I am trying to figure out what is rattling on my drivers side front on certain bumps or potholes and running out of things to check or replace...I know that sway bar bushings could be worn out but look fine...Mine is a 2012 focus sel with 111, 700 miles on it and the bar bushings look new with no gaps between the bushings and bar that I can see. Have others had to replace there bushings before and at what mileage did they wear out. I know they are inexpsensivve, but they are such a PITA to get to on this car.
