Can anybody recommend a dealer in the Nashville/Springfield Tennessee area that actually knows how to work on the cummins engines. My truck has developed a knock. I have had it to the dealer twice and they just connect it to the DRB and tell me that everything is within spec. I have ven taking the service manager for a ride with the DRB connected and he said that he could hear the noise and feel the vibration. They replaced my driveshaft and the knock is still there. I called Cumberland Cummins. They said that they are not able to work on anything newer than '02 since Dodge took over all of the electronics.
HELP!!!
