I recently noticed have a slight humming noise from my front tires.
I just replaced the Kframe last year around this time with an 04 k frame, i have to replace my rack and pinioin here soon (it kinda clicks a little.) because when we took it off the old one i think we damaged it as it was kinda rusted to the old one...
now im thinking could the humming noise be from just the tires (they are a little worn, but not terible)? or do you think it could be control arm or a brace (idk what its called) bushing goign out? it not anything in the motor and it doesnt go away or get quieter when i turn the steering.
click sig for my car audio videos
could also be a wheel bearing, i know at the start when they start to humm they can sound like worn tire, but after a while the sound is very different.
I'd check your alignment. Mine's humming at the moment and I KNOW my toe is WAYYY out of whack.
Still not low enough for a signature.
Check your tires too, make sure they aren't cupped or really worn down, Ran into an issue with some bad tires that duplicated the same humming noise, and they weren't balanced right either.
