As posted previously the 2 driver side wheel bearings were replaced at a cost of $1500 but they also had to replace the differntial. This was at a cost of 2000.00 to me for a total cost of 3500.00 for the overall service. Extremely dangerous to drive the vehicle and was lucky the wheel or something else did not cause an accident. Again Infiniti brushed off the issue even though they sell this vehicle which is presumably one of their upper quality luxury vehicles. Well done Infiniti! Good luck in me ever buying another one.
