Just wanted to give an update in case someone else ever hears this sound.

Last night I checked the torque on the 6 H-bracket bolt and they were all fine, which doesn't surprise me because I didnt think that was the problem. While working on my car, I decided to lube the front and rear sway bar bushings as well.

Today I went over the same speed bump twice, and the car was completely silent. Last time I went over the bump it was 32f outside, and today it was 48f outside. My guess is lubricating the sway bar bushings did the job, since I don't think a 16f temperature difference could make the sound go away completely. Ill see if the sound comes back some night when it's colder out, but I don't think it will.
