 It has been determined that water has contaminanted the oil in the rear differential causing a mechanical failure. i have been informed that my extended warranty does not cover this issue even though gmc is aware that problem with a vent tube location is one source for water infiltration. i have a gmc document with specific instructions for mechanics to check for the improper vent tube location if water is indeed found in the rear axle fluid. *jb

 Dt: contact states above the rear end differential there is a vent tube placed between where the truck bed stops and the cap starts, and there is about 1 -1/2 inch space left between. this space lets water collect, running down the tube, destroying the oil, and causing the lubrication on the rear end differential to be destroyed. a technical service bulletin for september 2004 discusses the same component.*ak the rear seal had blown out which caused grease to escape. the consumer was told the entire rear end including the axle bearing and seals had to be replaced. *jb
