Been forever since I have been here.....too long actually.
Ok here is the story, My 05 has developed a belt squeal that I cant seem to get rid of. It always has seemed to go threw tensioners and belts more than I think it should be there is something going on that I cant figure out. I am on my 4th tensioner and 3rd belt in the last 2 months, After the first tensioner belt swap the squeak was back in a week so I thought maybe it was a water pump even though it was fairly new, and the idler on the top above the fan had some slop so I replaced both, the fan bearing felt really good so I left it alone. I assumed it had to be something that ran on the back of the belt because a few drops of water would quiet it down until it dried. Still squealed so I took the tensioner back and got it replaced, squeal went away, thought I had it fixed. Week later it came back so I got a better belt and a 3rd tensioner and once again it only lasted about a week. I went and bought a cummins (dayco) tensioner and that seemed to fix the problem for about a week so I went and bought a mopar belt thinking maybe that would help, after a day the squeal was back. Last thing to try was to replace the fan bearing knowing it will probably not fix the problem but its the last thing that the back of the belt rides on and as expected it did not help. The alternator bearings seem a little noisy but it still feels smooth and no end play, the AC pump bearing is probably the noisiest, the PS pump was replaced about 30k miles ago when I rebuilt the front end and steering system. The fan clutch still feels smooth but its my next thought to replace because it seems like the noise is coming from the fan pulley.
Any thoughts or ideas?
