I have a strange hum comming from the front passenger wheel of my truck i thought it was the wheel so i switched the 2 front tires and it wasnt the wheel so i am wondering what that noise is. does anyone else have this noise or knows what this noise might possibly be i hope it isnt my front axle or something b/c i dont have the money to fix it to begin with lol so somebody plz. help!! lol

 

anything in the brakes? does it come and go away when you brake? does it get louder when you turn left or right? Could be a wheel bearing, help diagnose that by turning fairly hard left and right, listen to the sound. If you turn right and it gets louder, its your right side...vise versa for the other.

 

More info will be needed. Like what Mike suggested, plus does it vary pitch with speed? Does it do it all the time, or only at a specific speed?
etc...

 

the sound goes away when i turn the wheel to the right and it and i think it might get louder when i turn the wheel to the left but im not quite sure ill have to drive it once more

 

it doesnt seem to change when i turn the wheel to the left but when i turn it to the right it goes away

 

it makes the noise the loudest right around 35-40 mph but whenever your driving you can hear it but that is when its the worst

 

jack up that side and spin the wheel, if it howls wheel bearing
