I have a 2001 f150 4x4. There is a noise, like a rotor grind, coming from the front passenger side area. I have changed the both sides; front hub assembly, rotors and pads, both rear axle bearings, rotors and pads, emergency brake drums. The noise occurs worst at 19-20mph when going straight. Could this be the CV axle?


The noise doesn't change when i have it in 4x4, it slightly weakens when i barely touch the brakes or slow below 20mph. I can't get the wheel spinning fast enough on jack stands to make it make the noise.

 

this maybe dumb, but try removing hub caps then drive it. just an idea?? China front hub/bearings units do go bad fast???

 

see if the noise changes driving like a drunk, turning side to side. If it does then its a bearing.
