I noticed this morning my MF 7 sprung a leak on the axle and emptied on the garage floor. I downloaded the service manual and it covers dis assembly/ assembly but doesn't mention anything about seals so I'm coming to the experts before i dig in. Can the axle seal be replaced externally? Also, no mention of a bushing/ bearing. Same question. I do have a spare transmission to swap out if this needs a complete overhaul. thanks in advance!
