no you don't need a wheel puller. all you have to do to remove the front hub is take off the spindle nut (remove the cotter pin to get it off) then pull the hub off. its easiest to do with the spindles on the quad. imo. hope that helps.
reded: i didn't have to use a gear puller. but my bearings weren't fried. and my spindles were off the bike when i did it. i just used a rubber mallet.
