8 3/4” carrier bearing preload

I read that also about not really being able to have to much preload. I will probably just stay with using torque value. Just first time I read about using case stretch. Thanks.
Only time I have used a case stretcher is on Spicer type rears like Dana 44,60,70 and GM 10 and 12 bolt rears. Never seen one for a third member.
