I have an 05 FX35 that i have had for about 3 weeks purchased brand new. Well ever since I have had it, there is an odd squeak or rubbing noise coming from behind the drivers seat when i go over a bumb of just about any size even a small one. I know it is coming from somehwere around where the seat belt is attached to the pillar on the drivers side. Has anyone else had this problem? What could it be? Any suggestions? Can i fix it myself?
