I have the above truck and it has a knocking sound coming from the "B" pillar on the passenger side...its not the seat belts or seats...its emanating from somewhere in the pillar...I have had my local dealer look for it and they heard it, but couldn't find anything....has anyone noticed this in their trucks? I am wondering if it is the side air bag or the belt retract mechanism....? Any thoughts are much appreciated....
