I have a few sqeeks in the cab and can't pin point them so I can fix them. 1 sounds like it is coming from under the dash on the drivers side. I looked under there and didn't see anything that would cause it. Unless it's coming from the sterring shaft. I only hear it when I hit a bump with the left front suspesion.

I also think I hear one coming from the back window area when the rear window is open.

 

My tailgate had a squeek. i just put a little greast where the latches are and bingo, good for a while.

 

The rear window open squeak may be the tailgate since you can't hear it with the window closed.
