I'm attempting to change the oil in my transfer case and axles, but can't find a 13mm (1/2") square driver for the fill and level plugs, anywhere. Can anyone tell me where to get one? Thanks.

 

At the end of a 1/2" drive ratchet or beaker bar......

 

just add a couple in extension on your 1/2" ratchet and your set.

 

Go to Sears, buy a 1/2" rachet and a short extenstion. Oh yeah, get a hand pump too.

 

Awesome. Didn't know if that would work since ratchets are usually rounded so the socket goes on easier. The hand pump I noticed when i looked up and tried to figure out how I was going to pour fluid in there.

As always, thanks.

 

All the 1/2 inch socket wrench handles I have fit the disco just fine.
