front diff didn’t hold the spec amount

Hello everyone. I’m hoping to have some clarification on this…

I just got a 2011 550 Sportsman eps touring. I am slowly working my way through the fluids. Last night I changed the front differential fluid. The manual says that it should hold 9.3 OZ. The capacity was no where near 9.3 oz. I think it may have held closer to 5 or 6 oz.

Has anybody else had this issue before?

Thanks id advance,

Tim
