Thanks to Roger...aka...forum member 1970390amx; I now have a complete AMC 20 twin grip rear end with a 3:54 gear set ready to install in Project Gremlin X. I walked into his shop this morning with a couple of camera's & no knowledge. I walked out with a wealth of information & his permission to share what I learned today. I've put together a DVD for those who are interested in learning how to set up an AMC 20 rear differential. It's one hour long, has chapter markers, and covers the following topics... 

-Teardown & inspection
-Pulling the hubs
-Pinion Bearing Race R&R
-Roger had a 3:54 ring & pinion set waiting for me without the pinion bearing so he pressed on the new bearing & mocked up the pinion gear for a wear pattern
-Carrier Bearings R&R and Ring Gear Removal
-Shimming the Carrier
-Using a dial indicator to confirm that the carrier spins true before mounting the new ring gear to the carrier
-Shimming for Proper Gear Backlash
-Checking for the Proper Pinion/Ring Wear Pattern
-Installing Pinion Spacer (replacing the crush sleeve with solid spacer & shims)
-Checking Pinion Rotational Torque
-Final Setup
-Axle & Seal Installation
-End Play Shims & Hub Installation

If anyone is interested in purchasing one the cost is $10.00 + shipping and 50% of the proceeds will be donated to this forum. You can order one by sending me a PM.

Dean

All the videos are now up on my gallery page with a link to each one in streaming Quicktime. This is kind of an experiment in sharing information so feedback is encouraged...

I enjoyed watching this series showing the re-build. It's not something I could do myself, I wish I could because the rear in my car is going to have to be re-built due to some whine, but it's good to see how it's done and what's involved. Two questions...knowing the inherent weakness of the AMC 20 with the two-piece axles, why not install one-piece axles at this point and is the soundtrack to this video series available in the lobby? Smile Some good tunes there.

Glad you enjoyed the series & the answer to your first question is that (IMO) the stock axles will hold up for my application given the car loaded, will be under 3000 lbs & running non sticky street tires (for now). In the event I decide to run some drag radials some day & take to the track on a regular basis; the one currently in the Gremlin would be a good donor & I think I know someone who could weld up the tubes & install the one piece axles. Wink Maybe a project for another time, but for now I'm trying to stretch my dollars for some other goodies on the car. 

The video series along with the soundtrack (lobby) is available on a DVD I put together last week to free up some space on my gallery page. I have edited my original post & updated it with details.

I just wanted to let anyone that has thought about rebuilding an AMC 20 know that this is a great video, well worth the $10 + shipping. I have always had the tools and the willingness to set up  rearend but I have always been reluctant to do one because of the uncertainty about how all of the measurements were done. This video (about 1 hour long) covers all details of tearing down, taking pinion, carrier and axle measurements and rebuilding an AMC model 20 rearend. My advice if you want to try this is to buy the video and see how it's done.

Anyone interested in a copy can send a $10.00 donation to the forum then send me a PM with shipping info & I'll get one in the mail. I currently have 4 copies left but should be able to burn some more if needed.

Thanks,
Dean
