Here is a part I repaired for a fellow a while back. The tractor had continued to be used after the wheel bearings had failed and the front spindles were severely damaged. The repair involved welding the damaged areas to fill in the worn away material, then machining away the weld to restore the bearing surfaces to their original sizes. I was not able to remove the 3 foot long steering shaft from the spindle assembly so it made turning them back down a difficult task.
