There is a TSB regarding this, the TSB is is a quick overview:

2009-2010 Expedition, F-150LINCOLN:
2009-2010 Navigator


Some 2009-2010 F150 vehicles equipped with a 4.6L 3V or 5.4L 3V engine, Expedition and Navigator vehicles may exhibit a low frequency knocking noise from the engine at hot idle only. The noise is predominately heard from the right front wheel well area and/or the right hand (RH) engine cam cover. This noise may be generated from the RH variable camshaft timing (VCT) phaser assembly. This procedure was created to diagnose the RH VCT phaser assembly.

Follow the Service Procedure steps to correct the condition.

The Integrated Diagnostic System (IDS) tests were developed specifically for the vehicles and Power Control Module (PCM) strategies for these vehicles.
Per Workshop Manual (WSM), Powertrain Controls and Emissions Diagnostics (PC/ED) and Scheduled Maintenance Guide, review customer service history for use of any aftermarket oil filters.
