A compare contrast photo. Has some gear whine and pinion pre-load is tight, although I'm going to run it 500mi. and re-do it. It is the 8.25" rear with 4 56: gear set, wanted to show.
Nice! Doing that under the Jeep must be a PITA

Drive side is way too high, once you punch it, the contact patch is gonna be half off the teeth.
Adjust pinion depth

My complements to you as well. Two air actuated lockers is impressive. DIY work isn't new to me as I've owned it since 2003. The gear set is new. It is exactly the same 4 56: as was previously installed, minus a True Trac carrier. The pinion depth remains the same and without a shim. The only reason for a lack of depth toward the front would be rear bearing cup not fully seated in the diffs housing bore.
Possibly moving RGS more toward the NRGS would improve the contact pattern.

Assuming this is a HPd30, drive side is too high.Alright it's time for the front D30/ARB. Any input on this pattern? Specs are IP 0.054", RGS 0.020", NRGS 0.062", 0.007-0.008" backlash, and roughly 0.005" carrier preload per side.

we flush with mineral spirits and scrub out center section and tubes. blow them out with compressed air and still have some small amounts of metal.

This socket was used to adjust front locking hubs, can be used on your carrier bearings L/R 8.25" also. Can find it and the 1/2" extensions at an auto parts store.

And old hub nut welded to a long piece of pipe with a nut welded on the other end is simple to fab.
