Here is a SSM that was used for my rattle...

There is also a TSB about the problem. (#03-23-03 -- 2003 EXPEDITION/NAVIGATOR: BODY - TRIM -
NOISE FROM DOOR CLADDING)

17078 2003 EXPEDITION/NAVIGATOR - RATTLE, RUBBING OR
TICKING NOISE FROM DOOR
SOME 2003 EXPEDITIONS/NAVIGATORS BUILT BEFORE 7/21/03
MAY EXHIBIT A RATTLE, RUBBING OR TICKING NOISE FROM
ONE OR MORE DOORS DUE TO EXCESS MOVEMENT OF THE DOOR
RELATIVE TO THE LATCH STRIKER PLATE. TO VERIFY, DRIVE
VEHICLE AND MANUALLY PULL DOOR INBOARD WHILE NOISE IS
PRESENT. IF NOISE IS UNCHANGED, CLADDING RATTLE IS A
MORE LIKELY CAUSE. IF NOISE DECREASES, REPLACE

DOOR(S) AS NEEDED BASED ON BUILD DATE: UNITS BLT AFTER
05/12/03 CONTAIN REVISED WEATHERSTRIP; UNITS BLT AFTER
