kdexter89 Posted December 23, 2015 Share Posted December 23, 2015 I have been doing a lot of research on the AMC axle in the MJ and it's variants. The thing is I can't find if I should call it an M-20 or M-23. Could an axle guru give a guy a hand! Maybe provide some documentation on how to spot the difference in the two.

88whitemanche Posted December 23, 2015 Share Posted December 23, 2015 It is called the amc 20... It was also used in cjs, full size Cherokees, and j-series trucks Here's a thread that gives a good amount of info... http://comancheclub.com/topic/45147-amc-20/?fromsearch=1 Link to comment Share on other sites More sharing options...
cruiser54 Posted December 23, 2015 Share Posted December 23, 2015 AMC 20, Corporate 20, Link to comment Share on other sites More sharing options...
HOrnbrod Posted December 23, 2015 Share Posted December 23, 2015 The AMC M23 is the FSJ version of the M20 used in AMC cars, CJ's, etc. It is stronger and does not have the 2-peice shafts like the M20. They have flanged shafts and are 6 lug. Link to comment Share on other sites More sharing options...
