I was driving down interstate 55 coming from sikeston mo headed to st louis with my family. As I was driving I heard a loud bang and the truck had begun to vibrate after pulling of I noticed that there was fluid leaking out. I had to have the truck towed back the mechanic assumed that the transfer case was gone out but upon removing the transfer case it was the transmission adapter had shatter I had many dealers look at the piece and they said they have never seen nothing like it. The metal gave away for no apparent reason nothing else was damaged except that transmission adapter. It was frighting for my family and myself I would like some answers on why this happened thank you so much.
2003 GMC denali front transfer case failure. While driving on the highway I noticed a loud noise for a few seconds, then it stopped, so I drove on home and the next morning I dropped it off at my personal repair shop. To his findings it was the front transfer case. So he called the local dealership and talked to someone he knew that worked at the dealership in the parts department and they told him that the dealership had repaired several denali's with the same or similar problem just this year.
The contact stated when making turns there was a screeching noise coming from the rear of the vehicle. In snowy conditions when the four wheel drive was engaged there was difficulty driving followed by another screeching noise when shifting from automatic to four wheel drive. The vehicle has been to the dealer for inspection. The dealer overhauled the four wheel drive, but noted all four tires were off balance and varied in size. This could possibly be the culprit of the screeching noise when turning. The tires have not been replaced.
We purchased a 2003 GMC Yukon. Before it had reached 3000 miles the neutral light came on on the 4x4 unit. From there it would shift itself into 4 low. We have had it into the dealer a total of 6 times now and they have replaced one of the components 3 times, two of the other components once. After the secon d replacement it started showing neutral again on the 4x4 unit. It seems as though the problems do not arise until after 1000 miles. The dealership service department told me that they have had a lot of problems with these units. We are trying to do a buy back but gm is dragging things out and giving us a hard time.
