I deleted the vacuum from mine . its to easy to get out and turn the hub. I want to get warn hubs because the factory hubs are junk and the ybind. I have pulled mine and cleaned them up and re-greased them and the passenger side is to hard to turn. if this happens until you can get them replace grab a 2 inch pvc 90 % pipe and slot it and you have a nifty tool to turn them. no need to struggle or your head into a wall.
