woosh, woosh, woosh

[pconroy]

Coming from driver's side front wheel. Frequency increases with speed. 40,000 miles. Guesses??? Bearings???



I lifted the front wheels up and spun the wheel. My initial gut feel was brake, not bearing. Out of round rotor???


I've got a non-contact thermometer. I'm thinking of driving a bit and checking temperatures. Or would that be a waste of time in trying to figure out what's the cause?



Ugh - no good places close by that I'd trust to do front end work on this thing.

I have seen where a bad belt in the tire can cause this. When watching the tread while spinning the tire, sometime you can see a ripple where the tread is slightly not tracking with the majority of the tread. If you find even a small ripple, then it is likely the tire causing the issue. Is this one of your new tires? ~CA

You test wheel bearings for play by raising wheel off pavement: grab at 12:00 and 6:00 and try to rock. If loose, you'll know it. Check tie rods by grabbing a 9:00 and 3:00 and rock. Again, if loose you'll know right away.

Can't say I've heard a woosh, woosh bearing, but that doesn't mean it can't be.

Wear sensor rubbing the rotor?

No, new-ish (2 years old) Goodyear Wranglers but not the new-new rears.


Will do the grab and yank test!
Thank you!

New to me.


Last time I did brakes on my car, it was a 1980 Toyota Corolla.

Yeah..most newer pads have built-in wear sensors which is nothing more than a strip of metal that rubs the rotor when the pads wear down. Keeps you from boogering up your rotors. The woosh woosh could be the sensor hitting the warped rotor.

[muckinfuss]

generally the sensor will squeal when it touches the rotor.

Ok - the squeak and squeal I'm familiar with. I'll pull the wheel off soon and take a closer look around, Check the pads.


Thank you!
