03 6.0L Noise While Turning

[maxgrafex]

New owner of an 03 F250 6.0L 4x4. Love it so far. Just replaced passenger front bearing via mechanic advise. Problem I'm having is when I turn left AND apply the gas pedal, I hear a grinding noise and get some vibration. I'm not in 4x4, and the wheels don't hit the fender well (thought they might be but took the fender well out and it still made the noise). Let off on the pedal and noise and vibration goes away. Only happens on a left turn. Doesn't have to be a tight turn either. U-joints seem tight. No noise on right turn or straight, with or without pedal depressed. Noise is louder at higher speeds. Is this the driver front bearing? Doesn't make any noise when I lift up the wheel and turn it. Any suggestions would be appreciated.

Are u sure the noise is comin from the front? My truck was doin kinda the same thing, ended up needing some additive for the posi clutches in the rear end.

Yes, sounds like it's coming from the front, but thanks for the suggestion. I might try that too.

OK, figured out the noise. It was the exhaust. My truck has an aftermarket exhaust and when turning left the torque of the engine caused the exhaust to touch the frame - thus the "grinding" and vibration. When letting off the pedal, the sound went away because the torque was lessened. A little prying and readjusting of a clamp and there you go... no noise.
