this is on a jeep you drive and turn the wheel to make a turn down the street and there is a grinding on and off. sounds like if the rotor would be warped now this only happens when you turn so that pushes me away from a warped rotor because wouldn't it grind on and off all the time? If you guys can think of anything please write back. thanks

 

Wheel bearing?

 

you think that could be it? only when you make a turn down a street
how much of a pain is it to change one of those

 

How hard are you cornering? If the body is leaning enough, there will be more weight on the bearing. I have no idea what's involved in a wheel bearing replacement for a Jeep.

 

soft cornering say if you are turning out of you drive way then it will start with the noise.
