Axles and hubs, that's what has me in a knot this morning. Front left axle on the 415 I cannot get the hub to slide off. Is there something special about getting the hub off? Undo the bolt, take out the setscrew pull off with a puller isn't it as simple as that? The goofy thing will not budge. A little heat helped loosen the Loctite on the set screw, what am I missing?
