Thanks for your input, I will shoot a PM to fritzindian. I did speak with the service technician who was working on my truck and he said he contacted Toyota factory and the regional service manager to get different opinions and they both have not heard of this issue. And their recommendation was to replace the HVAC unit. He also told me he's done a few of these tear downs in the past, for other reasons, on other Tundras with great success...which made me feel a little better.

Though not as extensive, the dealer took apart my dash to replace the clock in my early build 07 Tundra. When they put it back together they included a dash rattle kit, which is nothing more than a generic collection of foam, spacers, etc. to make sure everything looked right and didn't rattle. My truck remained tight and rattle free for 85K miles.
