Fill hole for oil to the rear diff?

[Rodimus_Prime]

is the fill hole on the rear diff cover? There's like a rubber thing on the cover I thought it was supposed to be somewhere along the top of the diff?

Fill hole is on the middle pass side of the rear end above the horizontal rib. It will have a square hole that a 3/8 ext fits in.

On a TTA?

I filled mine through the rubber plug. That is the fill hole.
