2007 Tahoe - Rattle Driver Side
 

I have an LT 07 Tahoe. I am experiencing a rattle that sounds like some time or rubber/plastic flapping against metal at speeds from 55MPH on Up. The rattle/flapping sounds like it's coming from the driver sides wheel well. I've looked and looked and I can not see anything that feels or looks loose.

I wondered if anyone knew of a TSB for this and/or is experiencing a similar noise issue.

Thanks !
