So I had time today to dig into the tractor It was pretty easy to remove the front axle. Four big bolts. Two in front of the differential and two behind. Disconnect the steering knuckle on the left side and two people can roll the axle out. I popped the cover on top of the axle and quickly saw the 6 bolts that hold the ring gear onto carrier were all sheared. Unfortunately I had to disassemble the whole differential to get the ring gear out. Next weekend I will work on drilling out the broken bolts and getting it back together. Not an expensive repair but a little time consuming.
