Hi everyone, I have an 03 Suburban that is making a noise that sounds like your driving over a rumble strip. So far I have taken it to two mechanics including one dealer and no one can tell me what the is noise is. There is a slight vibration but can't tell where it's coming from, mostly just a loud noise.. Can anyone help?

 

Welcome to the forum
Might try having the tires rotated to see if the noise changes...

 

Does it happen at all speeds? Does the frequency change with speed?
