When I driver between 10-20 mph while coasting to a stop, there is a rattling/knocking coming from the left front end. I have jacked the front end up and shook the wheel and axle and nothing seems to be loose. What could be making this noise.
Don’t rule out front struts and/or strut mounting and cushion components. I see where the manufacturer says to replace any 07-09 Patriots front jounce bumper/dust shield parts if the car came with one piece black rubber jounce bumper/dust shield when replacing struts. So, apparently these have been redesigned to a 2-piece assembly. It makes we wonder what part was failing.
Also, check brake calipers and hardware.
