Grand Cherokee 4WD 8-cyl

Whining noise coming from back of 2006 Jeep Grand Cherokee; removed drive shaft between transfer case and rear diff-found U joints on each end slightly tight; had new U joints installed (had replaced by a custom shop as Jeep driveshafts and U joints are one component and cost in the $1200 range to replace)-my U joints are now serviceable and can be changed at any shop; problem still existed after repair, removed transfer case-no problems there; opened up rear diff and found pinion bearing pre-tension had been overtightened (my mechanic says this was done at the factory as this case has never been opened up prior to this)-gears were still okay but bearings showed signs of stress so changed out all bearings in diff and re-set pinion tension; problem now solved-my out of pocket cost - $1300. This vehicle has 53000 miles on it.
