Odd noise when braking

[rbf351]

Wanted to see if anyone else has this odd noise which I can only explain as a groaning/whirring sound when braking.

Started to happen months ago, so i thought it was possibly pads/rotors. Replaced them last week, and still have the noise, so I can rule those out.

Here is a video I took earlier, the noise is faint, but it is there. hopefully you can hear it, and someone else has had this issue, and can explain it

Will try to get a better video if I can

dont really hear too much. if anything it sounds like the tire is low on air or out of balance and giving a rumble on braking.

perfectly balanced, and air pressure is exact. tires are fairly new as well

tires can cause that, even new ones. are they the same kind as your previous tires?
i'd also check control arm bushings.

same brand tires, but they are new.

Haven't checked the control arms yet

here are 2 more video where you can hear it much clearer

this is from my dashcam

this is from my phone

looking as if it's the wheel bearing.

Have one on order, and will be replacing it

looking as if it's the wheel bearing.

One way to confirm this, if you haven't already, is to pitch weight onto each corner. Increasing under braking obviously points to the front, and if you pitch the car into a long sweeping turn you can load up the left or right and see if the noise increases/decreases. The back is a little harder because your engine noise may drown it out (trying to accelerate), but loading up one front corner should unload the opposite rear.

You can also jack the suspected corner up and spin that wheel by hand to check resistance, but wheel bearings are pretty hearty and unless it's really mangled it may not be obvious without the car's weight on it.

I've done those tests which is all pointing to the front passenger bearing. I also hit a nasty pot hole(lovely NYC daily driving) which cracked that rim. So it does make sense

finally found someone else with the same noise, but they sold the car instead of fixing it.

anyone have any idea?
