Jack the car up and try to move the wheel left and right by hand. If you can move it get your tie rod end replaced.

hey i just changed my tie rods the vibration is now gone but....still got the hummm i've rotated tires before so i don't think it could be them so im guessing that the only thing it could be is a warpped rotor...the only thing is i don't feel anything through the pedal so i don't knoe....could it still be just a warpped rotor???

if any one has any ideas let me knoe...if it is a rotor im just ganna buy new rims and new brakes....prolly end up doing the corrvette brake swap...i've always wanted to have them!!

Possible wheel bearing?

It's obviously the bearing. Find out what side it is and replace it. Do the same thing the other guy said about tie rod ends but buy a bearing insted. If you can move it the bearing has play and thats why you hear the humming. The wheel movement is from the tire slightly speed wobbling down the road. Let us know how that works out for you.

Def not the brake rotor. That would only cause a vibration in the brake pedal during braking and possibly make the vehicle pull to on side. Jack up the car and start it, put it in gear. If the noise goes away, then its the tires. If the noise is still there, when you turn left and it gets louder then its the right side bearing. Turn left and it gets quiter then its the left side bearing.

A humming sound is usually something that is rotating off balance.

I know this sounds nuts but it could be the power steering pump pulley. There is a weep hole on the bottom of the pump by design. This lets coolant out of the pump right onto the bearing shaft which breaks down the thrust bearings.

I had this same problem a year ago. I replaced the power steering pump itself and the noise went away. Just a thought.

Also, speed increases....RPMs increase.....pulley spins faster....humming gets worse. Have someone rev the engine and see if it is in fact the power steering pump. It may not be but start looking at pulleys on the serpentine belt. Alt, idler pulley, AC Compressor...
