I had a guy want a pair of axles from a V8 Rambler American (AMC20). He needed them for a SC/Rambler. I told him that the hubs would have to be pulled, new bearings pressed on and then the axle nuts need to be torqued to at least 250#/ft. long story short, I told him that I would just do it for him because I actually have the tools. My hub puller from Hell. I restored a BBO AMX for a guy sometime in the 80's and he happened to be a machinist so he made this one for me out of stainless.

It is the center of a Jeep Comanche wheel with a 4' chunk of 3/8" x 1 1/2" stock welded to it for a handle.

Luckily I was there to catch it! IMG_0775 by Rick Jones, on Flickr The Axle Coffin IMG_0783 by Rick Jones, on Flickr Weighs 72 lbs. IMG_0785 by Rick Jones, on Flickr

Nice set of tools there. IIRC, the torque spec on that hub nut is 450lb-ft.

Nice work Rick. And that hub puller is pure badass.

Isn't that how Kent Moore started making special tools? Looks like there's a new line of special tools for AMC's.... "Rick Jones Tools"

That hub puller made quick work even on a spun/friction welded hub on my original AMX axle!

I torqued these to 250#/ft. then, torqued them higher so that the castle nut lined up with the cotter pin hole. They ended up at over 300#/ft each. IMG_0804 by Rick Jones, on Flickr

That hub puller made quick work even on a spun/friction welded hub on my original AMX axle! Yea it worked even better once we remembered to actually take the axle nut off. It was struggling a little before that.

I bought a case spreader made for dana axles. Then i modified it to fit model 20’s. You pretty much have to have one to get “shim packs” into place at the carrier bearings. Factory axles came with spacers. New ring and pinion setup kits come with various thickness shims that you have to juggle. Lots of time spent measuring with a micrometer and juggling shims to get the magic backlash/ bearing preload numbers. The other thing that sux ass is getting the right shim between the pinion bearing cup and the case. I sometimes have to do that a half a dozen times before i get a good pattern. The shims are in the way when you want to drive the cup out and unless you plan ahead and cut notches in them, you destroy them banging the cup out. I dont like working on these fucking things at all!
