low pitched howling sound from Santa Fe

My 2002 Santa Fe with 37,000 miles has developed an intermittent howl
from I think somewhere in the front end. The sound is like metal on
metal without lubrication. The car has been to the dealer 3 times, but
of course they never hear the noise. Sometimes it occurs when the car is
driven slowly and sometimes at highway speeds. There is no vibration.
Just the howl.

My 2002 Santa Fe AWD does the same thing. Any solution would be
appreciated.

I've heard a few times a moaning or humming noise, but only driven at slow
speeds. In these cases there was some sort of vibration set up in the
front brakes. Removing the pads and coating the caliper contact points
with grease resolved the issue.

I'm doubtful we're talking about the same issue, though. In my cases, it
would always go away when the brakes were applied, even slightly.

That is exactly what mine does. Apply the brakes and the sound goes
away. I'm not certain that it is only at low speeds, but that is when
you can hear it.

Interesting. I was thinking it might be the brakes, but why hasn't the
dealer checked this when I had the car in the shop with this complaint?

It's possible they did check. The problem is that there's nothing abnormal
seen. The first time I had this happen, I couldn't duplicate it on the
customer's first visit. On his second visit, one of us drove the vehicle
(I can't remember which) to the owner's specifications and we were able to
make the noise occur after a few miles. Even after hearing the noise, I
had little idea where it was actually coming from, and the vehicle
wouldn't do it on the lift in the air with the wheels turning.

What I then did was to call Hyundai's technical assistance line to see if
they knew anything about this. The assistant said he had a similar case
on the other side of the country, would call to see what they found, and
would call me back. He had me lube any caliper to pad contact points and
recheck. After the test drive with the customer, I knew how to make the
noise occur, and lo and behold, the noise was gone.

I've seen about three of these now, but never have I actually been able to
see any physical problem with the brakes.

Thank you. I'll have my local dealer check with technical assistance and
see if they can make the noise disappear.

I also have a 2002 SantaFe, but, i dont hear any unusual noises. Can u
better describe the 'howling noise' you hear ? If it sounds like metal
on metal...that would produce a grinding noise or a creaking sound, no ?

THAT'S BECAUSE DAVE'S A BLIND, DEAF, AND DUMB WEBTV ASSHOLE

The one I've experienced I've seen only on a few vehicles and sounds like a
very loud humming noise. If you've ever heard the loud hum from a bad Ford
idle actuator, it sounds nearly identical.
