ATV won’t move except in 4 wheel drive

[Steve M.]

I have a 2009 Artic cat 700 4 Wheeler and it will not move except in 4 wheel drive. Any ideas? 

 

Thank you, Mary

What happens when you try in 2wd mode? does it feel like it wants to move or do anything?

Look down at the rear driveshaft, is it turning?

Nothing happens, just revs up , like it’s in neutral

The rear driveshaft is turning

. It is either  splines have worn out on the  pinion shaft,or possibly  between the  crown  gear  and output to the axles. . When  you  have it in 2WD,  the rear differential is what moves your  machine . The reason  it moves in 4x4 is because the front differential   is pulling the  machine along. You'll  have to  take the  rear drive apart to  find  just what  is gone .
