Default Humming in my LGT

I have had an odd humming in my 06 LGT recently and the last few days it has gotten worse. Its a very consistent humm that gets a little louder the faster I go. (no humm at idle)
I've wondered if its a bearing or something worse. Any ideas???

Wheel bearing. Try weaving back and forth as you drive down the road - does the sound change?

Tire. Check the air in all your tires - is one of them low? Rotate the tires - does the sound change location?

All good points to check in accurately diagnosing the root cause of the problem

i had this same problem, drove me nuts.

90% likely to be bearings. there was a recall for them to be replaced gratis, but it may've expired.

tires could be contributing. as most tires wear out, they get louder. this really shouldnt be noticeable under 40mph.

other rare possible causes:
- diff oil needs change
- rock or pebble stuck between backside of brake disc and the metal dust shield that sits inside the wheel
