After my friend helped me to change the battery on my car, he accidentially dropped the no.10 socket down to the engine bay near where the battery located. On the other day, when I went to speed bump and got out of the car, there was some weird sounds coming from the frontleft fender. After that, I brought my car to the shop and let the mechanic to take alook at my car. He said that the sound is most likely the bushing from the front sway bar. It's so annoying to me whenever I get in and get out of my car... Anyone know how I can fix it? or anyone had the same problem on your TL before?
Thank you for the help

 

does it do it only when moving? Only when hitting bumps? Is it the socket rattling? need to get a better diagnosis.
