Ok I'm stumped on this....
When I turn at low speeds (just above idle) and mostly turning left I get an intermittent squeak or chirp coming from what seems to be the drivers side. It isn't caused by the brakes because it makes the noise even without pressing the brakes. My rotors don't look bad and seem smooth.... My rear pass side rotor has a small line in it (like piece of dirt or sand was caught) but i don't think that is causing it cause its coming from drivers side front. I don't know what this could be? Any ideas?


I have a 2004 fx4 5.4l with 96k on it.

 

Double post.

 

Could be bad hub.

 

Wouldn't that make a humming noise and not a squeak or chirp?

 

Not necessarily. Metal on metal will squeak. If you Had a 97-03, I would also have mentioned CV joints. However the 04 up CV joints should not be turning, unless you have problems with your IWE's.
It could also be the brakes. When the noise is happening, and you press the brakes, does the noise go away? Just because you are not using the brakes does not mean you can't have a metal on metal contact.

 

That makes sense. I will go out and drive it and see if when I brake it stops. Could a bad bearing allow the brake to rub even if my pads are fine?

 

Lots of things can make a noise without braking, including a rock or stone. I would check that rear brake as another thing that will make a line in the rotor is the rivet on the pads when the pad is too worn.

 

Ok so I took it out and only heard the squeak when I came down off the curb in my driveway. I got back in the garage and got on the step bar and moved up and down. I then moved the truck side to side and heard a squeak. I don't know if this is the same squeak but I took a vid of it.

 

Anyone?
