Duramax Squeaks Constantly

Volume 1 Issue 4 - Duramax Issues and Answers

My ‘03 Duramax keeps squeaking constantly and increases with the RPM. I've taken it to the dealer several times and they assured me the problem was fixed. It would quit for a while and then a few weeks to a few months later it would reappear. The last time I took it in under warranty they replaced all the pulleys on the front end with new ones from an 07 Duramax. A few months later it started squeaking again, and now it is out of warranty. How do I turn my Duramouse into a Duramax?
