Olds77421

About 6 months ago I purchased a full floating 1 ton 2WD axle to swap into my 76 Chinook. Today, I finally got around to tearing it down only to find that the previous owner galled the threads on the axle housing. I was able to get the retaining nut off (it was a total PITA!) without screwing up the threads any worse than they already were, but need to chase the threads on the axle housing before I can rebuild it. Does anyone know what size / pitch the threads are for this? I've looked online and cant really find any info. Thanks!

Thanks this is incredibly helpful. Should be fine in terms of fabrication to make the new axle work. I'll make sure to post an update on the process for posterity. Also, If I'm reading that all correctly, I think I can use my center section and just swap over the ring and pinion (if they're in good shape) from the old to the new to make everything work. Now I just need to track down some new bearings and seals for everything!

Thanks for the info, all. It's definitely helpful. I plan on keeping the 4.30's in there, since the vehicle also has a W55 trans with OD. I'm looking more for the step-by-step process and specs for the rebuild. Mainly, backlash, pinion nut torque, etc. Resources for the semi-floating rear ends are plentiful but below are the only two links I've been able to find and I can't verify the specs (or find PNs for anything.) https://www.yotatech.com/forums/f120/need-info-repack-bearings-do-brakes-1-ton-full-floating-rear-axle-wheels-268282/ https://www.differentials.com/technical-help-2/set-up-specs/ A FSM would be SUPER helpful if anyone has a line on one.

I was able to score a 1 ton 8" axle out of an old Dolphin from Facebook marketplace and plan to swap my G082 diff for the full floater. I'd like to rebuild it before installing it, but I can't really find any resources on specs. While I'd imagine the center section is basically the same, does anyone know if there are any resources for rebuild procedures, torque specs, etc. for the 1 ton?
