743B after replacing bad hoses under the cab I took it out to work saw another yummy fluid line on the ground frustrated I shut'er off and walked away to cool down lol today there was a large circle of fluid around both right tires grumbling I thought omg not another hose under the cab .. I checked everywhere with no luck crawled under and saw the right back axle was wet and dripping but its leaking dead center from the wheel and the frame on the .. TOP?? I felt it and it seemed to be triangular in shape lol what the ?? is it or what WAS there? strange!! anyone have a clue to this mystery? because she is still puking all over the ground lol

Not that I know of but pull the plug that is the oil leval if you are looseing hydro fluid into the chain case it is a bad seal from the case to the motor not that hard or much money

hmm hole still has me puzzled .. so behind the wheel is a seal? should there be fluid in the axle housing? where is the seal? is it at the wheel or deep inside the housing?

Are you looseing hydro fluid......the axle seal is just inside the axle tube.........pull the chain case plug
the hole is midway on the axle tube on top .. the other 3 left-front/rear and right-front do not have a hole .. this is the strange part .. how far inside the axle tube is the axle seal? if its less than 2" inside the tube its not the seal

Just guessing here but think your motor seals to the chain case are leaking and it is looseing hydro fluid into the chain case and some yahoo drilled a hole in your axle tube

If the one of the wheel motor carrier seals is leaking then oil will leak into the chaincase under pressure and overfill it. Once it gets too full the oil has to go somewhere. I don't know why someone would drill a hole in the axle tube. Maybe its a rusted spot that just blew out from the pressure.
