I am hearing a popping noise on the back right side of my G35 Coupe. Its like a rock is hitting my car from underneath. Any ideas what it could be?

 

get under there and look for something loose (suspension, exhaust maybe), is it happening when you go over bumps, or when you turn, or all the time?

 

There is a good chance maybe the rear sway bar is loose.

 

i've been getting that same noise ever since i put on my coilovers. what part of the sway bar should i tighten (pics)?? i've searched and have come across sooooooo many people with this pop/clunk noise from the rear passanger side. coincidence? maybe not.

 

any updates??
