Service Procedure
Review the following video before ordering parts or attempting to repair a vehicle:
Video Link – Super Duty Underbody Insulators Loose/Sagging
NOTE: The underbody insulator is located directly above the exhaust. The insulator is highlighted for illustration purposes only in Figures 1-2.
Figure 1 – Crew Cab
Figure 2 – Super Cab
1. With the vehicle in neutral (N), position the vehicle on a hoist. Refer to Workshop Manual (WSM), Section 100-02.
2. Measure and mark the locations on the underbody insulator according to cab and wheelbase:
(1). For Crew Cab vehicles with a 160 or 179 in. wheelbase, refer to Figure 3.
(2). For Crew Cab vehicles with a 175 in. wheelbase, refer to Figure 4.
(3). For Super Cab vehicles with a 164 in. wheelbase, refer to Figure 5.
(4). For Super Cab vehicles with a 192 in. wheelbase, refer to Figure 6.
Figure 3
Figure 4
Figure 5
Figure 6
3. For rivet part number W719880-S417, use the 5.1 mm (13/64 in) drill bit. For all other rivets, use a 6.7 mm (17/64 in) drill bit to drill a hole through the insulator and into the floor. (Figure 7)
(1). For Super Cab vehicles with a 192 in. wheelbase, lay the washer on the flat surface and follow the dimensions as shown for the pilot hole center. Refer to Figure 8 where the yellow line is the washer and the blue line is the rivet.
(2). Use the 13 mm (1/2 in) drill stop to make sure the drill bit does not reach the carpet.
Figure 7
Figure 8 – Yellow line indicates the washer, blue line indicates the rivet
4. Using a small brush, apply a layer of Motorcraft® Anti-Corrosion Coating to the edges of the newly drilled holes.
5. Install the washer onto the rivet. (Figure 9)
NOTE: Not all approved rivets may appear the same as shown in these instructions.
Figure 9
6. Apply a thick layer of Motorcraft® Seam Sealer (Black) to the rivet and the backside of the washer. (Figure 10)
Figure 10
7. Using a 1/4″ rivet gun, install the rivet and washer to the drilled hole. (Figure 11)
(1). To confirm the rivet is properly secured, apply as much force to the rivet gun as possible.
Figure 11
8. Attempt to move the washer/rivet to confirm it is properly secured.
9. Using a small brush, apply a layer of the Motorcraft® Anti-Corrosion Coating to the washer and rivet.
10. If a second drilled hole is required, repeat Steps 3-9.
