Also have Quafie, no whine on mine.

Seeing how the Quaife differential is a Torsen type (gear driven) differential it should not make noise and is one of the quiet aftermarket differentials you could possibly choice. Something obviously is not right when exactly is your Quaife differential making noise? What differential fluid are you using? Engagement with this differential is not harsh and technically requires no break in period.

The unit it's self makes no noises unless it's broke. The whine is from the ring and pinion. Either too tight or too loosen. Have to check backlash and toe pattern.

Not properly setting pinion depth will contribute to noise aside from a improper backlash setting.

That's where you do a pattern check. That will show you where the pinion is sitting at on the ring gear.

I've done my share of doing gear sets.

I’ve been installing all my ring and pinion/differentials enough to know Captain Picard palmface your our self.

Clearly the OP installation was screwed up. If the OP can not correct this himself then he should have a shop fix this for him.
