- Summary
- This article supersedes TSB 20-2028 to update the description of Labor Operation D. Some 2013-2018 F-150/Expedition/Navigator vehicles equipped with 4-wheel drive (4WD) may exhibit an intermittent grinding noise while driving in 2-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 reprogram the transfer case control module (TCCM) and replace any worn vacuum and/or IWE components.
Owners of these vehicles have filed 881 complaints in the acceleration category.
