Differential Fluid Change

For the front diff. every 50 hrs. is not a bad idea if you have ADC. If not, then you should be able to go longer. I prefer to change all my oils every 50 hrs. Maybe excessive, but I like to keep it well maintained. You will need to use Polaris Demand Drive Plus oil in it. The drain plug is in the bottom of the diff. and the fill plug is on the front. The fill plug can be a bit difficult to remove and you might want to see if you can get it out before draining the fluid. That way you won't be stuck with an empty diff. and no way to fill it.
