Does it do it at idle? If it does maybe remove the fan belt to see if that eliminates it. Maybe it's the idler pully. The timing chain issue doesn't stop and does fluctuate with the engine speed.

Before you take off the serpentine belt I would just take the truck into the dealer and ask them to check and see if it is the time chain guides. I just did this the other day on my 2007 SE and they were able to tell me I needed new guides and a new chain in about five minutes with the truck. It didn't cost me anything to have them check it and since my truck is under 60,000 miles they are going to warranty the fix. Good luck.. If you feel like it maybe the serpentine belt you could take it off and it isn't really too hard to do, just takes some time.Thanks so much for the advice. I honestly don't know (or want to know) how to remove a serpentine belt so I was just looking for some good advice to listen for when they give me their diagnosis.
Thanks again, guys!!
Some dealers will threaten you with a one hour labor charge if it's not a covered item. So it's free under the 5/60 if it's the chains but if it's something else like pump or alternator and not covered you're either out that money or have to have them perform the repair.Before you take off the serpentine belt I would just take the truck into the dealer and ask them to check and see if it is the time chain guides.
