hello i have the same atv and i am trying to put in the parts my self but i can not get the outer part of the bearing out of the swing arm

 

its tricky. Ive done it twice.. you need a torch to heat it up (weve done it till its glowing) then u need to stand by with a good strong flat head screwdriver and hammer and kinda knock it out. or sometimes, we had to use a "wiz wheel" and actually cut thru the outer bearing, then heat it up and beat it out.. its tough..good luck
