What is an IWE on a Ford F150? The IWE system locks and unlocks hubs to switch from 2WD to 4WD. Ford 4WD drive systems are designed for moderate off-road use and have a manual or automatic transfer gearbox. They also typically have higher ground clearance. A few more expensive SUVs have height-adjustable suspension. In addition, 4WD vehicles are typically capable of climbing slopes and moving over obstacles.
The first step in determining if an IWE is malfunctioning is to check the vacuum in the IWE actuator. You can check this by inserting a vacuum hose into the second hose that feeds the IWEs. If it is working properly, then your front wheels will spin freely. Some earlier models of the F150 had issues with the transfer case shift motor, but they have improved since 2004.
A failing IWE may be a sign of a problem. The IWE system locks the front hubs when shifting into 2WD mode. However, if the vacuum is leaking, the front wheel hubs may engage on their own. In this case, it may be worth contacting a mechanic to have it repaired. In addition to replacing the IWE, your Ford F150 might also need a new exhaust system.

How Do I Know If My F150 is IWE?
If your Ford F150 has an IWE system, you may be experiencing grinding or screeching sounds. The IWE system is a part of your truck’s drivetrain that allows the front wheels to turn freely. You can test the IWE system by sticking a vacuum hose into the second hose feeding the IWEs. If it is working properly, you should be able to rotate the front wheels with ease.
Several problems can cause this symptom. The vehicle may show an error code, such as C1979, which indicates that the solenoid is bad. This error code is caused by a number of things, including a blown-out or open harness, a faulty electrical connection, or poor connection. In order to properly diagnose the problem, your vehicle needs to be inspected physically. If there is physical damage, other repairs may not be possible.
An IWE check valve prevents the front wheels from engaging automatically when switching drives. If this check valve is faulty, the front wheels may engage on their own. To fix this problem, take your vehicle to a service station. Unless you’re comfortable working on your vehicle yourself, it’s probably best to hire a professional. The service station will be able to diagnose and repair the problem for you.
What is an IWE Hub?
You’ve probably seen a Ford F150 with an IWE hub, but you may be wondering, “What is an IWE Hub?” The IWE system is the name given to Ford’s locking hub system. These hubs are vacuum operated and function as locking mechanisms. However, a hublock can fail to function as expected. The single-control solenoid is also susceptible to water intrusion, rendering it useless. To check if yours is locked, follow these simple steps.
First, you should make sure your hub has not been damaged. If your IWE hub is damaged, it can cause a grinding noise. If the hub is not properly installed, it may also cause the axle to be damaged. If you want to fix your F150’s IWE hub, it’s essential to match the hub’s teeth to the axle’s. You can do this with a vacuum gauge teed into the IWE control system. In addition, you can check the grinding or whining of the hub.
Another step to troubleshoot the IWE system on your Ford F150 is to replace the IWE solenoid. The original design was not very reliable, and the newer IWE unit was not easy to find. Ford has a special repair tool for this purpose, called an “IWE Reflash.”
What Year of F150 Should You Avoid?
There are several years to choose from when purchasing a Ford F150. The CoPilot Compare website breaks down each year’s features and pricing to help you find the best balance between value and reliability. The Ford F150 is a popular pick-up truck that has a long and storied history. While it does have its fair share of benefits, there are some downsides to this classic vehicle.
The Ford F150 was introduced in 1975 and has undergone a number of upgrades, the most recent being the aluminum-frame. Although the truck remains one of the most popular vehicles in the world, certain years are known to have a higher risk of breaking down. The 2005-2007 model, for example, suffered from an engine defect and problems with windows. These years were also known to have high-mileage averages and poor reliability.
There are also certain years you should avoid when buying a used Ford F150. The 2003-2005 model years are the least expensive, but they tend to suffer from transmission problems. The 2014-2015 F150 has a plethora of problems, with faulty window regulators and spark plugs. But the good news is that both years sold close to a million units, and both have low recall numbers.
What is the Most Common Problems with Ford F 150?
If you drive a Ford F150, you probably have heard of the integrated wheel end, or IWE. An IWE is an axle/wheel assembly that has a locking ring over the hub side and fits over the axle. It locks, and the hub is pulled over the axle when it’s locked. Ford has redesigned this system to eliminate water ingestion and prevent grinding noise.
To test the IWE, stick the vacuum hose into the second hose feeding the front wheels. If the hoses don’t move, the problem is in the transfer case shift motor. The transfer case shift motor was also a common cause of IWE issues in the early years of the F150’s life, but has become more durable since 2004. The vacuum hoses are connected by plastic housing.
While the grinding noise in the front of the vehicle is usually not a symptom of a larger problem, it can be a warning sign for a more serious problem. In some cases, the IWE actuator itself may need to be replaced. The replacement actuator and IWE solenoid are cheap and widely available in the United States. A good IWE solenoid can help you avoid low-speed grinding while making turns.
What Does a IWE Do?
Until recently, the Ford F-150 was equipped with vacuum-operated hub disconnect systems, called Integrated Wheel Ends (IWEs). The idea was that these would enable the wheels to freewheel when the truck was in two-wheel drive. Now, however, Ford has incorporated a new electric-powered system with IWE actuators. That means a Ford F-150 can go from two-wheel drive to four-wheel drive without any problems!
Performing an IWE actuator check involves locating the actuator, disengaging the vacuum lines, and hooking up an external vacuum pump. Check that the teeth assembly of the IWE moves from the inside to the outside when the vehicle is lifted. If they move to the outside, the IWE is working properly. If they are not, check the rest of the system. If the valves are stuck or a part of them is damaged, replace it.
The vacuum in the intake system is used to exert a vacuum on the entire IWE system. The first check valve in the IWE solenoid locks the vacuum when it is operating at its highest level, while the second one is located before the IWE solenoid. The vacuum will then be released to lock the hubs for 4WD. However, the vacuum may leak, causing the failure of the IWE.
How Do You Test IWE Vacuum Lines?
How do you test IWE vacuum lines on your Ford F150? The first step is to remove the IWE vacuum lines. Whether water is visible or not, you can use a vacuum tester to confirm the IWE is still working properly. If water is present, the vacuum lines should be disconnected and blown out with compressed air. This is particularly important for the passenger side IWE, since water entering the IWE can cause actuation failure.
If you’re experiencing problems with your IWE system, you need to upgrade your TCCM module. If your Ford F150 has a previous version, you’ll have to reflash the TCCM module to allow it to operate properly. This will update the software and delay the IWE solenoid until it needs to be activated. Be sure to operate the vehicle for one mile after updating the TCCM module.
How Do Ford F150 Vacuum Hubs Work?
How do vacuum hubs work in a Ford F150? If your F150 is equipped with automatic locking hubs, you can activate them by turning the 4WD switch in the cabin. Upon activation, the two front axles spin simultaneously under power from the transfer case. The PVH hubs operate with the same vacuum reservoir as the HVAC system. When the driver applies vacuum to the system, the hubs engage, locking the vehicle into 4WD. When the vacuum is removed, the hubs disengage. A solenoid controls this function.
The Ford F150 uses a unique system of hub disconnections called the IWE. This system uses a vacuum to allow wheels to freewheel when the truck is in two-wheel drive. Unlike traditional hub disconnect systems, the new system uses a more modern electrical mechanism. While the hublocks on a F150 are still essentially the same, they are slightly different and go by the acronym EIWE, which stands for electric integrated wheel ends.
