Mine did the same, probably just need to change oil in hubs. ie. take the caps off and drain oil, fillerup to 4:00 with ATF. I think they use a low grade o-ring on the hubs because they seem to swell so it's sorta hard to get back in. Use a little grease on it and make sure it doesn't pop out of it's groove when you install.

I don't understand how the level or the quality of the oil in the hubs would affect anything other than bearing life? I did change it in the fall, I used polaris recomended hub oil...
I live on a lake and it is just now thawing and it is a blast to rip around on wet ice, driving in 2WD is way better to handle unless slipping so I switch in only when I need 4WD. so like in the past month or two it won't shift out of 4WD (mud, water, snow and ice is flying off all fours but when I'm boot'n over to the neighbors or what ever I have to put up with 4WD steering and all the while the the switch is off.
So what now?
Where is the celanoid that shifts the transfer case to the front end??

On the 500 sportsman's you always have power going to the front hubs coming from the "transfer case". There is a Hilliard clutch in each of the front hubs that is magnetically engaged to enable 4wd. The wrong oil, low oil, worn plates, over tightened hubs , and some other stuff can cause problems like you describe. You would be wise to invest in a service manual if you plan to work on it yourself.

The above comments are correct, one other thing that can effect the disengagment is a streached retainer spring, this go's around the clutch rollers and is what disengages the hub when the power is cut.
I have over 5,000 miles on my 96(very hard miles)and have never had this problem happen to me, I do change hub oil at least 2 times a year.
Keep in mind the nature of this hub, the reason you should not over fill the hub is due to the expantion and contraction of the oil, the ATF has no problem heating up and expanding (closed system no vent)
the preasure can build in the hub or be pushed past the seals. Now the problem part, the contraction, as things cool, a vacuum is formed in the hub. This can happen quickly when you do a river crossing, etc. this is where the dirt and grime comes from. The oil is a key player in the release of the clutch, KEEP IT CLEAN, I have worked on others front ends that have been hanging up, every time I pull dirty / watery oil from the hub. It is my opinion that the only way to change the oil is to pull the cap, and better, pull the whole hub apart, this is easy and fast after you have done it once or twice. Jump in and understand the workings of your ride, you will not be dissapointed.
