I've searched the forums and looked at the most of the threads about the rear axle.

Seems like everyone's fill plug was a bolt.

Mine is some sort of plug bolt thing that fits a 1/2 ratchet.

Well, it was a bitch to break it loose, and now that I have it keeps spinning and won't come off.

Did I miss something or is something totally wrong?

Looks like the PO welded a socket to the bolt and rigged the bolt on there.

I finally got it out with some tapping of a hammer and there's no threads on the bolt.

now I have a bigger dilemma.

And all I wanted to do was change the diff oil.

Here's my ghetto fix to this dilemma.

I bought a M18-1.5 plug at auto zone.

Borrowed a 18mm spark plug tap from a friend.

Tapped the hole.

The kinda jerry tapped it with the plug.

Come on and off perfect now.
