i was riding my bro's scrambler for about 6 or 7 hours with my bud's one night in the snow. nothing was wrong with it. went out there and rode it about 3 or 4 days later and it acts like its in 4 wheel drive constently. it will kick in at about 1/2 throttle or more. it isn't a constant either. it will grab then let go,grab,let go, and so on. when i switch to 4wd it is a constant and even grab. i have never heard of sutch a thing. i thought the on-demand system might have froze or sumthin. i have a magnum 325 and it has never done that and i have rode it in the snow for longer and harder.i need some help. any suggestions(within reason)

 

Start with changing the hub fluid. If that doesn't work, post back and somebody that knows more than me might help you.

i have never heard of having to change the hub fluid. what might this all invovle.

 

Look on the hub, there is a 3/16" hex head bolt. Take it out, and point the drain at 6 o'clock. Let it drain a while. Fill it until it is full enough so that a little drains out when in the 3 o'clock position.

It might be a good idea to take the hub seal off the end, and clean it out with WD40 or brake parts cleaner.

Most guys in here recomend using Mobil 1 synthetic ATF oil. That's what I put in my buddies, and it cured his hub sticking problems.

 

Hey i had the samething happen to my scarmbler it happened this past week they said the on-dmand swith was shot and we had to get a new one but what is great is that they said the polaris would take care of it and all it costs is 58 dollers so go and check it out soon

 

If the oil comes out looking dirty when you change it, ride it around a while & change it again. You want to get as much gunk out of the hub as possible. It only takes like 3 or 5 oz. per hub, so its not like it will cost much, just the effort.
