      Blow across the open top of an empty beer bottle—the air in the bottle will resonate and make a tone.

      In my Mk3 I hear that very tone sometimes. Hard to place it. Sometimes it seems to come from rear, sometimes from everywhere.

      Tone seldom occurs in cold weather, but now that it's warm I hear it. Tone is intermittent. Tap the brakes—tone stops. Wiggle the steering wheel—tone stops.

      No tone when braking. Tone doesn't change with speed—sounds the same at 20 mph as it does at 40 mph—except that at 40 mph the howl is less distinct because there's more road noise.

      Ideas? I'm going to check rear drums for interference…

      Could be your wheel bearings going bad. Jack up and give the wheel a spin, see if you can feel or hear anything grinding.

      X2. Jack up the rear and give the rear wheels a spin and side to side and up/down wiggle to check for play.

      Def a wheel bearing. If no play is present you can alway lift the car and spin the **** out of the rear wheels and listen to the wheel bearing with a stethoscope. Or if you think it's the fronts you can put it in drive and and put ur scope on it.

      eyepoppet, that makes perfect sense except for the 99 percent of the time when there is no moaning or howling noise whatsoever…

      Do you use your parking brake? How is your adjustment on the shoes? E-brake cable adjustment and condition?

      Yes, I use the parking brake. The cables are are probably stretched—a big pull is needed to get them to hold. Rear shoes aren't dragging.

      Cable can be adjusted. You will need to remove the arm rest to get to it.

      Waste of time trying to adjust cables that are stretched beyond specs. Need new p brake cables.

      Do you mean that engines, transmissions, ABS, timing belts, cylinder heads, and even ashtrays can be replaced but it is not possible to replace parking brake cables?

      Thanks for letting me know; I would not have imagined such a situation…
