i have a 1998 500scrambler 4x4, after going through deep mud and water my 4 wheel drive started acting up REAL bad, pulling really hard. i got it home took hubs apart and cleaned everything and filled back up with polaris hub fluid, everything looks mint in there i put in new armature plates last month. after cleaning it still pulls not as bad but still really noticable. i even tryed unhooking the wires going to the hubs and still the same. can anyone ofter any help on this???????
you would think it would be either a bad bearing, or that side awd sticking is usually the cause.like mentioned, try jacking it up and roll that side to see whats happening??
here is one thing they mention. as well as a Pole clearance of 0-0.001" . Also you castle nut can,t be tighter then 12'- lbs.

After awhile the armature plate will gain slight magnetism from being around a magnet so much, this will cause your 4X4 to be very erratic. You really can't do harm to put new armature plates in when you service these hubs. Although if you would like to try and use what you have hold your armature plate to a piece of steel and see if you can feel any magnetism at all, it will be minor, if you can you either need new ones or you can try a suitable de-magnetiser.

Axle nut not torqued correctly or residual magnetism would be first.
Are all of your tire pressure set correctly? That machine had 1 inch larger front tires to keep the AWD clutch overdriven. If the fronts are soft or or rears overinflated you can get closer to 1:1 speed ratio. Well with another sip of coffee and a few more braincells working.... it wouldn't matter with AWD off.
Lost!!!!
