I upgraded the bent spindles on my mud mower with new ones that have been braced. Plus they now have tapered roller bearings. It's a great heavy duty mod for a mud mower or for a garden tractor that has a loader.
I’ve been thinking about how to put 4 on 4 trailer hubs on my build. Went out to Northern tool and picked up some 1” spindles and hubs today, before I found this video. Seeing how you were able to weld the factory spindles into the new trailer spindles gives me confidence it’ll work. Keep the videos coming, nice work.
