Service bulletin SSM 48493
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Some 2019 F-150 vehicles built on 1-Mar-2019 and through 31-Oct-2019 with rear axle tag code S-971-M may exhibit a clicking/ticking noise from the left rear of the vehicle while driving at low speeds. The click/ticking noise from the left rear axle wheel end may be caused by a wheel bearing bore surface that is not machined. If no metal contamination is present in the fluid, inspect the left side rear axle bearing bore for an unmachined surface in the 12:00 oclock to 3:00 oclock position. If an unmachined surface is found, replace the rear axle housing.
