Hi guys,

I didnt really find answers on this forum so i post a new thread.
I have a strange sound comming from under my car when driving.
It sounds like metal on metal, a loud peeping sound.
It has nothing to do with how fast or what road im driving.
The sound and frequence is always the same ( 10 mph or 100 mph)
It has nothing to do with AC/heather fan either.
When the cars parked an i rock/shake it i dont hear the noise.
Its not the suspention or exhaust.
Dealer cant find anything, went back 3 times.
IT DRIVES ME CRAZY!

Anybody any idea?
