2005 Chevrolet Silverado 2500 hd 4X4 lt 52,000 miles transfer case replaced due to "pump rub".

Bought 2005- 2500 4X4 Chevy. Silverado 4 door truck new from herndons Chevy. In orange, va. Several months after I bought it I started hearing a knock when I stop or take off or accelerate after slowing down. It sounds like it is somewhere in the transmission area. It did not do it all the time and the knock was not real loud. Herndons has checked it several times and says it is a slippage and is normal. It now has gotten much louder. It is non stop now. Everytime you accelerate from a slowed down or stopped position and it can be heard from people standing out away from the truck. I am very frustrated. I am going to take it back to herndons next week but I bought they will say it is anything wrong as before. I have never heard a vehicle sound like this. It is embarrassing to drive. It has approx. 34000 miles on it now, but the problem began a few years back. Herndon should have it documented. VIN# is. Also right after I got the truck I started it up and backed it to my shop cut it off. Started it back up put it in drive and it went backwards. Cut it off-restarted it put it in drive would not move-put it in reverse-would not move. Cut it off-called herndons they came out -I started it back up and it moved like it was suppose too. It did it once after that was a good while longer. But instead of not moving it hesitated for a few minutes before it moved. Herndons checked it but could not find anything wrong. So far it hasn't happened again. I know something is wrong with this truck. The loud knock is not normal for any vehicle. I am afraid that something is going to break loose and I am going to have an accident while driving. Please investigate this problem and see if there has been any other complaints like mine.
