Diff oil ?

[steveo]

Hi what type oil do you use in the diff! and how much is needed to
fill diff, do you just fill till it starts to run out of the hole ?
took my arm off and had it powder coated,whilst out some oil spilled out, thanks steve.

It's just GL5 gear oil, just filled to the top of the filler hole, don't overfill, it doesn't take much.
