Looking to tap into the brain trust for some insight into my 489 case 8-3/4"

I have about 2,000 miles on this set of gears, which I purchased from Dr. Diff and set up myself. I have a noticeable gear whine at most any speed, more noticeable on decel. During my quarantine time I've decided to pull the 3rd member and see if there's anything that can do to address the issue while it is out.

Specs as follows:
New pinion and carrier bearings
Crush sleeve eliminator, set to "new" bearing turning torque w/beam in-lb torque wrench
New Motive 3.73s, measured 0.007" backlash [Spec 0.006"-0.010"]
Rebuilt SureGrip


Looking at my Yukon guide, my pattern seems to best match the top-left one shown under "acceptable patterns". At this point, I am not seeing anything that needs adjustment, but I know the gears are noisy.
