2001 Accord - loud rear road noise over 40MPH

Hello,

I have a 2001 Accord EX (4-cyl). While driving there is rear
undercarriage noise at all speeds. The sound is a low frequency
vibration that varies with the current speed being traveled. The
sounds appears to becoming equally from the rear left and rear right
corner of the car. There is no connection to RPMs or engine activity.
The faster the wheels spin, the louder is gets. At 40MPH the vibration
hits a painful, headache inducing, frequency. The faster I go the
higher the frequency. 40MPH is bad, so is 65MPH, but the sound is
always noisy. Back seat passengers really notice it.

A full tire rotation made no difference. Now what?

Thanks!

Wheel bearing?

This may sound strange, but if you haven't already done so, get a can
of silicone spray and go over all of the weather stripping in the
trunk, around all the doors and around the hood. Make sure you also
get the bumper stops for the trunk and hood.

Also, undo and reseat the spare in the trunk and check to see that the
jack is stowed away tightly.

Grumps,

What might a repair like that run for a wheel? For both rear wheels?

Grumps,

When was the last time you rotated your tires - badly cupped tires will
make a hell of a racket - rotate your tires so that the back end up on
the front - when doing that check the wheel bearings by grabbing the
rear tires at the 3 and 9 oclock position and pull back and forth -
should be very little slop - do the same at 6 and 12 - you do this with
the rear end jacked up.

I replaced rear wheel bearings on a 80 accord only to find out my tires
were cupped. Rotate your tires every 10K minimum and don't let anybody
use a impact on the front wheels - they will warp your rotors. Had
that done to me also.

do yourself a favor: learn to crosspost. respondees to one group are
not seeing the responses of the other.

First, you have to ascertain that is the problem. It could also be
suspension related etc.

Assuming that there's nothing special about the bearings (I'm not that
familiar with modern Hondas), it would be a relatively inexpensive fix.

Early Odyssey had a mess of wheel bearing troubles. Check out the TSB's
and see if anything sounds familiar . . .
