The roof opening panel glass brackets are available for service as a kit (FL3Z-1651070-C). Refer to Workshop Manual (WSM), Section 501-17 for diagnosis and repair procedures. Make sure the track is free of debris prior to assembly. For claiming, use causal part 1651070 and applicable labor operations in Section 12 of the Service Labor Time Standards (SLTS) Manual.

SSM 473602018-07-23. Service bulletin. EQUIPMENT:MECHANICAL; EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY. Some 2013-2018 F-150 and 2017-2018 Expedition/Navigator vehicles may exhibit an intermittent grinding noise coming from the right or left IWE area in 2WD mode. This may be caused by an intermittent leak in the check valve. Before completing any normal diagnosis suspect that the check valve is the root cause of the issue. If the check valve has been ruled out as the root cause for the issue refer to Work Shop Manual 308-07 and follow normal diagnosis.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
