REGEAR ASSISTANCE PLEASE!!!!

so otnoc and i spent all day regearing his front 30 with superior 5.13s and we ran into a problem...we cant get the pattern right and were binding in one spot...were using all new bearings and races, stock pinion shim plus .015, stock carrier shims, backlash is at .0085...we torqued the ring gear properly but now im thinking the ring gear isnt set correctly cause its binding in just one spot...pinion is set to 30 in/lbs turning
here are some pics of the pattern we have with with the stock shim plus .015...we have the tiniest bit of binding in one spot...no binding with .010 but need to move the pattern...we were at it for 12 hours and started second guessing every move we made so some more expert help would be appreciated

Less shim. Go thinner then factory.

Not sure about a general rule.

My front stayed the same and the rear I had to start from 0. I think I ended up with .012.

Just went thru this last weekend. Hours and hours of second guessing the shims, only to go back to stock on the carrier shims, and close to stock on the pinion shim. When we originally tried the stock shims only, the pattern wasn't right, but when we went back to it magically things fell into place. Same thing might have happened to you.

If that doesn't work, the pattern says you need to adjust the pinion shim. That pattern should be more toward the middle of the gear, not out on the edges. We had the exact same symptom when setting up the rear as well, took out .003 when the pattern looked close, but it was binding and everything was perfect thereafter.

On these dozens of JKs I've done, adding .002 to the rear D44 pinion shim, keeping the stock carrier shims makes a perfect pattern ONLY if it's a 0 gear.

On the front, keeping the stock pinion shim and adding .003 to the driver's side of the carrier makes it tighter (ALL JKs I've done the D30 carrier/ring LITERALLY falls right out once bearing caps are removed) and makes a perfect pattern. ONLY if it's a 0 gear.

This is using Yukon's gear sets and have yet to see a variation, +/- .001. I keep my backlash a little tighter, .005-.006.

Your pinion shim is WAY big.

Make sure your B/S is close, snap a pic and post it back here.
FWIW I had rear gear from the same company with a tight spot.

ok cool...i was thinking the ring was off...but couldnt get .001 feeler in anywhere around the rim...were gonna get back on it wed morning... got new bearings coming...dont remember the stock pinion shim size but when we ran the pattern with all stock it was off, no binding either...it was my fault ultimately for this shit cause i was reading the coast side for adjustment and all but disregarding the drive side... dumbass
