Ok here is my delemia, I apparently broke a axle on my m920 driving it up the driveway last weds( driveway is 18% grade with 180 degree wrap) I had aproched in to high a gear and got the truck in a hop. I didn't relize it til today when I needed to move it that the drivers rear wheel was free wheeling and not driving. I removed the paint off of the axle tag info to see if I could get a axle locally and or quickly . But it has been sand blasted to the point that this is all I can make out. There looks like there could have been more info on the tag. But it looks worn off.

I wonder if the axle shafts for other, earlier 800-series 5 tons would fit. Any chance you have a length and spline count? If you are worried about gear oil spilling out, you could jack or drive that one tire up on a block, hopefully raising the bottom of the spindle above the fill hole on the pumpkin.

M920 is much too different from a M839 series 5 ton. Maybe you are thinking OP has the M939 series instead?

This is what I got for the driver's side rear rear axle shaft -
3202-Z-7384
Each axle shaft in the truck has a different part number, apparently.
There even appears to be one on ebay right now...

The M920 20 ton has much larger axle shafts than the M809 5 ton.
Unfortunately the TM gives a general # and does not give the axle info ( Spline , Dia, Length according to the local rockwell dealer) So I'm back to square 1. The numbers I gave them off of the axle that he asked for came up obsolete.
Got it installed and with the help of AMGeneral it is now working flawlessly.
Thanks again for the assist.
I owe ya one.
I'm so glad that worked out for you Richard !! I couldnt imagine climbing up under the hood everytime I would have to turn my truck off and on .
I was able to order that Axle off of e bay and hopefully will be back up and running soon ! I also broke a spring strap . but thats a easy fix. hopefully nothing else was harmed. When it happened I was a bit to hard on the throttle as to keep me from rolling back down the hill. The sad part was I knew better, but the truck was at cat so long I was giddy . and with the trans working flawlessly I was feeling my oats and left it in 7th instead of 4th like I normally use. I told several people I had swore the axle broke . But couldn't prove it until today when it was a limp noodle.
Thank you ! Thank you ! Thank you !! You are a life saver !!!!
Double check that I read everything right. I am not actively trying to deceive you, but I may have read it wrong. That number came out of the -24P manual.
I don't want you to purchase that axle then have it be the wrong thing and blame me!
