OP, don't you also want to measure backlash before teardown? I've watched a few of those teardown and rebuild videos and it's a bit tricky to do it. Unlike a solid axle differential, the ring gear is not exposed after the case is put back together.

Or, I'm assuming you are going to install new ring & pinion gears? Maybe not the case? What gears do you have?

I'll have to read up on the backlash. Thanks for that tidbit. Going to keep the gears but will replace the bearings on the differential case and also pinion shaft.

Watch this video. This guy works on Duramax trucks, but they use the same IFS as the GMT 400 8 lug trucks:

Excellent video. Still watching it (at 17:24 so far). I noticed that he didn't remove the rubber case bushings yet. I wonder if he will get to them before the video is over.

...I skipped thru it. Did he mention anything backlash? If not, must have been elsewhere so saw that.

I like that channel. Very good infomation an no BS drama or heavy metal background music overpowering what dude is saying...

I think that keeping the shims and new bearings and races your backlash should be okay. Same for wear pattern. Only have to worry about preload.

I don't see that he measured anything before disassembly. And he never actually used a dial torque wrench to measure torque to turn. He's old school basically. I wouldn't trust him to do my own differential, but I still learned things watching the video. Good stuff.

Didn't watch the vid, but I can say the side bearings don't use shims just like the bearing caps in the heavier rears. And yes, you can set bearing preload by feel.

Got it stripped down to firewall. Lot of cleaning, refurb, and repair ahead --- and yeah, planning on a replacement dash eventually.

Great foundation.
