Rear end drain plug

drill a hole in the bottom, tap it 1/8 NPT and install a brass drain plug.

Saw this in another thread but didn't want to hijack. When you put the plug in since it won't bottom out, do you put thread sealer or Loctite on it to keep it from working loose? Got my rear out now and was thinking that would be a good idea. Also, why a brass plug? Couldn't you just use a 3/8 or 1/2 inch bolt, cut off so it didn't stick up into the housing?

Thx

I did. I used a 1/4 inch aluminum pipe thread plug. Drilled and tapped, apply some Locktite and haven't had an issue.

Just be sure and offset it away from the ring gear.
