New here so please be gentle.. Lol. My 7753 is leaking oil on the inside of the tire so I would assume it's time to change the axle oil seal.. I pulled the tire, removed the 1 1/2 bolt that holds the hub, removed two wheel lugs and put a puller on it.. ( this is what the manual tells you to do ) cranked down on the puller and this hub does not want to budge!!! Even with a couple of blows from a 8lb hammer.. Nothing!!! Am I missing something? If I grab the hub, pull and push on it there is about 3/8 of an inch of travel back and forth.. Might it need bearings also? Oil seal was only $12 from bobcat but I think I burnt about $100 worth of patience trying to get that hub off.. Any info would be gladly appreciated
