I've started to notice a squeaking sound in front and back of the car- weird thing is though that it only happens when the temps go about 30 degrees and below. First I thought it was the suspension/shocks - well I've since replaced them, even replaced my sway bars -no change- then I though maybe the front air dam -but why only in the winter. Can't describe it in words but the closest I can describe it is when your shocks or coils are worn out and they make they squeaking sound or like a door hinge that don't have any oil or lubricant -anybody else have this problem maybe a solution.

 

weird

 

I got the same problem with my C5. I thought maybe it needed a grease job so I have on set up for next week. I glad you did the shocks, I thought that might be it too. We got a lot of road work going on in town and I thought going over the rough roads caused it. Let me know what you found out. I know mines underneath the car front and back.

 

Have you tried lubricating the sway bar bushings with Lithium grease?

 

Heres the Troubleshooting guide from the manual. Its for the rear but I guess the front is the same

1. Start the engine with the drive wheels off of the ground.
2. Shift the transmission into Drive.

Caution

Do not spin the drive wheels faster than 55 km/h (35 mph) as indicated by the speedometer. This limit is necessary because the speedometer indicates only one half of the actual wheel speed when one drive wheel is spinning and the other drive wheel is stopped. Personal injury and damage may result from high speed spinning.

Important

This step will require the assistance of another person to maintain the drive train speed. Do not use the cruise control to maintain the drivetrain speed.
3. Increase the drive wheel speed until the noise is at the most audible level.

Important:

Do not allow the stethoscope to contact any moving components.
4. Use J 39570 in order to locate the source of the noise.

Does either wheel bearing exhibit noise?

Thanks Deegee - that's very detailed But I did try to bounce the vehicle - no noise heard, only happens with temp of 30 degrees and lower - and only if I hit small bumps even getting off my driveway if I get off my driveway a little faster, weird thing is, when I back up on the driveway faster than I should, I would hear the noise only in the front but getting off my driveway I would hear the front and back - going thru small bumps on the road will make the noise. Replaced ym shocks with C6 Z51 shocks -no change, replaced the sways with '99 Z51 sways - no change -lubricated the sways before installing them -this started before I replace my old shocks and old sways and by the way -my car only have 20+ K miles -not really a high mileage car for an 03. Drove the car today about 35 deg where I live -didn't hear the sound - not worried -just annoying sometimes

 

Well, guess it's just me and Lone Ranger444 who have this problem. I did a search and came up empty

 

If it's below about 35 degrees I get the same squeaks until it gets warmer. I have no idea what causes it either...

 

I squeak too...
I think its from the front.
It is anoying.

 

Say hello to the Lone Ranger because I have squeek front and rear.

I replaced the sway bars and bushing with new z06 parts. No change.

I lubed with silicon lube the shock tops and bottoms (remember you can only dobber on vs total removal)

A frame bushings spray silicon

Still the f/r squeeks both left and right sides.

I am thinking shocks but with F45 . I have an extra set I bought from new car take offs during mod time so I am thinking of installing these. My thoughts are the shock strut rod is squeeking at the top where it enters the cylinder.

My C5 sounds like a log wagon below 35 mph (any temps) but above 130 varooooooooooooom..

So tell Clayton Moore and Diablo are not forgotten, neither is Tonto

 

That happens to me sometimes, too. I've noticed that if I change the shock settings from tour to sport or performance for awhile, the noise goes away. I can put it back on tour for several hundred more miles before that annoying creaking sound returns at low speed over speed bumps. That's the only time I ever notice it happening.
