cool hubs

just service my cool hubs over filled level is between full and max . will this cause a problem.

If they are UFP oil hubs , the level should be to the first or second thread at the bottom of the fill hole. leave just enough room for the fill plug...Im not sure about other mfgs, you might want to read the owners manual...

they are ranger cool hubs i think manufactor is tie down the level is above max line but still has a gap of air from the top worried about gas building gas and pushing oil out of seals would you take wheels back off and drain a little or will they be alright

I would do what they tell you in their owners manual...
