While you hear it steady slightly turn the wheel and listen for a change. If it gets louder going left the right is most likely the problem and vice versa. Personally I have rarely seen both go bad at the same time, but I have seen it. Had the chirping noise in my 2002 MC pace car...took some WD-40 and sprayed behind the alternator pulley while the engine was running....chirping went away in a few seconds....tells me i will need a new alternator soon.....bearings on their way out!  Sometimes the serp belt can cause a chirping noise. After a while the belt can form a glazing on it which can make it slip slightly making the chirp. Belt dressing and WD-40 or similar lube can help but not a perm fix. Try a new belt, it's a lot cheaper than an Alt and if you end up having to replace the alt you will already have a new belt.     (in reply to rcohen) Post #: 24

If the alignment has been out for a while it most likely has caused this problem. Rotate the tires from front to back and see if the noise changes from front to rear when you do it. _____________________________ Proud owner of a 2006 Monte Carlo LTZ Laser Blue (in reply to bilms01) Post #: 25

It sounds like a huge cricket is trapped under my hood! Its not my belts I changed those. What is it!? I would check 3 things here 1. Alternator (GM does not put the cap on the rear bearing anymore) 2. Belt tensinor and all the other ilder pulleys (use the screwdriver like someone stated) 3. A/C clutch plate on front of the A/C compressor, the fingers on the plate will break cause the plate to be loose and rub the pulley that the belt goes around. The noise will sometimes stop if you turn on the a/c system Keep us posted on what you two have found please _____________________________ Proud owner of a 2006 Monte Carlo LTZ Laser Blue (in reply to Mrrench) Post #: 26

RE: Weird loud chirping noise - 4/9/2007 1:02:40 PM    rcohen Posts: 203 Joined: 11/7/2006 Status: offline It was the hub bearing, I had it replaced ($400 including labor--ouch!).  My tires are brand new and I just had my car aligned so hopefully we are set for awhile.  I hate seeing parts for 90$ and than having sumone charge you 280$ for em.  Wish I had a lift! _____________________________ 2001 Monte Carlo Ls custom cold ram air intake, 180* T-stat, Ported intake + 65mm TB + spacer & bypass, magnaflow downpipe & cat w/ u-bend delete, dual flowmaster 44's, UD pulley, slp grill, xenon headlights (in reply to Mrrench) Post #: 27
