How to remove stripped rear diff drain allen bolts?

[audiquattrot]

The ones on my car were rusty, and are stripped. Any way I can remove these so I can change out the rear diff fluid? Maybe chisel them out?

Any advice is appreciated. thanks.

Chisel is the way to go. Or large vice grips, but the fins on the diff interfere. I've done it with a chisel a few times though, just be careful not to hit the diff cover itself, but you have the sealing ring there as well as a buffer so that shouldn't be a problem. Make sure you have new plugs and rings that's all.

I've used torx sockets for stripped allen bolts before too. Just get one a little larger and beat it in with a hammer.
