I’m swapping ring gear and pinion because the pinion in the rear end has chipped teeth. It looks like I will be learning about how to install and adjust the set and backlash. What can I use for the tool to tighten the differential bearing nuts? I should mention that this is a torque tube rear end.

If you go to the site it gives size so you can make one ,somewhere there is a pattern you can print and trace to make one .

I used a screwdriver and a hammer to tighten the nuts. So far so good. I took a test drive and it seems good, maybe a little backlash but no worse than other old rear ends.

That or a hammer and a blunt punch will do it just fine. Good luck.

90 degree long nose pliers work ᠁᠁᠁the points go into the holes on the “nuts”.

The device in the DEVE post is the pinion bearing spacer tool.p
The factory tool is pictured below.

Pin-type spanner wrenches are all over Ebay, both fixed span and adjustable types. The thin open end wrench in the picture is used to adjust preload on the pinion bearing, not the carrier bearings on both sides of the ring gear. I learned to adjust the ring gear backlash by moving the carrier assembly back and forth and checking backlash with a dial indicator, and then tightening both adjusting nuts one notch to preload the bearings. It's worked well for me that way since the mid-1960's.
