Do you guys change all your fluids after haspin or not I'm already going to change the front and rear axle.

Not even sure what Haspin is. Some eastern mud hole, I presume????????

I figure you are woried about water in your diffs or engine oil??? When in doubt, just do the safe thing and change it!

haspin???? It depends on your quad, and year. Some newer ones, like mine are sealed up tight. I have checked a couple times and they are watertight/dirt tight. If you feel uneasy, its cheaper to replace the fluids, instead of the worst alternative.
