Help, anyone....

a couple of months ago I had a belt like squeal in front of motor, replaced serpentine belt. Still makes noise. replaced idler pulley, still made noise. Replaced adjusting pulley, still makes noise and getting louder. Seems noise is really noticeable when laying on back looking up at harmonic balancer. Will this pulley make that much noise? The rubber grooves which belt ride on show sighns of wear and peices missing. will this cause noise? I can't afford to replace anymore parts without knowing exactly what it is, and this I hear is not easy to change either. I have 62000 miles on it and seems to get worse all the time. It will quiet down alot after driving for few miles. After sitting for half hour or so it is loud again. Anyone have any ideas?

Moved from tech corner-

If your new belt was installed correctly a few months back and there are pieces missing you have something wrong somewhere. Check all of your pulleys and pumps for bends and defects.

belt is not what is missing peices, but the rubber around the harmonic balancer pulley, the belt seems to be ok as far as falling apart. I have inspected all the pulleys and replace two. The ac pulley seems fine as well as powersteering. Noise seems to be under truck more than anywhere else.

Any odd engine vibrations?

62k is low mileage for that sort of problem.

The harmonic balancer may be difficult to change, I don't know its proximity to your radiator, but I believe it can be pulled without removing the radiator, you just need a puller.

Look for Aldive's thread on underdrive pulleys, I believe he pulled his to install the new pulley.
