I too have a 2011 and it sounds just like my Mercedes diesel. I'm at 126K, haven't done the tensioners or the TC, but I have had the fuel injectors changed out. I know this isn't directly involved in this thread, but has anyone changed out the engine mounts? I have not. I've put almost 100K on the truck, so not much was done to it in the first 2 1/2 years of ownership.
I've actually thought about replacing the mat on the hood, just to see if that would help deaden the sound a little. Plus, it's been off road and in the water so often, that it's just plain dirty and half falling off.
