My 2003 GMC Yukon denali had just over 63,000 miles on the odometer. I am the original owner of the vehicle. The majority of the driving has been on paved roads/highways. The hub assemblies (both sides) began making a noise in March of 2006. Since the vehicle was out of warranty, I took it to a local certified auto repair facility and had them look at it. They told me that both front wheel hub assemblies were in immediate need of replacement and that there was a danger in driving the vehicle. I had the work done on March 22, 2006. To the best of my knowledge the failed parts are still available. I contacted the bbb who, in turn, referred me to the GMC customer service office. After contacting these people they file a report #1-408898915. They indicated to me that GMC would do nothing for me due to the facts that the vehicle was out of warranty and that I had not used a GMC dealer for the repair work. The repairs were #613. 59. The dealer would have charged me approximately $1,000 for this same work. They did give me the address of the GMC divisional office in michigan and suggested that I contact them to see if they will do anything for me. I will do this, but I have not done this yet as I do not anticipate a positive result from my efforts. I feel that this is a defect of the parts and/or vehicle. Especially since both the brakes and the tires out lasted the wheel assemblies. There should be an "implied warranty" that major components like these have a life expectancy that exceeds the written warranty.
