Seems to be a intermittent creaking or rubbing sound from the door area on driver's side. More pronounced when braking, turning, bumps, etc. Any way to isolate this? Is this a common problem. Does not seem to be from the lack of comments on here...other than the door noise dampening material that can be added. I thought it might come from the latch area, but everything seems tight there, well lubricated. Only occurs on the driver's side.
