Diff fill plug

TRChad · 08-31-2011, 02:30 PM

Sooo....was ready to fill the diff after draining all fluid. Manual says to fill through the Allen plug on the side of the clutch housing and fill until fluid comes out the hole on the bottom of the clutch housing. Looks like both of these plugs are 12mm....which I don't have. Question is, what is everyone using to get the 12mm plug out to read the fill line? Do I have to cut a 90 degree Allen to fit? It's super tight in there and can't figure out how to get out..even if I had a 12mm.

Thanks

You guessed it. I also use a 1/2 inch pipe about 1 foot long as a cheater bar on the allen wrench to get it loose.

Chad, any auto tool store will have sets of socket head(hexagonal) adaptors that will fit a 1/2"drive breaker bar to loosen the plug. They are realatively cheap and save a lot of slips, skinned knuckles as well as damaged plugs. One of the better additions to my tool chest i have made

Well both sets of hex head sockets wouldn't work. Not enough room. Ended up using the grinder and cut off a few inches on the 12mm wrench...then used a boxed wrench on the end for torque. What a PITA. Bottom line is ALL REAR END CHATTER IS GONE and shifts are like butter. Redline is the sh$t!!!

Chad did you add any friction modifier or just straight Redline? I read on the other forum how some had chatter after the Redline swap and added Ford or GM FM. I have 10 qts. of Redline and am ready to change, just seeking advise on the additive.
