Squeak and groan
Car is a 99 WS6 M6...
When it's cooler outside (around 50-70 Fahrenheit) or humid and I first start the car up and take off, I hear a squeaking sound that gets faster as the car goes faster. It almost seems like its coming from right below my feet. However, as the car warms up, it gets quieter or goes away completely. Any thoughts?
Also, occasionally when I hit a bump or an indent in the road, I hear a metallic groaning sound that sounds like it's coming from the rear of the car. Also, a friend of mine said my right rear wheel visibly shakes when I'm at 55mph or higher, but oddly enough I don't feel it in the car. Any thoughts on that too?

hmm, well that would mean it would pretty much be something w/ the wheels , or something from driveshaft back... if it was tranny or engine, the frequency would cycle w.r.t. them...
could be a brake caliper gummed up a bit, causing pad to rub and squeak... could be rotor warped, causing pad to rub/squeak..
is the squeak audibly loud, or faint?

It's audibly loud...but it seems to go away the more the car moves.

something brake rotor-ish would be my first suspicion... any chance you have warped rotor or two? when you apply the brake to you get pulsation/feedback in the brake pedal?

im pretty sure your first problem is your AIR pump. mine does the same but luckily ill be taking it out when i do a header swap. i wouldnt even worry about that one

I removed the air pump a long time ago so I know that's not it. Occasionally I'll feel feedback in the pedals if I apply a LOT of brake, but for the most part it's a smooth ride

Ok found out what it is...had a second pair of ears listen and it appears to be either the shock or spring in the front on the drivers side. Thanks for all the help though, guys

hmm, but you're saying the squeak sound linearly increases w/ speed still?.. if so, i still think it must be something w/ the wheel/hub/bearing/brakes..????

It still does but like I said only when the temperature is about 50 degrees or below. Haven't heard it in a while of course
