I was hearing a faint rattling noise coming from underneath my car. Brought it somewhere and they put it on a lift and the problem was little pebbles rattling from underneath, inside of a plated area. He was able to get some out but not all of them. Im going to go back next week for an oil change and to get the rest of them out but just wanted to see if anyone else had it was was able to get it out themselves. I doesn't effect the drive or anything but the sound is just annoying.
I don't know car parts that well so I don't know the name of the area where they are. I also couldnt find any pictures of underneath to circle where im talking about. I directly in the middle of the width of the car and goes from infront of the exhaust to the underneath the engine. I think it might be the drivetrain?

 

I dont have that issue, and honestly, never heard of such a thing
