[V8FunNaturally]

I've read this thread because I heard some very light metallic pinging noise today like someone throwing a small pebble at a large empty can 5 times from the back of the car while taking a slow sharp right turn right after being stopped at a red light. This is a completely bone stock new car that was just serviced for the 1200 miles service. This occurred twice today and never before. I am a conservative and careful driver. I have never driven the car hardcore, never floored the throttle, never red lined it, and never done any launch. Do not even try that angle of question because this car was broken in as per the book and I just progressively started to do more sporty drives, nothing radical. What could this be ?? Is this thread relevant to the noise I am hearing ?

I first thought i needed the alternative differential fluid but upon checking the part # they used 2282583 Final-drive gear oil SAF-XJ which is the alternative one already, not the original 83-22-1-467-993 one.
