Kinda of stump as I want to get it right the first time but is the drain plug located on the bottom or is it on the side of the axle. Looking at the manual it shows a drain plug but no real location to it. If it's on the bottom, what size socket will I be needing as it seems to be bigger than all the other sockets I currently have.

 

It's on the bottom, the one on the side is the filler plug. not sure of the size. see attached pic. #4 is the drain and #2 is the filler plug.

 

Thanks for the diagram, just wanted to make sure just in case.

 

Think it 17mm. Takes about 1 litre of oil if i remember rightly.
