There is nothing wrong with full floaters on an AMC 20. Some people will poo-poo them because they
don't want to spend the money. The biggest advantage to full floaters is that the axle doesn't have to
carry the weight. I've had a set of full floaters for about seven years, a friend of mine put them on his a
few months later. He is one of the hardest core rock crawlers that I know of. Worst thing happened
was he exploded a rear lock-out and pulled two studs out of the hub and had to have them redrilled
and tapped. I don't think he can go crawling without exploding at least one hub, I think he buys by the
case. Here he is out doing his thing with the full floaters.
Both of our kits were Summers Bros. and have held up well. I don't know about the Warn kit, but the
Summers Bros. uses the same bearings and seals as the front stock hubs on my '80. Don't let
somebody who doesn't want to spend the money tell you that one piece are just as good and don't let
somebody who doesn't understand physics try to tell you that floaters put more strain on the axle tubes.
Look at the big heavy trucks, what do you see? Full Floaters. Yes they are more expensive and yes
after about four years you need to replace the inner axle seal (which is a pretty trivial chore) but you get
much better bearings and no load on the axles.
