Well if it was me I would. If you dont want to just be careful cause water is heavier than oil so it will sink so you cant really tell how much water is in it till you actually drive yer brute around in 4x4 to get the water mixed with the oil. That will tell ya how much water is in it. If its milky at all change it. Kawi calls for 1040 motor oil. I use the kawi brand oil in mine. Never had a prob with its performance. You dont want that water, if any is in it, to sit in the diff cause it will rust yer bearings and pit them. Then yer in a whole new world of hurt.

That's right 10-40 in the front & tractor hydraulic fluid in the rear.

It takes .47qt for the front. Its a slow go process. I was told after the front diff is drained raise up the right side of bike, with a jack or ramps. It makes it go in faster. After I fill it up I ride it around for a few minutes in 2wd & 4wd forward & reverse. Then change it again to make sure water is out. It may take a few time but u will get it all out.

As for the rear I can't remember how much goes in. Just fill it til it runs out.

I actually have an oil can devoted to 1040 kawi oil to do the front diffs. I have a piece of tygon 1/4" hose on it since its a pain to get any funnel in there. Goes a lot faster. I know for a fact the rear end takes a quart. I drain the rear ends overnight and in the mornin I put in a whole bottle of the wet brake disc oil from kawi. Takes the whole bottle.

i found the way i like doing it is with cap that has a point and u cut off fits rite in the breather hose and i use a pint containerand it work perfect and quickly but take out the fill plug so u know when its full.
