Differential Unit problems of the 2006 Nissan Titan - part 2

Incident occurred during normal use of a 2004 Nissan Titan. No suspension or drive line modifications. The differential failed when turning right onto a busy street. There was a loud bang then a grinding sound. The truck would not drive after that. Every time I tried to accelerate the truck would just grind and not move. The truck was taken to royal moore auto center in hillsboro, or. Where it was purchased. The service technician looked at the truck the next day and said the differential needed to be replaced. When he made the order he said Nissan would not give him a delivery date for the part because it was back ordered. It's been a week and I still do not have an estimated date for part delivery or repair.

Rear end vibration started immediately after purchase. Rear end had to be replaced at 3,500 miles.

Ok picked up truck from dealer and it started humming 3 days later. No one at dealer would believe it went bad that fast. Had to drive it 2000 mi and bring it in when the hum was very bad for them to believe it.

Well for replacement number two. Started humming took it in and differential was full of metal shavings.

The vdc [vehicle dynamic control] kept shutting off. This is a safety feature to regulate motion and speed of the 4 wheels. The vdc would not turn back on with the vdc dash button. The dealer stated the rear differential bearings had failed and the Titan was unsafe to drive. It's been at the dealer waiting for a new rear differential for 2 weeks. The truck was not delivered with the power folding - auto dim exterior mirrors; the xm radios did not work; bed extender not installed; gas tank wasn't full as promised.

Rearend started humming at 2500 miles. Took it in and had checked fluid looked like gray metallic paint and was low. Technician said that was normal. Took back week later and demanded fluid be at least changed when fluid was drained service manager decided to replace due to excessive metal in fluid.
