Help, Gear Whine...After New Setup

Launching!
High up on the heal of the tooth is an acceptable pattern. I personally like to keep it as centered within the tooth as possible (moving pinion closer to centerline of ring gear in your case will move pattern toward toe) and always recheck backlash and then pattern again to make sure they are in spec under load. It’s nearly impossible to get an absolute perfect pattern

Just curious what was your OEM pinion shim thickness?
Not that this will will help because all setups are different...
My OEM pinion shim was .033 and using the crush sleeve eliminator kit my final pinion shim was at .034 with a 18 in/lb pinion preload. My final backlash was .008 and with holding resistance on the ring during the pattern this was my final pattern.

Try another shin to bring closer to toe, but pattern is starting to look more defined which is good.... just remembered I never asked what rear ended is this? Do you have the removable pinion, six bolts hold it to diff housing? If so then yes add shins if not the you have to remove shims from the pinion.

I'm not real good at interpreting patterns, but...
Your description of the sound, sounds to me like either your left carrier bearing is farkled, or the carrier has end play.
How much preload did you put on those, and how did you accomplish it? It's not impossible that you have so little carrier brg preload that the carrier has play from side to side. Should be as much on them as you can realistically put without destroying something; usually .010" or so.

Finally got it all sorted out ran test patterns with a .034 and a .019
Final setup was a .022 pinion shim I honed down from .029. Kit I had jumped from .019 to the .029
Backlash settled at .09
Thank everyone for helping me out, running quiet now.
