what tool to change diff oil?
 

what tool do you guys use for the diff oil plugs?
Just wondering what size allen wrench it is.

A 3/8" socket extension?

yeah just stick the square drive in the plug.

Well as long as were talking about diff drain plugs, anyone have any suggestions on how to get mine out if the 3/8 square in the plug for the socket is now round?

Buy a new plug, then drive it to someone who can weld that socket extension in there :)

Well I suppose that would work... But I think my dad would be pissed about his socket extension :D

hmmm. do they make ez outs that big?

what ever you do....do not tap it out. Bouis has a wonderfull Idea with welding it. I had a friend have this exact same thing happen to him...He used an impact wrench to put it back on(don't say anything I don't talk to this guy anymore) so he used a tap to pull it out. Think about how wrong it is to run a tap in a diff. It lasted about 350 miles until all gears were completly F'ed up

Yeah, Ill just buy a cheap extension at wallmart and get my buddy to weld that on. (thats all those stanley tools are good for IMO)

Just weld a big bolt in there then you don't need a new plug.

that would actally be a great idea. just about half an inch of the thread and make the head as flush as possible. that might just be a great idea!

also, you could use vise grips to twist off the plug, but afterwords, get a new friggin plug

hmmmm. that is a good idea:) very inexpensive
