Check the bad vibration and tire noise thread in this forum.

They have road force balanced the tires I believe 3 times now. That's how they found that two of them were out of spec and those were replaced. I'm going to attempt to climb under the car tonight to check the bolts on the driveshaft to see if they're loose. I'll see if I see any weights on there as well. I had checked the other thread as well but I'm so far avoiding any tire noise. Oh and they've done an alignment and turned the rotors as well. GM stepped in to help figure it out so we'll see.
I was going to put on a CAI intake this weekend too but I'm now thinking otherwise until this issue is fixed as I don't want them trying to come up with some dumb excuse as to why my car is acting up...
I'm sure it will get solved eventually but it sucks right now. Just gotta keep being optimistic...
