bobcat 773 hydraulic leak into bottom right only when using lift arm

[netgypsy1]

Raised the cab while running and no sign of the leak. Only seems to leak when using lift arm but can't figure out where it's coming from that it goes into the bottom??? Loses more than a gallon in 30 minutes so you'd think it would be obvious but I cleaned out the bottom and can't see where it's originating.
