i took mine to the dealer and had them torque it to 80 lbs but it didnt fix the clicking/poping. the fix from polaris is a shim and to locktite the bearing in place. they say the bearing walking/moving is the cause of the noise and the shim will stop it. the cause they said is big tires and abuse but i had 4 hours on mine and didnt abuse it. all in all i love the hell out of it and i will drive it like i stole it as soon as the break in period is over. i will also keep you posted on the shim loctite thing as soon as the shim comes in bla bla thanks for the previous information from all you guys!
