    Whining from the rear

    Took my car out on a test drive after solving some irritating ticking noise and heard some whining noise from the rear of the vehicle. Almost sounds like one of those rubber toy chickens after they've been squeezed, but higher pitched. Most noticeable with the windows rolled down, and when the car is in motion at about 20-30 MPH without your foot on the gas.

    What did you work on last in the rear? Start there, also check all rotating parts for noticeable play.

      Haven't worked on anything in the rear of the car lately. The ticking noise that I had fixed was from the timing chain tensioner. I wish I could record a video but the wind noise from driving with the windows down would mask the sound.

        does it change in pitch ?
        first thing i'd check is the diff to make sure it has fluid and to rule it out. they are getting harder to find. after that i'd suspect a rear wheel bearing or maybe even a fuel pump. fuel pumps will whine when they start going bad.

          The sound loops pretty consistently, with no changes in pitch.

            Is your mother in law sitting in the back?

              edit : the "loop" should change a bit with the speed.
