Can somebody tell me if my front wheel bearings are shot? Have vibrations in my car at all speeds crusing along the road. Here is the video of both sides left and right. The left side has sort of a slight whining sound.

It’s hard to tell for sure, but the noise from your left wheel sounds like the brake pad just skimming the surface of the caliper...

If you spin the wheel while grabbing a control arm or something else attached to the hub, can you feel a vibration that coincides with the wheel’s rotation?

Generally a wheel bearing failure will not cause vibration. If a wheel bearing fail is so bad that it causes vibration you can check that by grabbing the tire at 12-6 position and tug it should have no play. Same with 9-3 position. If it has play bearing is shot but it still should not cause vibration.

Your interior vibration is most likely control arms. Thats if you feel vibration when car is in neutral too. Otherwise could be drive train related.

Just to add another check, if a bearing is bad, when you spin the tire you will feel a little more resistance and it will spin tight as if the brake is being applied. The tire should spin freely when no brakes (Emergency / Parking brake) are applied. As far as sound goes, the noise you will hear is a "whoomp whoomp whoomp" like a helicopter that speeds up or slows when you accelerate or decelerate or come to a stop. This happened on a previous car (2003 350Z) I used to own.

Already done control arms.

A wheel bearing doesnt cause vibrations? Not sure why they wouldn't. Also the wheel bearing sometimes won't have play all the time if it's bad.

Looks like you know all your issues then goodday

Just curious to know your theory on how wheel bearings wouldn't cause vibrations is all!

see I tried this with the spring.. Absolutely no vibration in the spring when spinning the wheels, but, if I shake the wheel forward and back slightly both sides there is a slight clunk feeling in the springs. Not sure if this is normal?
