I want to avoid taking the car to the dealer at all costs, however I can't seem to figure out where this damn noise is coming from?

Everytime I hit a small bump or big dip in the road, I hear a loud rattle coming from the front drivers side. The noise has been there since I replaced my rotors and lines but lately has become more apparent. It just seems to be getting louder and louder.

I thought maybe the noise was the ss brake line rubbing back and forth through the collar, but not the case. I jacked up the car and had a look see but nothing seemed to be loose.

I did have my car alligned about 2 months ago......not sure if that would have caused anything?

 

Have you checked your heat shields?

 

You might be able to locate the source by jacking up the driver's side until the wheel is off the ground and then smack the tire with a hammer. Don't hit it super hard, just tap it firmly on the bottom and then the sidewall. Anything loose should rattle until you can pinpoint it. A dead blow hammer would probably be better. These have plastic peens filled with sand and won't bounce as much as a regular hammer.
