Locking rear axle

The other thing is Bill already made his decision. I think he made a good decision to install a locker in his AMC20 . He is addressing the axle shaft issue with one piece axles. He's getting the tubes welded. He's going to have a damn good axle when he's done. Now is not the time to tell him to get a Dana 44 . Now is not the time to go over the other options. He made the same decision I would have made. Actually I was faced with the same issue and kept the AMC20 and improved it like Bill is doing. Back in Minnesota I had a '84 CJ7 and I put in an ARB air locker. I never had any issues with it. Now I have a '79 CJ5 with an OX locker in the AMC20 . It's been running good too although I have had to readjust the linkage once because the cable became too loose to lock the diff.
If you make these improvements the AMC20 is a good axle.
The great thing about a selectable locker such as the ARB is you can turn it off for tight turns. Also turn it off on slick roads.
Also, my front Elocker is a simple matter of flipping a switch on the dash to disengage it. No backing up, no banging, just engaged one second, disengaged the next.
