If the tractor is a 4 wheel drive you use 80/90 weight gear oil in the front axle. If it is a 2 wheel drive tractor it has bearings in the hub that have to be repacked every 2-3 years. I had a 2 wheel L-1801 and repacked the bearings every 2 years. All that was required was a cotter pin and a new rear seal. I simply took the old seal in to the dealer and had him match it and it worked fine.
We all make the mistakes and that is part of learning our tractors and since it was not damaged you learned that gear oil does not work.
