AMC 20 axle

Just lying under the Jeep again for no particular reason (I tend to do that quite a bit now). I decided to find where the oil filler plug on the rear diff was to change the gear oil. I couldn't find it but I did find "4.53" stamped on top of the diff housing. Does that mean I have 4.53 gears in there and where the heck is the filler plug???

You need to lay a wee bit farther under the Jeep to see the fill plug. Crawling under it just far enough to escape the ol'lady for a few moments ain't far enough to see it... ;)
It's not in the cover but on the forward/driver side of the housing. Don't know what those numbers mean but they aren't the ratio. The ratio is a letter code; B for 3.31's or D for 2.73's stamped into the pass side boss next to the dowel hole.

Seeing as her family is in town for the next two weeks, I think I'm going to bring my pillow out with me, the wheel chocks aren't too comfy. thanx for the info on where to find the plug I'll be under there looking in about 45min :D

I just took off the rear cover to replace a leaking gasket and was wondering how much gear oil it should take fill it up.

I was just replacing a leaky gasket and was wondering how much fluid the rear end needs? Any help is appreciated.

I believe the Chilton's says 5.5 pints (About 2.5 bottles). The book tells you to fill it until it starts dripping out the fill plug hole.
