when i'm driving at night and i go over a bump my headlight shakes. i couldn't find anything that seems to be loose, but it will move up and down whenever i put a little bit of pressure on it. is there anything that can be done to stop this?
there are screws that adjust the headlight up/down left/right
they are revers torx bits.
Sometime when these are loose they will cause the headlamp to bounce all crazy..
Also have you ever removed the headlamp? If you have ytou need to make sure you put in back in correctly.
There is a plastic tab on the inside part of the housing that slides into a metal frame of the body and also on the outer edge of the headlamp housing there is a black clip this will also grab on to the metal of the car . I has an instance where the plastic tab that holds the headlamp unit in place snapped in that particular area this caused the heamlamps to bounce..
