Geonovast Posted September 20, 2007 Share Posted September 20, 2007 I have a possiblity of picking up an AMC 20 rear end for fairly cheap. Does anyone know anything about this axle? If it's good, would I be able to use it on my MJ? Link to comment Share on other sites More sharing options...
DirtyComanche Posted September 20, 2007 Share Posted September 20, 2007 What's it out of? CJ ones are crap. Unless toy want to change the axleshafts right away. The MJ/SJ ones are decent. The ring/pinion is strong. The stock carrier is alright. The stock axleshafts are pretty good too (D44 sized). But the axle tubes are weak and need to be trussed for hard use. At least weld them to the housing (like on an 8.8 ). There's a decent aftermarket for them too. Link to comment Share on other sites More sharing options...
Geonovast Posted September 20, 2007 Author Share Posted September 20, 2007 I have no idea what it's out of yet, but I can find out. I really wish I'd scrapped my J10 instead of having to have it hauled, it had (probably) a D44 front and either a D44 rear or a D60 rear. Oh well :( Link to comment Share on other sites More sharing options...
comanchedude Posted September 20, 2007 Share Posted September 20, 2007 Find out what it out of, if its from Comanche its a great axel and the tubes don't bend easy like some would like you to think ,all the trash talk is based on the old CJ axels. :roll: The AMC 20 that came in the Comanche is a much stonger unit with the heavy tubes ect... If its out of a FSJ it will be the same HD unit that the Comanche used but the width will be diffrent. The only "real" drawback is you don't have an easy cheap source for aftermarket axel shafts like the more popular units..but you can get stock units from the salvage yard. and unless your running tires larger than 35" and locked you will most likely never break one Link to comment Share on other sites More sharing options...
Geonovast Posted September 21, 2007 Author Share Posted September 21, 2007 Well my intentions are to eventually be running 30s, and when whatever rear end I get gets locked, I'll be paying the money for an air locker. I e-mailed the guy that has it, but he still hasn't responded. Link to comment Share on other sites More sharing options...
Oizarod115 Posted September 21, 2007 Share Posted September 21, 2007 like he said, CJ=2-piece axelshafts=crap. MJ/XJ would be a good axle, a little harder to find parts for but not bad. and yeah, the J trucks had nice axles... 6lug though and wayyy wide Link to comment Share on other sites More sharing options...
