When I first looked at the new 2011 explorer I checked if they had improved the seal on the bottom of the doors to prevent all the road dirt from covering the inside of the door jams, I had a 2002 explorer and it always bothered me how dirty they were. I thought that this problem was addressed on the new model with the hard rubber strip on the bottom edge of the door sill. I bought and installed ford mud flaps to see if this helped. It did a little but not much. I then put on a thin rubber strip over the hard rubber strip where the bottom edge of the door slightly touches to make a better seal. This worked, as I now can drive down dusty roads, wet, slushy salted covered roads and the inside of my door jams stay clean. However I may have not needed to do that. My question is do my doors need to be adjusted? Are the bottom of the doors suppose to be touching the bottom plastic seal? Before I put the gasket on mine there was about 1/16 gap.
