2007 Avalance makes terrible screeching sound.
I have had my (new to me) truck checked out for this noise 3 times. The final time they
said they checked and greased all the brake parts. It is not the brakes because it
screeches as I drive. It is a terrible noise and has taken a lot of fun out of enjoying this
beautiful truck. My concern is that it is getting worse. Any suggestions would be greatly
appreciated before I call the garage again.
