shelf and will rebuild yours if asked.

Contact me at jrlegett at gmail dot com if I can assist you contacting these folks that do a good job of helping me.

A skilled big truck repair place in Corpus should be able to do the same for you down there.  Our steering box is on lots of big trucks.

Thanks Rudy,, I'm happy to know it looks like only a $400 job and not a $4,000 Cleaning... I'm Always in La porte and know the area very well so If I can get this guys# from U I'll just let him do the repair on one of my monthly trips..
I have no other leaks but wonder if this guy rebuilds the fan motors and Hydraulic pump???  I would hate to blow one of these seals on a out of state trip. With 16 year old seals I worry sometimes
