Help stop the squealing! Fan belt.. Arrghh!
I have a 97 2.5L TJ and a while back the I started
to hear a loud squealing noise come from the engine.
It starts about 2 or 3 miles into any driving trip
and only occurs when I am deacelerating, or idling.
Since I have about 130k on the jeep I immediatly thought
it must be the belt.. so I replaced the serpentine
belt and tensioned it properly.. it still squealed..
So I played with the tension for a few weeks incase I was
on crack but I couldnt get it to stop.. So I figured
it might be a cheap belt, and replaced the belt again
with a top of the line belt from napa. It is STILL
squealing despite being tensioned properly.
All the acessories seem to be working fine, and turning
them on doesnt change the pitch or reduce the sound (AC).
Any ideas what I should do next? Its driving me crazy.
Thanks,
Mike

That sounds like a dry bushing on the idler or adjuster pulley. On the
4.0 there are two bushings and a big washer and a bolt that all have to
be ordered separately when they wear out. You can try to spray some oil
into those bushing areas to see if it helps for a while.

Watch your fingers but with the engine running, lightly
touch the sides of the belt with a bar of soap and notice
if it goes away. If it does then the odds are your harmonic
balancer has started to break down and walk off it's rubber
isolator. Read here.
