1997 GMC suburban 2500 4X4 5.7 110k miles. started about a week or 2 ago, chirping niose, sounds like coming from under the cab not engine bay, but its hard to tell where cause I can only hear it when moving under load. doesn't matter what speed i am going, seems to chirp with rpm. anyone else had this issue? thanks. doesn't chirp in park, at least not yet...

Hi,
I really wonder what the noise is like you do.
It's like very thin, high pitched flashlike sound especially when I foot the brake or release. .

chirping noise underneath usually caused by worn universal joint on drive shaft
