I was driving home from work which is 1.5 miles, when I heard a thumping sound, and it seemed as if my rear wheels were not turning. I had a friend tow it to the dealer cox Chevrolet in bradenton, fl, and they told me, that the rear end (spider gears, and bearings) were needing replacing but are not part of the power train so it was not covered under warranty, and it would cost me $2600. I had him tow it again to a local transmission shop and they told me it was common in that year of Chevy trucks. I also needed both clutches replaced in each rear wheel, cost was well under the dealers charge. The owner of the transmission shop informed me that he has replaced a couple 100 of these and there should be a recall on them. I could have been in an accident when the wheels locked.

This is problem(s) that has been intermittent for a couple a years shortly after I purchased the vehicle but did not mention anything because it was so intermittent....first the illumination level seemed to dim every once in a while for many areas such as the gear (prnd), the speedometer, the temp control levels. Next the speedometer did not reflect correct speed sometimes even when you were parked. These symptoms were initially intermittent but now are more predominant. Now this at times is a real problem and even a safety issue.

The 4 wheel drive buttons fail to work every so often. I was coming home from ann arbor, mi. One night and my indicator light said I was in neutral for some reason. I played with it for a bit and no luck. My friend was with me and he owns a repair facility in South lyon, mi. He knew what was wrong! the encoder motor for the transfer case is bad. It is an electric item and fails. The encoder motor is what shifts in to 4 hi, 4 low, auto 4 wheel and 2 hi. This happened again toward the end of Feb 2010 when my truck would not shift at all, 2 hi was my only option. Another friend of mine has a 2004 Silverado and her encoder motor went bad on the freeway. Her problem was that her truck threw her into 4 low while she was at 70 mph. Omg is that safe"??" GM needs to do something before people start to crash or worse getting hurt and dyeing as a result.
