About to change the wheel bearings on my 06 450 Sportsman. First question is what is the axle nut size? Unfortunately most of my larger sockets are metric so I'll have to purchase the correct size for the axle nuts. Nest question is, if the Wheel bearings are good, can I assume there should be no play when grabbing the wheel and rocking it from side to side? I've got the wheels off the ground and the play is there but its not a huge amount. Maybe 1/8" or so side to side. For comparison I checked my Hawkeye which has very low hours and there is absolutely no side to side play.
