LOWER TRAILING ARM MOUNTING NUT ACCESS HOLE OPENING REPAIR AND/OR REINFORCEMENT
In this procedure any cracks in the frame area around the lower trailing arm flag nut access hole opening will be repaired. A metal blocker baffle
(4W73-4A145-AA) will be inserted into the side rail, and a reinforcement plate (4W73-5A123-AA or 4W73-5A124-M) will be welded to the bottom rail
of the frame to close the access hole to strengthen that section hole.
NOTE
THE BLOCKER BAFFLE WILL PREVENT LEAKAGE OF THE STRUCTURAL FOAM, WHICH WILL BE INTRODUCED INTO THE
FRAME.
