On the downside, and I'm hoping maybe jnaut and tranceformer will chime in, I talked to the shop that put em in today. Told him about the whine under light acceleration, just enough drive input to maintain speed, and he acted like there was nothing more he could do - he said the mesh pattern was perfect, and then gave me the dreaded "some gear sets just whine ... can't tune em out"
Told me to drive it for awhile and let everything "seat" and see if it changes any. I'm also going to switch to Redline 75W90 to see if it helps any. But I don't think it will. Any reason to believe that this may work itself out after break in ???? That just doesn't make sense to me ....
So I'm hoping you guys can give me some ammo to go back with ... as far as specific adjustments. Anyone else see this? Any experience with pinion preload adjustments? Mesh patterns that work better than others i.e. more toe, or more heel patterns? Anything that will convince him to break into it again and make an adjustment.

I found this thread (and forum) via a search trying to find if the pinion sleeve and nut came with the gear set.
I have had these and a quaife in my 06 350Z for over a year/10k and just started whining horribly. It started as you described.
My differential was assembled by a shop that had no clue and is now out of business. They did not replace anything but the ring and pinion and apparently did not properly set the preload. It is currently at a shop that only deals in diffs, transfer cases and transmissions.
As I did not want to lose my car I swapped the open base diff back in. WHAT A DIFFERENCE.
Luckily it looks like there was no damage.
