I have noticed every time i go over a rough part in the road my passenger seat shakes and i can hear it, it sounds horrible. Only when someone isnt setting in it. I have a 2004 fx4 with console shift and leather interior. I can shake the back rest but it barely moves, just enough to make noises and annoy me. Any one have this problem and what can i tighten down. I looked under if but all the bolts seem impossible to get to.
Thanks
