2000 5.4, it runs fine, acts fine but makes a bad squealing noise that increases with speed. it was raining cats and dogs the other day when the noise started. new serpentine belt, alternator. its been two days since and it continues. i havent looked at it yet today but was wondering if anyone has had and solved the problem

thanks

 

Does it do it with the belt off? If not , has to be one of the front end components, just have to track it down, idler, tensioner, a/c, water pump, etc.

 

Well it went from a squeal to a bearing sound. So I got out the ol wooden dowel, found it to be the tensioner wheal bearing. Bought a new tensioner

Ps dont hit flood water doing 50
