New true-trac differential whine

To prevent the argument, the pinion angle is incorrect. How's that?
Not good enough imo......you act like the 'man in the know' but can't seem to tell me anything I don't already know. Saying that cruise is the same as coast is what I gathered and to me, it's not the same. If you can't say to adjust the pinion in deeper or out more then why say anything?
