Cummins3 mine were changed in July as well and there was no improvement, it may have even been a little worse. They were still building new production trucks with the same bad mounts at that time.
g00fy you will turn blue in the face if you wait for the dealer to call you. I called my dealer four days after the TSB was released and they said they hadn't heard anything, the advisor took down the TSB number saying he would look into it and call me back. Four days went by and I didn't hear anything so I called the parts department to confirm availability of the required parts and everything was available. The parts department transfered me to the advisor that never called me back, he said he looked over the TSB and that it said something about loosening the bolts and centering the cab on the mounts then retorquing. I asked him to pull the TSB up again and look at it closer to see where it mentioned replacing the two cushion assemblies and ten bolts. He put me on hold to check availability of the parts came back to say they were five days out and would call me when they are in. Six working days later I called the parts department to see what the status was, parts were in but I never got that call from the advisor. I had actually called two days in a row and left messages for the advisor but never heard back so I showed up yesterday to drop the truck off and he was a bit confused as to why I was there and proceeded to tell me that the parts weren't in yet. I told him the the parts people told me they were in so he called over to the parts department and they told him everything was in. The communication internally is just as bad as between the service department and the customer. It is sad but you literally have to do their jobs for them in order to get **** done, it is not that difficult.
