Replacement for AMC 20 rear axle

It seems that my friend just nuked his AMC20 axle. We haven't had time to take it apart but there are some big dents from the inside out on the diff cover. Depending on how bad it is how expensive is it to get new gear or to replace the whole axle. He was also wondering how much it might be to swap something else under it like a Dana 44 or something. By the way it is a '79 CJ7. Thanks.

Scout 44 is a bolt in with the same bolt pattern. Only thing needed is to move the perches. For info go to: http://www.jeeptech.com/convaxle/

Re: Replacement for AMC 20 rear axle

your buddy is probably gonna need a gear set + set up for sure ( approx $400-$600)

if you find a dana 44 that doesnt have the right gear set your gonna be out the same money to change gear ratios plus the cost of hte axle.

the only really bad things about the AMC20 is are the 2 pc axles ( a kit can fix this) and the weak housing/tubes ( which can be fixed by welding)

it just depends on what extent its damaged and what he wants to spend.

the cheapest and easiest thing would be to find another stock Jeep axle, with the same gear ratio and use it until it breaks.

Re: Replacement for AMC 20 rear axle

Not sure what the gear ratio is offhand. I will have to go over and figure that out. He bought it just a little while ago as his first Jeep.

Re: Replacement for AMC 20 rear axle

The Scout axle, even though it has the same bolt pattern, is about 8 inches wider. It isn't a bad swap if you do the front also. It might look a little strange with a widder rear track. My suggestion would be a Wagoneer front, it is a easier swap than a Scout front, more caster, to go with a Scout rear. If you go trough all that trouble, you might as well go full width 3/4 or 1 ton hardeware. It wouldn't cost much more, and you get wider axlez ( more stable ) and a stronger rear end, stronger front if you go 1 ton. One more option would be a 9 inch Ford out of a early Bronco, same bolt pattern, but still to wide if you don't swap the front. I still havn't made up my mind, but I am leaning towards a 1/2 ton Ford 9 or 8.8 inch rear, and a GM D44 front, converted to my CJ brakes and hubs.

Thanks, Ray

Re: Replacement for AMC 20 rear axle

Turns out a guy in Spokane had an almost new Dana 44, solid axles limited-slip that he was willing to part with. After dealing with spring plates without shock studs and holes in the spring perches being to small it is in and working awesome...
