You need to do a video on removal of the bearing. Most mates are clueless as how to do it. Use a large knife pulled connected to two threaded rods and screw plate with sharpened bolt pushing on end of axle in small hole. Tighten bolt to pull bearing off. After new seal has been put on axle drop bearing down axle shaft and use a long heavy steel pipe and slam it on or press it on with an axle bearing press.
