Hello all,

i have a 2010 3500 with a 6.7. Truck has 60k on it, I have had this issue since the truck had around 15k. The dealer has replaced all pulleys water pump, alternator and has put 6 belts on it. Belt last 2500 to 6000 miles then it starts squeaking. They and myself have made sure all pulleys are unlined. Anyone else have this issue? This is my first time joining a forum.

Sorry forgot to put that when I asked the question, yes they did replace it.
