I use this from parktool but there is cheaper on amazon but its worth saying again it is a LEFT HAND THREAD and rember the tool has to fit over the axle the one pictured above wont
So how much grease do you think should be inside? Mine had a small amount on the gear cogs and thats about it. I would have thought too much grease inside is gonna get flung about every where

Err ok to the right loosens it to the left tightens it at least it does on my m510
I only mention it cos it caught me out for a bit
Hope you get it undone
