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.

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.
