ok so ive had this car for a few months now and the front end is very boucy. i brought it to a dealer and they say there is nothing wrong with my struts they are fine. i dont know much about cars so im in a bind. like the front end bobs up and down and when im driving down the highway at night my headlights go up and down because my front end is bobbing. i dont think this is normal. any suggestions? its worse on roads with the sectioned cement. any other people have these issues? what could this be? i did have my intermediate shaft regreased when i first got it due to a rubbing sound when turning.
