Here is one of the articles I found on setting up the differential that references the carrier bearing preload.

I would have gone higher if the tool I was using didn't keep slipping out of the adjustment notches.
I'm in the process of doing a gear swap soon ( 4. 57 ) and i would like to know if you have a pic of this tool ?
Thanks

If you set the carrier bearing to 50-100 ft-lbs, I promise you it will self destruct. The 90-200 ft-lbs on the pinion is acting on the distance collar. The actual load on the pinion bearing is only a few ft-lbs. I've done about 20 gear installs, including a few on the S2000.

As far as torques are concerned, be careful that you don't make direct correlations between torque values and axial forces generated by the threaded fastener.
The carrier assembly and the pinion stack are very different in that the pinion uses a pretty standard diameter, pitch where as the carrier uses a large diameter thread that look pretty fine. I'm not sure what the net effect is but I'll bet a lunch that the same torque value generates a vastly different clamping force.
As for the whining gears, get the backlash right and it will be quieter than when it's too tight. Too loose is still quietish but hard on things due to the excessive play allowing teeth to hammer on each other. Either way though, the carrier needs to be preloaded or it's going to be noisy and potentially rough. For those w/ loud gears that run smooth you might try an extra couple thou backlash. For those running rough (vibration) make sure the carrier assembly is properly preloaded.
BTW, I'm not running these gears
