Anyone have idea what this could be? I hear a hum/whirling noise when I drive, I can hear it the most up to 40mph and all the way down to stoping. i think it's the bearings because I just put new tires on less then 1k miles (nitto 555- 35series) on 19" works. Here are other things i noticed. when I slow down to less then 5mph, the car jerks/bounces real slightly. I also just installed bc coils same time as tires. Any ideas?

i'd check alignment rather than wheel bearings. i know i just installed coils and it was kind of loud until i got an alignment. toe was very off.

Do you have aftermarket wheels? If so, one of your hubcentric rings may have come off without you noticing. It could be a torque issue with the lugnuts. It also could be a wheel/tire that is out of balance.

If it is a wheel bearing that is not as bad as it may seem. The wheel bearing and the complete hub unbolt and rebolt as a entire assembly.

I have work vs-xx and I don't have hub rings. Does anyone know the hub ring size for works?

I had a similar problem with my IS, from 30mph and up I would hear the hum sound you might be referring to. For me it was the wheel bearing after I installed my coilovers...

You will have to measure. Take a ruler or tape measure and measure the opening for the hub. If you happen to have a caliper that would be better. Make sure you use mm

If its a bearing then it will be almost a pulsating sound, on and off. If you suspect it's just one side try turning in that direction and away from it and take note of the sound. If it gets worse its the opposite side of the side you're turning towards if that makes any sense. Usually they don't go bad too quickly unless there was some sort of impact.

Was that humming/ whirling noise present before you got new tires? If not, id be willing to bet that you got some A) Defective tires or B) Shi tty tires.

As for the jerk/ bounce of the suspension, id go double check to make sure all bolts are tight

Did you replace all bearings?
Yeah, I'm gonna try to put the stocks back on and see if I get the same thing.
