Belt noise

[djmanu]

Hi,
I'm being crazy ...
I have that belt noise since 2 months but cannot find where is the problem.
Went to the shop, they changed the belt and tensioner.
1 day after, same problem, went second time, they changed the altenator, 1 day later same problem ...
Went a 3rd time, they changed the water pump, 1 day later ... same problem.
They also changed some pulley and checked alignment, everything looks correct.
I really don't know what to check now, it already cost me a fortune without any results ...
Do you have an idea where it could come from ?
Thanks !

seems like the only thing left is the A/C pulley

First I'd find a different shop. They're not trouble shooting. They're guessing. I haven't taken a look in a while so I don't remember how many idlers there are. First thing you should do is remove the belt and make sure everything spins freely. If you feel any grinding then the bearings in that pulley are shot. Second, or maybe first, make sure you have the correct belt length. I ordered a belt for our 06 GT and it ended up being too long. This was after chasing the squeak for a couple days.

Thanks for your reply,
I think it's coming from the power steering because when I turn the wheel the noise changes.
Now I dont know if i will have to change the whole pump or only the pulley...
I hope it will work this time, it has been a costly troubleshoot ...

It might be just the pulley.
