I have ground control's in my 5th gen lude and they have been squeeky before, and the noise went away. But now I am hearing a very loud sound coming from it sounds like the middle toward the rear of the car on the passenger side. It sounds like metal clunking together. If its not my suspension wtf could it be??? I also have the N1 and my car is pretty low so it scrapes alot, could the sound be something to do with the exhuast? Thanks

 

Jack up the car ( don't forget to use jack stands ) and check out the under carriage and suspension for anything loose.
