Its the housing, I saw pieces of it on the bolt threads themself.

It's a gut wrenching feeling isn't it

A rubber plug should work. I would watch it carefully though, at least at first. Make sure it doesn't fall out when the diff housing heats up and expands. Also I would do an oil analysis after running with the plug a while, to make sure the plug and the oil are not chemically interacting.

But a plug is what I was going to suggest when I saw the thread title....

I don't know if they come in the right size, but I would try a pipe plug from the local hardware store. It's essentially a rubber stopper with a washer on each side and a bolt running through it. You press it into the hole and then tighten a wingnut to hold it in place. I would replace the wingnut with a locking nut with the plastic insert.

I posted the same info when esracer stripped his diff.

QuickSteel Usage

QUIKSTEEL can be used to rebuild, reshape, and repair almost any type surface including steel, iron, copper, brass, bronze, silver, aluminum, exotic metals found in racing bicycles, wood, glass, ceramic, fiberglass, boron, fiber-epoxy products, masonry, concrete, and many types of plastic.

QUIKSTEEL's high temperature rating of 500&degF (260&degC) continuous and 550&degF (288&degC) intermittent temperature range provides numerous additional applications where high heat is involved.

Because it is a putty, the repair can be made in vertical or horizontal position, overhead, etc. QUIKSTEEL does not run or drip and sets-up in five minutes. QUIKSTEEL hardens like steel in 15 minutes, and fully cures in one hour.

Because QUIKSTEEL has a hardness more than twice the hardness of pine wood, you can process QUIKSTEEL any way you can process steel or wood. You can turn it on a lathe, shape, mill, machine, drill, tap, sand, and paint.

QUIKSTEEL is impervious to chemicals, solvents, oil, and acids, including battery acid and can be used to repair batteries. QUIKSTEEL can be used to make repairs under water or within fuels or solvents.

The rubber plug was to big didnt work. I ended up using some sealant around the original bolt and tightened it lightly. Its holding so far after a 40 mile drive. I'll see in the moring if its leaking. Im more worried aout the chunk of metal I found. Better start diff shopping now.

Why not drain the fluid and clean out the housing?

Updated with pic of metal shaving found on drain bolt. First post.

Without a reference it's hard to tell but that does not look like threads from either the housing or the fill bolt.
