Bearing/Belt squeal

[GRFDave]

I have had a slight squeal for a couple of weeks and I thought I would get it fixed early so I replaced the Tensioner, Idler and the Belt. The squeal got remarkably worse so I read the various forums and saw that the alternator is usually the culprit.So off the the store I go and get a new alternator, now the squeal is amazingly loud! HELP, what is next?

My power steering pump siezed up did not hear a thing. It happened on a very long straight road so I did not know for several miles until it over heated due to the belt coming off after the plastic pulley blew apart. Good luck or better luck than I had...

your harmonic balancer is about to go. be careful.

Are you sure it's coming from the belt drive? Start up the engine with the belt off. Not sure what forums you read but squeals on 95+ 3.0s are more commonly the CPS

If the squeal goes away without the serp belt on then it's probably a misaligned tensioner causing the squeal. See the above belt squeal thread on how to fix it.
