My Acadia SLT has recently been making a rattling noise when turning left and during acceleration. When Parked if I accelerate the rattling noise also can be heard but diminishes when the engine goes back to normal idle. Noise comes from the front of the engine lower right, just underneath the canister vapor valve. What’s annoying is that there is no service engine light on to indicate a code.
Already replaced the 2 drive shafts thinking it was them going bad. It can’t be a rod failure or the engine would be knocking as soon as it starts. What could it be though??
