| Description of the problem | 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. |
