Default Help removing a corroded differential fill plug.

The Fill Plug on my differential is so corroded I cant tell whether im supposed to us a 10mm allen head or a 3/8 socket head in there to get in out. Can someone tell me what the correct tool is to remove it before i go tap something in there with a hammer, and If that doesnt work I dont have access to a welder, would tapping as much of it as i can with a left hand thread and threaded a bolt in there work to take it out.

You just need the ratchet (3/8) to remove it

It was a no go, the plug felt rounded out and anytime it would grip, it would slip. Now what?

If it is a no go try drilling a hole in the bolt and use one of the reimer tools you get at a hardware store they are great for taking out broken and siezed nuts. I forget what the tool is called but a hardware might know the tool.

Try getting some wd40 or pb blaster around the head and let it soak into the threads

Yeah its called Ez-out or bolt extractors. The key is to make sure you drill through the bolt enough to give enough surface area so the extractor can grip enough. Other wise the bolt extractor is just gonna strip it out more.
