I have 09 tl shawd.... I hear this noise, sounds like a dangling bar, coming from drivers side wheel. It only happens during low speeds, 20mph or less... While going straight on fairly smooth roads. I had it looked at, nothing was visible and ball joint/tie rods were checked. It was thought to be in the axle, so I replaced it. I can still hear this noise when I take off.
Sorry, I thought I could attach a sound file

 

Could be a loose backing plate (behind rotor) or even something inside your tire. Have you jacked up the front end and given the wheels a good spin?

 

Yes, spun, pulled, pushed the wheels...No noise. What's weird, just had Acura replace the front left axle and noise is still present(sounds like 2 screw drivers banging against each other) but only at low speeds. Will jack up and see if something is loose. I thought about something inside the tire or rim could be the cause. I never hear anything jiggling when I've taken the tires off though.

I'm at a loss

 

It was the tps sensor tumbling inside the tire. SOB.
rolled the tire down the drive, the exact noise appeared. Off to tire store

 

Glad you figured it out but is the TPMS sensor still working??? I would think you would have an error / warning on our dash, no??

 

That's what happened to one of my rear ones. It was clanking in there but the TPMS itself was working. It had a slow leak so it was replaced under warranty but it was broken on the inside and seized up because of corrosion.

 

You're welcome.
