Front end Rattle

I just purchased this used vehicle last month. There is a rattle in the front end that you can hear pretty much all the time but is very prominent when on uneven pavement or hit a bump. You can feel it in the floorboard. Also, when driving on the highway the car will sway left to right and when veering to the right the car with rock. I have had it to five shops. Everyone can hear the rattle but not pin point where it is. The sway bar links and bushings have been replaced as well as new tires and an alignment. None have solved the issue.
