Does anyone get a rattle on the passenger side when on the highway, 65 mph. This is my second expedition and they both have the rattle. I can't figure out where its is coming from so I can put a stop to it. Itt just seems strange that both vehicles have the same noise near the same location.

 

It may be the large side moulding, or clabbing on the door. Ive seen a lot of people complaining about them flopping, rattling.

 

Inside or outside?

If inside, the door panels are notorious for vibrating and noise at the bottom near the sill.
