480c Backhoe valve assembly

Does anyone have any hints on the easiest way to work around backhoe valve unit? My last big leak is coming from this area, I noticed when I deadhead the right side stabilizer it pores from the valve area. Hopefully is just a hose, but I am looking for hints as to the easiest way to get to it, it comes in from the front side of the valve.

I was thinking about taking the rear tire off and see if I can get in there that way. Or park over a ditch and crawl underneath? The manual wants me...
