Re: [Amc-list] Rear End Swap

The only difference I can think or maybe spring isolators?
I can't remember what years used those.
That being said, if you use all the pieces from the 73 it will fit the 72.
You may, of course need to swap rusty or wear and tear items.
The other things to watch for are an AMC 15 or AMC 20 difference and gear ratio changes.
All of that can be overcome if needed.

If they are matching AMC-15s or 20s you will likely be able to repair his existing reardend by swapping and axle and hub from the parts car into his. That sound you describe is usually a spun hub on an a rear axle. Do not try and take a hub from the replacement axle and put it on his though! Keep the hubs matched to the axles!  New hubs are unsplined and the hardened axle cuts the splines in the hub on the initial install. swapping them after that ensures they will strip out.

On the replacements. You want to loosen and lightly lube and clean the threads, then retorque to 250 ftlbs.  Failure to retorque after all these years is the most common cause of failure.

Last if you move axles from housing to housing you should check preload. Refer to TSM for those specs. I am lost at that point !

Whew, I'm done now!
Hope I got it all correct and understandable!

Subject: [Amc-list] Rear End Swap

A fellow club member has a 72 Hornet 2DR whose rear end makes one heck of a  
noise and an axle appears to be frozen in place. There is a 73 Hornet  
Sportabout available at the local Pick and Pull. Can someone tell me if the  
Sportabout rear end would fit, without adjustments, into the 72 Hornet ???   
Appreciate any and all help is appreciated.
