I just picked up an 81 SJ and was a little disappointed to find it had the AMC 20 rearend and not the Dana 44. Exactly how much weaker are they and where?
I've heard that it's the axle housing and tubes that are the weak point, and not the carrier assembly or the axel shafts. The last dana 44 I had was spooled and I never had any problems at all with it, and I'd like to do the same to this axle. Besides the obvious, would there be any problems spooling an AMC 20? No big tires or anything either, just some 30x9.5's or so.
