Summary
This article supersedes TSB 19-2252 to update the Parts List and Service Procedure.
Issue: 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.
Action: Follow the Service Procedure steps to correct the condition on vehicles that meet the following
criteria:
• 2013-2018 F-150/Expedition/Navigator
• Equipped with 4WD
• Customer concern of intermittent grinding noise in 2WD mode
NOTE: Part quantity refers to the amount of the service part number required, which may be
different than the number of individual pieces. Service part numbers contain 1 piece unless
otherwise stated.

Service Procedure
1. Is the vehicle a 2017-2018 F-150 or 2018 Expedition/Navigator built on or before 17-Sept-2018?
(1). Yes - reprogram the TCCM using the latest version of the appropriate Ford scan tool. Proceed to
Step 2.
• Note: The new TCCM calibration changes IWE operation at start up. When ambient temperature is above 0°C
(32°F) the IWEs stay engaged regardless of a 4WD mode selection for approximately 0.8 km (0.5 miles). IWE
engagement only occurs once per key cycle and is not reset when shifting between PARK and DRIVE. The
TCCM uses this strategy to delay vacuum use until vacuum-intensive engine startup has completed and
sufficient vacuum is available to fully disengage IWEs.
(2). No - proceed to Step 2.
2. Inspect the IWE vacuum hoses. Refer to Workshop Manual (WSM), Section 308-07A. Are there any
disconnected or damaged vacuum hoses? (Figure 1)
(1). Yes - reconnect or replace the vacuum hose as required. Refer to WSM, Section 308-07A.
(2). No - proceed to Step 3.
Figure 1
3. Replace the vacuum check valve located near the vacuum reservoir. Refer to WSM, Section 308-07A.
4. Disconnect the vacuum line to the IWEs at the vacuum solenoid.
5. Connect a hand vacuum pump to the IWE vacuum supply line and apply 508 mm (20 in) Hg of vacuum.
Does the vacuum drop more than 12.5 mm (0.5 in) Hg per minute? (Figure 2)
(1). Yes - proceed to Step 6.
(2). No - connect the IWE vacuum supply line to the solenoid and proceed to Step 10.
Figure 2
6. Using a hand vacuum pump, apply 508 mm (20 in) Hg of vacuum to each IWE, one at a time, and
monitor the vacuum gauge. Does the vacuum drop more than 12 mm(0.5 in) Hg per minute? (Figure 3)
(1). Yes - proceed to Step 8.
(2). No - proceed to Step 7.
7. Replace the vacuum lines between the solenoid and IWEs. Refer to the WSM, Section 308-07A.
Proceed to Step 12.
8. Remove the IWE assembly from the affected wheel. Refer to WSM, Section 308-07A.
9. Inspect the wheel bearing splines for damage or excessive wear. Is wheel bearing spline damage or
excessive wear present?
(1). Yes - replace the IWE assembly and wheel bearing. Refer to WSM, Section 308-07A and 204-01B.
Proceed to Step 12.
(2). No - replace the IWE assembly. Refer to WSM, Section 308-07A. Proceed to Step 12.
10. Test the IWE vacuum supply lines.
(1). Disconnect the vacuum supply line at the left or right IWE and connect a vacuum gauge to the
supply line as shown in Figure 4.
(2). Start the engine and allow it to idle for 5 minutes to build vacuum.
(3). Connect the appropriate Ford scan tool and enter TCCM data logger.
(4). Active command the vacuum solenoid.
• IDS Vehicles: Command IWE_OS # to No.
• FDRS Vehicles: Command IWE_OUT_ENGAGED = No (False).
(5). Repeat this test on the opposite IWE vacuum supply line.
Figure 4
11. Is the vacuum at both left and right supply lines greater than 254 mm (10 in) Hg?
(1). Yes - proceed to Step 12.
(2). No - replace the vacuum lines between the solenoid and IWEs. Refer to the WSM, Section 30807A. Proceed to Step 12.
12. Road test the vehicle for noise by performing heavy accelerations in 2WD. Engage the 4WD system to
verify proper engagement/disengagement quality. Is a grinding noise present in 2WD mode that is not
present in 4WD mode?
• NOTE: When ambient temperature is above 0°C (32°F) the IWEs stay engaged regardless of a 4WD
mode selection for approximately 0.8 km (0.5 miles).
(1). Yes - proceed to Step 13.
(2). No - repair is complete.
13. Remove the IWE assembly from the affected wheel. Refer to WSM, Section 308-07A.
14. Inspect the wheel bearing splines. Is wheel bearing spline damage present?
(1). Yes - replace the IWE clutch ring and wheel bearing. Refer to WSM, Section 308-07A and 20401B.b.
(2). No - replace the IWE clutch ring. Refer to WSM, Section 308-07A.
