Every once in a while at random times while it's colder than 30 degrees, I hear a loud squealing noise coming the front of the truck which ends up really squealing from the back. When I open up the back window, you can really hear it coming from in between the bed and cab. At first I thought it was the belt which is new as of this past summer so I sprayed some belt spray on it. It does not squeal in park, only while driving. Has anyone come across this weird situation? It's really embarrassing , almost more embarrassing than my horn issue! Thanks.
