Unlike when I tried this when the noise first appeared, I could feel and hear the rumble as I spun the left front wheel. The right front wheel was silent when spun. Despite the fact that the noise has gotten worse and now you can hear it when spinning the tire by hand, the bearing is still tight. No noticeable play in the wheel when I push and pull in all directions.

So I am now going to order the left front hub and new spindle nut from Rock Auto and I will probably replace them early next week (along with the new control arm bushing and stabilizer bar end link).

rotated tires....noise still there.
changed air pressure(added 5 psi) noise got louder
changed LF hub...
NOISE GONE!

thanks folks. seriously....it IS the hub, it WAS the hub, and now the HUB is new.

I ended up writing a HOW TO article about the swap.
it was easier than the thermostat!

Did you change out the hub yet? Noise gone? I am about to do the same thing to mine. Just wanted to know your results.

I have a loud "road noise" on my 06 2LT

I cannot isolate it.
122k
tires have even wear, no OOR issues, drives smooth and straight.
Tires have 18k on them(all 4)

hard to describe, so here goes:
it sounds like when a large 4x4 with knobby tires is next to you.
at freeway speeds around 70 mph it is more pronounced and increases the more distance I drive.
when slowing down to a stop at a signal light(45-0 mph) it sounds like the truck tires as a truck slows.
when at freeway/or any speed over 40 mph if I shift to neutral, noise remains constant and only changes in pitch as car decelerates.
if I shift to neutral and rev engine while at speed, noise remains unchanged.

I suspected a tire issue...as if a tire is under-inflated.
such is not the case

the noise appeared suddenly, not progressively over time.

noise does not change in pitch or volume if wheel is turned/when cornering.

any suggestions?

If your car is 5 years or so in age(you didn't bother to post up that info) then it could be as simple as a battery issue.
Have your local tire shop check it for you.
