Ford 9" oil leak

[Texasdoc]

Hopefully this helps...

All the receipt shows is the following. There are no other brand names other than Moser. I can't be sure that is what it is, but that is what the receipt shows. Not sure what Torino BB ends are but Google suggests they are end flanges.

Moser Axle
3.70 gears
31 spline LSD
11" brakes
Torino BB ends
Vent, drain plug

I looked at the 3rd member (carrier?) and saw C5AW. No "N" stamped on the front. Single ribbed case. No drain/fill/level plug.

The housing looks like this:



NOT LIKE THIS:

This pic should give a better idea of lube height/level in the unit, note the level hole is a bit lower than the axle tube diameter so filling until it runs out the axle tubes will be too high, I dont see anything other than removing the diff head assy & fitting a level plug in the axle housing, if it has not got a drain plug you could fit one of those as well, You could drill & tap for a 1/4" npt type taper plug in the axle housing rear cover at the correct height with some grease to capture swarf etc, or better still drill a small 1/4" hole & use a taper punch to 'flare' the hole inward prior to threading for 1/4 npt to gain a couple of threads.
