I own a 01 scrambler 500 4x4, today i was riding when i noticed that the front left wheel engaging in, spinning as if it were 4x4. When I locked it into 4x4 it pulled even more, when i have it in 2 wheel drive it really pulls hard. Any suggestions as what this could be, any help or info would be greatly appreciated.

Thanks

 

Try changing your fluid. You may also want to try Mobil 1 Synthetic ATF type F.
