Glad I came upon this! My 2003 made the exact same same squeak and then the belt went very loose and is half off the drive pulley. So, I will replace the belt, idler and tensioner.
I did just the opposite, I thought it was the tensioner pulley which I replace the whole thing but still got the squeaky noise so hoping it’s the idler pulley, wish me luck 🤪
hello - i have the same problem with my 5.9 - just started to get really bad lately (+300K miles) and i am interested if you found out what the problem was??
I have a dodge Dakota sport it's doing the same thing when you have the chance can you comment and let me know what the part was you had to fix it. I can't figure out why mine is making the loud squealing noise it does it when it's parked and it does it when I accelerate
Hey i know this video was three years ago you probably have the issue fixed idk but i had the same problem with 2003 dodge durango and come to find out it was my alternator.
