Really? You are only getting this knocking sound when you are idling in drive? It is more apparent on my passenger side. Sounds more like something is wrong then giving the best of the engine sound.



Heard it might be serpentine belt being loose but checked it also and its sturdy and slack or twist to it. Will have to find time to stop by a shop to just double check for a peace of mind.
