What is a Esof solenoid?
It is what locks/unlocks the front hubs when using the ESOF selector switch.
How do Ford vacuum hubs work?
For this design, the vacuum is placed on the system unlocking the hubs while the truck runs in 2-wheel drive mode. When shifting to 4-wheel drive, vacuum is released, which locks the hubs. This leaves the front axle locked for fail-safe operation.
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.
Can you test a four-wheel drive actuator?
Test all four wheels before driving off just to make sure they are working properly! The vehicle should then be able to move in reverse or forward and at least four different speeds if not more. If this does not happen, there might be an issue with your actuator!
What does IWE stand for Ford?
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.
What does Ford IWE stand for?
How do you check auto locking hubs?
If the hub fails to lock, the hub will have to be disassembled and inspected or replaced. To check release, hold the axle shaft steady and rotate the wheel backwards. You should hear a click as the locking mechanism slides back out and disengages the hub. Rotate the wheel forward again and it should turn freely.
How to test a solenoid with a multimeter?
For the final solenoid test that would determine if your solenoid is damaged or not, you would have to connect the red probe of your multimeter to the negative terminal of the solenoid, and the black probe of the multimeter to the positive terminal.
How do I test the IWE solenoid?
You should be able to test the signal to the IWE solenoid from the 4×4 control module with a digital volt meter. Unplug the electrical connector. In 2WD (and when the engine is running) there should be voltage across the wire harness side terminals.
How to tell if the solenoid is bad on a car?
Again, you should have an assistant to turn on the engine, as you check the reading on the multimeter, it should drop half a volt just as it did in the previous voltage test, if it falls less than 0.5 volts, there is a problem inside your solenoid.
What is a solenoid in electrical appliances?
Solenoids are found in almost all electrical appliances, from electronic door locks to the more complex machines. It is an integral part of your electrical system switches, like your vehicle engine starters. To carry out this test would be a more straightforward task if you already know about the instruments needed for this analysis.
