ok i live in va and as you may know we was hit with a snow storm i have a 2006 honda rancher 400 at i had to ride it out of were we live to get out it was slush when i went out and it started snowing hard so when i got done rideing i was rideing fine but the next day my back wheel on the brake side is locked up it wont move the temp outside has been in the teens when you put it in drive and give it gas it trys to move but wont and the other side tryes to move could i have set the park brake and it froze or soomething froze in or around the wheel the rim does have some ice in it surely the rearend is not froze and doees the 400 have a sloid axle or a 2 pice inside that black tube

 

Get it inside and warm it up. 99% of the time some water is just frozen and locking things up.

 

I have had two quads do the same thing. On the straight rear axle quads with drum brakes, the seals don't do too well. The drums get water in them and freeze when it gets cold. Like mentioned above, put some heat on it and it will loosen up. Take the wheel off, pop the drum apart, drain the water and clean it out good. Put it back together and you will be good to go.
