Well, this is a long shot, but here goes...

I'm wondering if anyone has had a noise problem similar to one I am now
 experiencing. The noise is a squeaking sound from the chassis heard when
 driving over any kind of rough pavement at any speed, even at a crawl.  
The noise definitely has more of a rubber-to-metal than metal-to-metal 
sound, and I have done everything short of dip the entire vehicle in a 
vat of silicone lubricant in an attempt to cure the problem.  The noise 
appears to be coming from the front of the vehicle, perhaps the passenger 
side (although these noises can be notoriously misleading
 as to their source).  Unfortunately, I cannot duplicate the problem 
while the vehicle is stationary.  So far I have lubricated (with silicone 
spray):

all suspension bushings and joints  (ALL of them)
all rubber exhaust hangers
all along the windshield rubber joint
radiator mounting
engine mounts
just about everywhere else I could think of...

This noise is very annoying, and it is driving me crazy...  especially 
when I
 consider that a couple of grams of lubricant in exactly the right place 
would
 probably cure the problem for the life of the car...   

One more clue...  the sound is only heard after the vehicle has reached 
full operating temperature.  Nothing is heard first thing in the morning 
for the first 10 miles or so...

Any ideas?

Thanks in advance--
