Alright boys a lot of you seem to have a wealth of knowledge so help me on my gear box leak. It's a c7000 with a non metric gear box that's leaking where the steering shaft goes in... I've got 3 of these, ones leaking ones seeping and one looks good...Are these gear box leaks fixable? Looks like I may be able to pull the shaft pull the old seal and drive an new one in?
