I have done the UNTHINKABLE. I have removed a Brumby gearbox that has been rattling in the front diff when i drive . Appears to be on left. Jacked the front up and spun the wheels in first gear right front spun well, but left moved in spasms and rotated in slow stop start rotations. Removed the box and extracted the differential roller bearings with great care. The front axle drive shafts have no bearings now. Can I get away with heating and dropping in new roller bearings and resetting the Axles Shaft holder . If so can I reset the Diff and how. Trying to avoid breaking open the box.
