installed 4.08 final drive and the car is AWAKE, it is a blast to drive hard now... Its a pretty darn good mod as far as increase in speed and performance go.

But I have a pretty obvious whine from my diff now... I thought this should of been very minimum with the OEM 4.08 final drive. Its pretty loud at 80 and very noticable even crusing as soon as it gets to about 3k RPM... Is this normal ?
