+1 this worked for me! I just bought a 2014 Silverado and I had a terrible rattle coming from under the steering wheel. I took this panel off. 3 of the 4 bolts were very loose and the 4th one fell out onto the floorboard. I also added a little strip of rubber and washer between the metal shield and the torx screw. Rattle is completely gone!
