front axle differential seal leaking. already had one changed under wawrranty. Off warrenty now with 400 hrs on tractor. When talked to mechanic he said they sometimes leak because the axle filler plug is sealed so tight that it builds up pressure and blows past seal. It is sealed so tight because the tractor is used in places where axle goes under water so this needs to be sealed. Has anyone put a air vent in the filler plug as most of us dont need it to go under water. I am thinking of threading the plug and venting with a proper oil vent would this be a prob.
