Power Train Driveline problems of the 2005 GMC Sierra 1500

Multiple reports to the dealership of a continuous vibration and noise in the front end accompanied by uneven tire wear. Tires were rotated reducing but not eliminating the noise. Three to four hundred dollars was requested from me by the dealership to remove and disassemble front differential for further investigation. This request was denied by me because the vehicle was still under warranty. Within 1100 miles and two weeks of last inspection by dealership, front drivers side wheel bearing catastrophically failed. During this event the vehicle became nearly uncontrollable and dove into the oncoming lane, steering was violently reactive and the vehicle ended up traveling off the road into the ditch in the of the direction of travel. The brake rotor and caliper had become red hot setting fire to the drive axel boot and grass beneath the vehicle. The fire was able to be quickly extinguished. Death and/or injury were only avoided due to the lack of traffic in the oncoming lane and no obstructions in the area of the ditch within which the vehicle traveled. Results of bearing failure include destroyed brake rotor, caliper and pads. The front drive axel was purged of grease through extreme heating and axel boot was also destroyed. Although repairs have been completed by the dealership I have incurred a 300 dollar towing bill which the dealership, general motors, and the warranty company gmpp are refusing to cover. The dealership is claiming that there is no diagnostic method of inspection to predict eminent wheel bearing failure. The manufacturer is refusing to acknowledge the multiple reports of the issue and supports it's dealerships practices. The warranty company is only accepting liability of 50 dollars for towing which I have had to pay 300 dollars for.
