    Ideas for nissan problem

    1998 Nissan Maxima

    Drive Train / Driveline

    Making Noise, when driving, always

    There is a fairly loud hum or groan that matches vehicle speed. Not
    noticeable
    outside the vehicle (driving by). Barely noticeable at 5mph but gets
    significant at 20mph. In or out of gear doesn't matter, even with engine
    off
    (coasting, in neutral). Touching brakes or braking doesn't change the
    tone,
    but drone lowers in pitch only because vehicle slows. Turning has no
    effect
    either direction, sharply or gradually. Bumps have no effect.
    Transmission
    appears to be shifting normally with no slipping. Holding it in each gear
    has
    no effect and when using engine braking (2nd and 3rd), does not change
    tone
    (except pitch change as vehicle slows).

    Wheel does not pull to the right or left while driving/coasting. Brakes do
    no
    appear to be dragging, or overheating (Brakes were done about 1 year ago,
    10K
    miles since) Parking brake is not on and cable is not too tight when it
    is
    off. Nothing is rubbing on the tires or CV shafts. CVs seem tight with NO
    noticeable play at all.

    This came on fairly suddenly, not built up over time. about 20 miles since
    and
    it hasn't gotten worse, yet.

    Bad wheel bearing?

    I agree. Bad wheel bearing. And to find out which side it's on, drive
    on the highway, about 60 mph, windows closed, radio off, ventilation
    off. Take a gradual right turn or left. If the sound gets
    louder/higher as you turn left, it's the left wheel. The right, it's
    the right wheel. The turns are making the inner wheel spin faster than
    the outer wheel, therefore the wheel with the bad bearing will be
    turning faster, and hence humming faster, too.

    Could be the tires have a wierd wear pattern, many people get fooled into
    thinking it's a wheel bearing when they hear this. If you can tell which
    end of the car it is, rotate the tires and see if the noise moves. FWD cars
    do this worse than RWD cars do as the rear tires can get a wierd wear
    pattern if not rotated real often, like every 7500 miles or so.
