The largest(damper pulley, I think) squeaks and wobbles. I have had it to the Chevy place twice and $600 later it still squeaks.

Hi Ann:
Just an idea.
You could also check the water pump bearing.
Slack the tension, then see if the fan will wobble if you try to move the blade tips at right angles to the plane of rotation.
I'm assuming the belt is in good condition.
The other possible is that the drive pulley (harmonic damper) off the crankshaft has failed. If you shine a flashlight at the damper while the engine is idling you will see the wobble if this is the problem.
Work Safe! Moving parts can bite your fingers off.
Hope this helps.
Cheers

Check the belt alignment and also check for other worn bearings. Crankshaft damper may be coming apart.

Hi, assuming you have the 2.5 liter engine, your damper is integral to the pulley assembly as shown in the second figure below, so there is only one part involved. You can see an example of the part here: http://www.autozone.com/autozone/parts/Dorman-Harmonic-Balancer/1999-Chrysler-Cirrus/_/N-jddk1Z93y2h?counter=0&itemIdentifier=917091_0_0_
If you look carefully at the pic below, you can see the rubber torus inside the pulley. The rubber is what fails and causes the pulley to wobble. You may need to borrow a puller to get the pulley off.

2.5L Engine

1. Before servicing the vehicle, refer to the Precautions section.
2. Disconnect battery negative cable from remote negative terminal on shock tower and properly isolate to prevent accidental reconnection.
3. Remove or disconnect the following:
   
   Belt splash shield Accessory drive belts. Refer to Belts. Crankshaft center bolt and remove crankshaft damper.

To install:

1. Clean crankshaft snout and crankshaft damper bore.
2. Install or connect the following:
   
   Crankshaft damper. Crankshaft bolt and torque to 143 ft. lbs. (182 Nm) Accessory drive belts. Refer to Belts. Belt splash shield

That is the idler pulley and they do go bad and need replacing if wobbling or squeaking.

The bottom pulley on any engine is attached directly to the torsional vibration damper which is attached to the crankshaft. That pulley drives the serpentine belt and has no bearings. First thing you need to do is find out if the pulley bolts have become loose or if the damper on the crank is loose.
If you find the pulley loose, if the bolt holes are not elongated, just tighten it back up. If the damper is loose, remove it from the engine (puller usually necessary) and inspect the crank snout and the alignment key for wear. Any damage to the damper requires that it be replaced. If the crank snout is severely damaged, that requires that the crank itself be replaced (very expensive).

no. there should not be any wobble to your harmonic balancer pulley! any wobble to the bottom pulley,means it's out of balance. either a belts too tight,or a harmonic balancer bolts loose. the other belts contribute to the wobble once it begins. check the tourque on the harmonic balancer bolt. it should be about 180 footlbs thank you for choosing fixya.com.

Crankshaft Damper Pulley-- gone bad,replace it

You need a harmonic balance. Very common problem!

There is a pulley out of alignment. Only 1/8th inch out will cause a serpentine to sqeak.

your power steering pump is probably starting to go out, its best to have it changed before anything like that happens
