Dieselfreak, I read the post, and overlooked the Roush CAI part. Only reason I asked is because after I installed my Roush CAI, I started getting a humming/vibration in my truck and I can feel it in my gas pedal as well. Another thing you can try atnolan is when the humming starts at 50+, shift your truck into neutral and see if it stops. This can help eliminate it being in the driveline.

Well,while thinking about the issue today, I really think that my frame damage has compromised my motor mounts. While they aren't broken, I don't think they sit flush like they're supposed to. Me and my buddy are going to spend the whole day tomorrow trying to figure it out.

How are your sway bar ends. Mine went bad and even tho the truck was aligned it cupped the outside of the front tires and gave me a vibration from 45-55.

Great idea! my buddy had the same idea. I checked them two weeks ago when I did my struts and they were good. Still doesn't explain the low speed hum too.

As an update, this morning was about 40 degrees here in beautiful Stillwater Oklahoma. I started my truck and backed out the driveway so the truck was still cold. the second I hit the gas it hummed as bad as it would on the highway at under 5 mph.
