I have an '04 accord v6. I recently replaced my alternator and drive belt. After a couple of months, the idler pulley started squealing and I had it replaced, then I replaced the tensioner assembly. A few days later it sounds like my power steering pulley is a new culprit. Has this happened to anyone else? Do I need to replace the power steering pump, or just the pulley?

 

I think the bearing under the pulley is part of the drive shaft of the power steering pump. The pump likely needs to be replaced.

It is strange that the pulleys are squealing after the alternator replacement. Is it possible the alternator pulley is out of line? Is there any damage on the new drive belt?

 

If you use a bit of belt dressing and it gets quiet, then you know it's the belt sqeaking not the bearings.
