New FX4 owner!
Hi All,
I just picked up my new 2011 FX4 Screw 5.0 last month. It is black with black leather, NAV and moonroof. I love this truck! I do have a question, I hear a slight knocking noise when truck is fully warmed up. I only hear it when in reverse or drive at low speed. When truck is in neutral and I rev engine slightly, it sounds smooth, no knocking. But put in gear and back up or pull up slow and I hear it. Not real bad, but sound is there. Kinda odd that I dont hear anything when its in park. Is this normal? I have searched the forum and see a TSB, but my truck was built in Sept of 2011.
Thanks for your help.

Congrats on the new truck! Lets see some pics already.
On the noise, I would drive it for a bit and see if it gets any worse/more noticeable. Sounds like a charactoristic of the 5.0 from what I have seen.
