New rear, same clicking or popping when I take off in forward or reverse. It will click(pop) one to three times when I first start rolling, sometimes when I shift into gear it will make the sound once. 07 titan king cab XE. Is more frequently in reverse. it is not the wheels. It is not the typical Titan clunk. This is a higher pitched click. Please help. Dealer can't fix. I have requested an engineer from Nissan, still waiting on a response.
