    Default Whining/grinding noise on Chrysler PT Cruiser

    I've got a problem with my PT Cruiser and thought I'd ask the group
    here about it.

    At about 20 miles an hour I start to hear what sounds like a grinding
    noise. It starts low in pitch and gets higher as I go faster.

    My mechanic was dismissive of the problem and didn't even address it
    when I last brought the car in (major tuneup.) When I asked later we
    went for a short ride and he said it was due to shocks and struts
    deteriorating, that the tires were wearing unevenly and that's what
    was making the noise. All plausible, but it would cost in the area of
    $900 for shocks, struts and new tires. I'd do it, but I'd want to be
    sure I was was addressing the actual problem.

    My mechanic doesn't seem to think it's dangerous, but I'm not so
    sure. The noise is pretty loud inside the car but apparently not
    outside. At least, in six weeks of this problem no one has turned to
    look at the car as I go by.

    Alignment is good. I've taken the car out of drive and in to neutral
    at several speeds and the noise doesn't change. Also doesn't change if
    I hit a bump and I'd think I would get a momentary blip if it were
    tires. I'm thinking something inside the wheel, perhaps A-Arm or some
    such.

    Any ideas? I plan to check in with my mechanic again this weekend and
    would like to have some possibilities in mind.

    Wheel bearings or CV joint ? Just guessing.

    I was thinking along those lines too. A worn-down bearing might make
    that noise, or at least so I was thinking.

    To add to the mystery, I forgot to add this before: The noise is
    significantly less when I steer right, even slightly like on a long
    slow highway curve. Seems barely louder when I steer left but the
    main difference is from straight ahead to steering right.

    Turned out to be a worn hub bearing on the left side. Got it fixed.
    Thanks peeps.
