I have welded my front D44 and am considering doing the same to my AMC 20. But two things hold me back.

One. I am worried it will eat the crap out of my rear tires during daily driving.

And two. I am wondering how the rear axle shafts would hold up.

I have a Wagoneer with a hot 401. Around 380 HP and 450 FT-LBS.

I am running 31"MT's and 3.31 gears.

What kind of trails do you ride? I did a lot of stuff in a 4" lift waggy wit 3.31 gears and 31" tires. Great combo. I started with a ARB in the back and tossed an aussie up front. The few times I had ARB problems (electical/air) the Aussie up front did the job! But that was on 'easier' trails.

Basically it is a cost thing. Welding is free. The tires will wear down faster. A locker will cost more. So ask yourself 'How much driving do I do' and what kind of wheel'n do I do as well as 'will I want to upgrade axles later?'. Don't toss a bunch of money in an AMC if you think you want to do D60/14 bolt. I made that 'mistake'.

I would be hitting some mid level trails in Gilmer TX's Barnwell park.
Occasionally power line roads.
And I will drive it about 40 miles a day round trip to work. Mostly country roads and highways.

Since you put it that way I might weld it, wait until it breaks, then replace it with a GM or D60

Good luck, either way. Wouldn't want that weld to break on a highway to work, though. I think the detroit lockers can be had for under $600.

I really don't like BJ's too much. I never had luck with ordering from them.

After 6 weeks of waiting for an Aluminum radiator, a Mallory hei, and other items totaling $1,000 I cancelled it because they couldn't tell me when they would get some of the parts to complete it.

I found an Aussie locker for around $300.

Thanks. I have actually began my first full blown rebuild of an FSJ (how I ended up here), but have had good luck with Detroit in my past 4wd's. That is good to know about BJ's, by the way.

Well like he was saying, I'd hate to put a Detroit in the AMC 20 then swap it out. If I can find a D44 from another FSJ to replace it I would consider the Detroit because I could use it in the front too.

I installed the aussie in my front d44. Since you don't change carriers I didn't have to mess with the gear alignment. I believe it is the same with an amc20. So for a few hundred bucks and some wrenching you might be able to have a locker that would fit your needs but you wouldn't be tossing a lot of money away.

I put an Aussie mechanical locker in my AMC 20 and it does great, i have a MCX 350 pushing close to 350 hp and never had any problems. I have close to 11,000 miles on it now.

I had a spool in the 9" on my 63 galaxie convertible. Was awful on the street and destroyed tires. Complete misery in parking garages. Installed a Yukon posi works great.
