Removing Stripped 2004 Front Differential Drain Plug

[Hoffbauer2]

The Front Differential drain plug on our 04 GX470 is stripped.

I have tried the typical extractor tool with reverse threads.... but it won't budge.

I'm afraid of cracking the differential case if I go at it with a hammer & chisel.

Is there any special tool to utilize on this drain plug...??

Have you heated the plug with a torch ? Heat works wonders.
