New to the forums page here, always get great info here and finally joined. I have a question about my grandads Ford 8N. He has a small shredder on it, and started the tractor up, raised the shredder and walked away from it for a second. All of a sudden he says was a loud pop, the shredder goes down to the ground, and what appears to be a few gallons worth of fluid pours out of the back right hand side axle down the wheel. The tractor still idled smoothly, but he turned it off and says it will start just fine but just don't know what happened inside there. Just a simple axle seal or something? Before i just start taking stuff apart, does anybody already know what this is? Or where i should start on this? Thanks!
