Anyone know what size socket I'll need to get the rear diff. fill plug out? (Not the drain) Looks to be larger than my 1 inch socket. Anyone drained their rear gear oil and know the size off hand? :)

I may be way off base, but something in the back of my brain would cause me to guess 24 mm...or is it a little bigger?

I asked the same question on the other forum and got my answer. 30 mm. Like a dope I said drain plug instead of fill plug but I got my answer anyway. Thanks though LA. :)

Yeah, I saw the thread. I remembered that one of the plugs was bigger than any of my sockets.
