Gator I see now that replacing your front steer axle would be a major refit to the tractor,with where the diff pumpkin is located in the front frame section..at least you made them removable with the uboltt design..mine are welded into the frame permanently..I thought long and deliberate about doing that thinking I would never break 30spline Dana44 axles..the only real drawback for me is they are semifloaters so when you break one it destroys the wheel bearing and seals quickly..I have some spare axle shafts to make up new ones but I have to say its been doing OK lately..your machine comes in a LOT heavier than mine..I think that and the new lugged tires will cause more axle problems for you.
