Wheel Bearing Hum?
I have a loud humming sound coming from right rear wheel. It is loudest at about 40 mph, but it's getting worse, and I can hear it at most speeds now. The noise goes away when I turn right, and it also goes away as soon as I touch the brakes.
It's a 2001 Jetta, 200,000 miles. I am assuming the wheel bearing is going? The drivers side went a few months ago, but that was just a growling/grinding noise. Anyone had a bearing make a humming noise?

Yes I had a wheel bearing like this. Drove me crazy. Took it in, they taught it to sing Freebird.
Much better.

Yup
At first thought it was tire noise. Would stop when the steering wheel was turned a little. Time for a new bearing.

My 94 VW rears hummed at speeds above 70km and weirdly only in fifth gear. It was a pulsing hum. At first I thought it was the gearbox.
(@160,000km) Swapped them out with new rear disks... Easy job! I've bought the parts for the fronts but all is good right now.

Yes. And after 200 k miles you're really asking this?

Just went thru a car not tracking true not hardly any humming but not driving true. After 112K on the Audi figured it was time for wheel bearings, so 4 new ones went in last week. Amazing for 2 days then the humming started, back to the drawing board, lifted car and found the culprit, left rear was a bad bearing from the getgo. Called the supplier up and had a new one sent and installed 3 days ago and finally peace and quite and car has no more pulling.
The cause is the great crap they spray on our roads in the winter that eats bearing, so out here in the mountains, bearing now will be a change job every 60-70k miles.

 I've replaced all 4 on our Highlander and one of the new ones ( lasted a year) had to be replaced already. Never been able to understand the reason they went with non grease-able bearings

I replaced the rear bearings in my 01 Jetta last year 300K+ miles. We had to do both, we could not figure out which one was making the humming noise.

I'll give you guys the trick to determine which bearing is making the noise/rumbling. Taught to me by an old timer 25 years ago, it rarely lets me down.
Diagnosing from the cockpit can be deceiving, but usually , if you are turning to the right, and you hear the growling, it is coming from the left bearing which is now loaded with the vehilces weight. What I then do after a test drive, is raise the vehicle, and get a firm grip on the control arm, or spindle of what I think is the affected wheel, and I spin the wheel by hand. You will be able to feel the roughness in the bad bearing. If you have doubts, spin the other wheels while holding on to the arms/spindles, and you will be able to tell which ones are silky smooth, and which one is humming. On awd drive vehilces, or or trucks, where it is often hard to manually spin the wheel fast enough, I will put the vehicle in gear, and let all the wheels, spin and CAREFULLY grab hold of the knuckle and feel for the roughness. I will also sometimes use a stethoscope for this. Careful here, you could rip your arm off if the wheel grabs it.

fred: The FWD auto could be put in [D] on the lift, at idle.
(.......Cavaeate: A risky proceedure...............) Hold one tire still. Then the other. Then isolate inner(dif/etc) vibrations vs. outer vibrations through the halfshafts. |
