Some 2003-2020 Expedition/Navigator and 2006-2020 F-150 (non-Raptor) vehicles equipped with 4WD may exhibit grinding/clicking/ratcheting noise from the front wheel area. This may be due to partial engagement of the integrated wheel ends (IWE). To correct this condition, follow the Service Procedure to remove and cap the vacuum supply line or to reprogram the transfer case control module (TCCM) and replace any worn vacuum and/or IWE components.

When does it fail?
Of the 7 powertrain complaints filed for the 2014 Lincoln Navigator, here's the actual mileage breakdown — failures cluster heaviest at 75,000-100,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
No new NHTSA powertrain complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Some 2013-2018 F-150/Expedition/Navigator vehicles equipped with four wheel drive (4WD) may exhibit an intermittent grinding noise while driving in two wheel drive (2WD) mode most commonly on acceleration. This may be due to a loss of vacuum to the integrated wheel end (IWE) actuators and/or wear of the IWE components. To correct the condition, follow the Service Procedure steps to replace the worn vacuum and/or IWE components.
full bulletin at NHTSA ↗On vehicles equipped with an automatic transmission it is imperative that the converter pilot hub be greased with Motorcraft Multi-Purpose Grease Spray XL-5-A even if grease was not applied from the factory. Also verify that the engine/transmission alignment dowel pins are present as well as the engine crankshaft dowel pin, if equipped, when installing the transmission. Failure to adequately lubricate the converter hub greatly increases the likelihood of the flexplate cracking in the future. Missing dowels may cause a misalignment issue also resulting in a premature failure. Refer to Workshop Manual (WSM), Section 307-01.
