1998 Pontiac Sunfire grinding noise

I have a grinding noise coming from the driver side engine bay. It just had a driver side cv axle changed, I didn't do it. Manual tranny, gt model. The noise only happens on deceleration, when I'm on the gas the noise completely goes away. It sounds like something like metal scrapin. I checked the cv axle installation, looks all good. Checked tranny fluid, all is good. Any ideas would help, this might be easy for a mechanic to answer seeing that it only happens on decelerating, but I have never encountered this. Thanks!
