Has anyone ever cracked an AMC 20

Has anyone ever actually cracked an AMC 20 housing or tubes? I'm looking to build a rear axle but don't know for certain yet if I want to rebuild the 20 or pick up a dana 44 instead. I don't currently or plan to do any severe wheeling so I assume I would not be throwing money away if I decided to put the money into the AMC.

my 2 cents. . . . .I would think a 20 behind a 6 cylinder that does not see a lot of off road abuse would last a while especially if you use one piece axles when you go through it.

Let me rephrase. I use my jeep alot off road for hunting and camping trips. I don't climb the sides of cliffs and what not though. That's what I call severe wheeling. I do get into some hairy spots from time to time. In other words it's not a strictly pavement jeep. It's just that I read so many people swapping out the AMC, IMO mostly due to the two piece axle I was just curious if anyone had actually had a housing failure with one.

Most people who are hardcore climbing get rid of the AMC 20, but I have always heard that if you weld the axle tubes, truss it, and get one piece axles there are actually really tough.

I have a mild v8 with an amc20,all stock even 2pc axles. I have put it through its paces and have yet to see any failure from it. I'm even running 33 inch tires.

If your Jeeps not leaking it's out of fluids.

x2 - Weld the tubes to pumpkin, 1 piece axles and keep the tires under 33" and you'll be fine. The internals are stronger then a 44. If you want 35" tires or more or want to due more extreme stuff, add a truss. The weak spot is the 2 piece axles and thin tube walls.

I've never seen the housing split, but I've seen the welded steel tubes lay open down the seam before.
