For the uninitiated, Ford’s Integrated Wheel End (IWE) system is what locks and unlocks the front hubs when you change back and forth from 2WD and 4WD.
In regards to, how do I check my Ford IWE?
Furthermore, how does Ford IWE work? The IWE actuators are also referred to as Constant Vacuum Hub lock (CVH) actuators. This design was first introduced in 2004 applications and worked opposite of the earlier Ford design CVH actuators. For this design, the vacuum is placed on the system unlocking the hubs while the truck runs in 2-wheel drive mode.
Additionally, what is IWE? idiom. —used to say that one does not know the answer to a question and is surprised to have been asked it.
Likewise, what is a IWE check valve? The IWE check valve is a vacuum system that engages and disengages the front wheel hubs; if Your check valve fails, the vacuum fails to hold and the front wheel hubs will attempt to engage on their own.

How do you test an IWE solenoid?
How much does it cost to replace a hub actuator?
Labor costs are estimated between $96 and $121 while parts are priced between $380 and $409.
How does F150 actuator work?
The actuator on the Ford F150 connects the wheel hub to the axle shaft when the 4WD mode is selected. More precisely, it disconnects the hub and the axle when the 4WD mode is not engaged, reducing driveline loss caused by spinning an otherwise non-rotating axle.
How do vacuum locking hubs work?
The locking mechanism inside an automatic locking hub is sort of like a one-way clutch. When torque is applied by the driveshaft, it forces the hub to slide in and lock. The hub then remains in the locked position as long as the transfer case remains in four-wheel drive.
How do you test a hub actuator?
How do you test a 4×4 solenoid?
What does vacuum actuator do?
A vacuum actuator is a mechanism that supplies a switching or activation force to a secondary device via the vacuum-induced movement of an internal piston or diaphragm. These actuators are typically found on machinery or processes that produce vacuums during operation, such as automobile engines.
What is a hub actuator?
The hub actuators connect the axle shaft to the wheel hub automatically when 4WD is selected. More accurately, they disconnect the axle and hub when the 4WD system is not engaged, reducing driveline loss caused by spinning an otherwise non-rotating axle.
How long do wheel bearings last f150?
Sealed bearings can last 100,000 miles or more, and will need to be replaced once they go bad. Vehicles with traditional, tapered wheel bearings should have them serviced every 25,000 to 30,000 miles — replacement may not be necessary as long as they’re maintained.
How much does it cost to replace a vacuum actuator?
The average cost for door lock actuator replacement is between $290 and $332. Labor costs are estimated between $89 and $112 while parts are priced between $202 and $220.
How do I fix my f150 IWE?
Should I keep my hubs locked?
Why does Ford have locking hubs?
So that way you can easily switch between 2 and 4 wheel drive without getting in and out of the truck. Having vehicles with supposedly automatic hubs, The manual ability garantees the front axle is connected to the spindles. Then all you need to worry about is that the transfer case is engaging the front axle.
How do I know if my car has locking hubs?
How do you know if your IWE solenoid is bad?
Pump the pump up and see if the vacuum on the guage holds. If it does not and leaks down, you have a leak in your lines between the solenoid and the actuators. Check the lines very thoroghly from the solenoid to the wheels, its hard to get to some of the lines, but they all need checked, look for cracks or breaks.
Where is the vacuum actuator located?
A vacuum actuator is attached to the ‘gas’ pedal and is connected to the throttle valve via a cable. A signal from the cruise control computer causes the throttle to engage or disengage.
How do I know if my 4WD is working?
Get in an open area and drive the truck around in a tight circle. With the 4×4 on, you will be able to hear the front wheels “fighting” you when you cut the wheels. It will be like a clunking sound. If you do not hear this while in 4wheeldrive, it isn’t working.
Is the actuator vacuum controlled?
A vacuum actuator has a chamber that it uses to create vacuum pressure. As air leaves the actuator, a vacuum is created, which causes outside pressure to act on the diaphragm of the actuator. The pressure then overtakes the spring inside the actuator and allows it to open.
What are the three types of actuators?
- Linear Actuators. Implied by their name, linear actuators are devices that produce movement within a straight path.
- Rotary Actuators.
- Hydraulic Actuators.
- Pneumatic Actuators.
- Electric Actuators.
- Thermal and Magnetic Actuators.
- Mechanical Actuators.
- Supercoiled Polymer Actuators.
How does vacuum operated cruise control work?
Many cars use actuators powered by engine vacuum to open and close the throttle. These systems use a small, electronically-controlled valve to regulate the vacuum in a diaphragm. This works in a similar way to the brake booster, which provides power to your brake system.
