What tool do I need to take out the rear Diff fill plug. I have an AMC 20 and I have tried almost everything I have and nothing will fit that fill plug. Thanks guys

For most axles just use a 1/2 drive ratchet with a 1/2 extension. Should come right out. If its the style that sticks out with a square lug I use a pipe wrench.

I have tried the 1/2 inch drive with extension, I have tried the 3/8 extension. My 3/8 is to large, but only by a little. Let me guess I do not have the stock plug....

no...I dont think you have the stock plug if the hole is THAT tiny. The AMC20's I have seen use the 1/2 plug. Thats weird that 3/8's is to big, You would need to find some sorta weird nut driver to take it out I guess.

THat is what I was afraid of. Actually it is a hex head a little smaller than 3/8s Where would I find something like that.

I wonder if Autozone would have the stock plug???
I bet I will have to get it from someone here or a junkyard. The thing is I need to get it out so I can refill the diff..

DO they even sell tools like that. I guess I can go to sears tomorrow and look for something that will go inside a hex head shaped hole that is smaller than 3/8's

Hey shadow, when I did mine, I just used a socket allenwrench. I don't remember the size, But mine was just a standard allenwrench. Craig

Thanks craig, that is a thought that ran through my mind. I checked all my allens and they were all to small, but a larger one would do the trick. At least that tool will be easy to find.

if 3/8 is to big you need a 10mm

uuhmn,iirc the amc 20 plug was a 3/8 allen wrench, the dana 44 front diff used the 1/2 square inset. prolly yours is either plugged with dirt or worn out.they put it in a hard spot to reach. i had the same thing happen to me on one of the 3 i had and replaced it with a 1/2 pipe plug from a hardware store for about 50 cents. to loosen it,you may have to drift it with a dull chisel or punch

Shadow, come on down to Falkville and we'll figure it out. I'm working nights this week, so I'm in the shop everyday.

Get you some of these.

I have an AMC 20 in my CJ.
find a bolt with a hex head that fits the plug. double-nut the other end of the bolt and use a wrench to take it out.
