Acceleration noise....
First off, Im new to this world and I must say its the best.
I have a 2002 f150 V8 5.4 automatic fx4 truck with 149,000 miles.

My truck makes a grinding or screeching noise when i accelerate. But when i let off the gas it goes away and then comes back when i accelerate again. It doesnt make noises when i accelerate in park. So it only does it when the wheels are turning. What could the problem be? Thanks

 

see if a moderator will move this to the powertrain section.

 

Power sterring pump bearing, maybe a belt??

 

thanks for the guidence
