Hello. I was wondering if anyone has had this problem also.
After 10 min. of driving and truck is warm, there is a constant high
pitch squeal or whine whenever the truck is coasting, gearing down or
braking. The pitch is constant. It does not change with engine speed or
transmission selection. The noise disappears under load/ acceleration.
It can also be heard during idle. I've taken it to a garage. The
mechanic mentioned it may be coming from the distributer. Truck has
been in dry storage for 5 years. All fluids checked and replaced. Belt
is tight. Any thoughts?? Thank You

It's a vacuum leak. The times at which you hear the noise is when the
vacuum pressure is highest. When you push the pedal down, you decrease
vacuum. Look/listen for a split hose or maybe a leaky carburetor base
gasket.
