Default blown locker-advice needed

Well, the rock course in St. Helen claimed a few parts on my rig this last weekend, one of which is the rear locker. I had an Auburn ECTED in the rear for 3 years now. Been a pretty good locker, but I was surprised to see it go this early. Since it's less than 4yrs old, auburn will cover it under a program they have and send me a new one for $265 shipped to my door. However, I've not had problem one with my loc-rite in the front axle during the 4 years I've blown a detroit ez and this ected. Should I say screw the electronic ected and just opt for the loc-rite? It's in an '86 cj7, amc 20 rear with chromoly one piece shafts. 5.0HO motor. 35" MT'S. Thanks for the advice. And yeah, tons with a real detroit would be great, but unless you have this setup for less than a G don't bother mentioning it

Actually considering that! I don't see much pavement with this rig anymore. Have a second jeep we're building up for that. Second question, regardless of outcome with locker, it's gonna need to be set up, shimmed, etc. I've never done that but I've done nearly everything else. Motor swaps, trans, etc, etc. Just never set up an axle. Should I remove the axle and take it in to a shop or is this a doable task for a shadetree mechanic? I've got a couple more axles in the other rig I'd like to eventually change gears in so if I'm gonna learn it eventually, might as well be now. What's your opinion?

You didn't mention tire size. 36" or less I would consider a spool. Bigger than that and I'd go lock-rite.

I had a spool in my TJ and liked it. Super reliable. Very predictable handling. Cheap.

Then again, I don't know much about the AMC 20, but if you have broke twice, could it be the axle is just undersized for what you are doing? You could put in whatever you want, but it'll likely break again. Rear 60s can be picked up cheap. Spools for it are cheap. And you could probably run stock shafts in it to without issue. It would likely be too wide though and if you cut it down, then you're looking at different shafts. Just thinking out loud.

Edit: What about even an 8.8 swap? That's what I had in the TJ and never had issues. I've seen guys beat the shit out of them too without issue. For the tire size you're running, that would possibly be a cheap upgrade. Again, I don't really know how strong the 20 is though. I'm only assuming it's somewhat weak.

Spool. There is a ton of info on gear setup on the interwebz, learn how and don't look back. Get in touch with Bo'sCJ7 on here he is from Rose City I'm sure one of his bunch can show you how it's done for some .

Yes, for that size tire, spool it or weld it.
