Clanking sound

#1

My 2006 tundra has a clanking sound under the front end. I took it to toyota and they thought it was a heat sheild but the clank is still there. At low speed and starting and stoping its like some one droped a metal ball and it bounces.

Socket or some other object that fell into some channel while it was being serviced, maybe?
