Continued to research online, and discovered that there's an IWE vacuum check valve that is prone to failure. When this part fails, vacuum pressure is lost and the system starts slipping from 2wd into 4wd on the front 2 wheels ...When you're checking voltage to the solenoid, use the pigtail for your test connections. When solenoid is energized, you should show 12v +/-. when deenergized, you'll still show some voltage, 3v +/-, or so. If you get no change of readings, your TCCM is suspect. If readings do change, the solenoid would be the trouble.IWE or Check Valve. 2016 F-150 with eco boost. Got a lot of good info here for troubleshooting the grinding sound cause by the IWE.

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.The second check valve located right before the IWE solenoid holds the highest vacuum to the actuators from what has been exerted from the engine. As you start to understand the vacuum system and series of check valves, you will see that the vacuum box that is located between the two check valves does in fact act as a reserve.2015 - 2020 Ford F150 - IWE Vacuum Test - Purchased a super reliable vacuum gauge from HF, and got some interesting results that seemed to clash with what I saw on the forum. ... 4H, or 4L, that little valve falls downward with spring assist, closing the vacuum supply port, and opening the vent port, venting the vacuum to atmosphere, therefore ...2019 with 2300 miles and a bad 4x4 actuator solenoid. No noticeable symptoms but was unable to have an on car tire balance due to locked hubs. if you're un familiar with the system, it uses vacuum to disengage the auto hubs. The system defaults to 4x4 locked hubs without vacuum. This is to ensure 4x4 works in a bad situation, however if the ...
The purpose in life of the check valve is to hold vacuum -vacuum is pulled to the IWE system. It requires 15 inches minimum to operate. With higher RPM, vacuum is reduced. So the check valve will hold the highest achieved vacuum to the IWE system.2019 F-150/Expedition/Navigator vehicles equipped with four-wheel drive (4WD) have a revised transfer case control module (TCCM) strategy that will affect integrated wheel end (IWE) operation after initial start up. The TCCM will not energize the solenoid to supply vacuum to the IWEs after the initial key cycle and a driven gear is selected.I replaced the IWE actuator on this Ford F-150 truck because it was grinding. This is a common problem but it is an easy fix.Genuine Ford IWE Actuator ... ….

To better understand the functionality of the IWE system in the Ford F150, it is helpful to refer to a vacuum lines diagram. This diagram illustrates the various components of the system and the vacuum lines that connect them. The diagram typically shows the IWE solenoid, which is responsible for controlling the vacuum supply to the actuators.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.When shifted to 4x4, solenoid opens so vacuum is drawn at the IWE (unlocking the hubs). Because vacuum rate is varied, a check valve is next in line after the solenoid. A check valve allows air (in the case) to pass only in one direction. The check valve prevents vacuum loss as manifold pressure is reduced.
