2001 Dakota SLT, 4x4
It's developed this little squeak, like something needs oil, when
backing. It's not the brakes (or brake warning), I think, since the
noise isn't happening when I apply the brakes. Generally, it squeaks
once, like a door opening (squeeee), then stops. It may be related to
turning sharply, as I only notice the squeak when backing out of the
carport. It's coming from the back end, somewhere.
It's not very loud, I only hear it when I've got the window rolled down.
I've tried the brake setting procedures (driving forward/back and
braking sharply, but no change.
Is this just one of those sounds older trucks pick up over time, or
something that should be investigated? What might it be?
