Kubota M4900 Axle Bearing Replacement - Tear Down

This is a real-time teardown of a failed front axle steering knuckle on a Kubota M4900, filmed after a gear oil leak during haying season. The owner disassembles the hub, finds disintegrated ball bearings and scoring throughout the ring gear and housing, and walks through each part removed. It ends undecided on repair approach, with parts still to be ordered, so no reassembly or fix is shown yet.

An owner-operator documenting a real repair on his own longtime tractor, mid-diagnosis rather than offering a finished how-to.
