What does the ESOF system on a Ford truck do?
What does the ESOF system on a Ford truck do?
This system includes an electronically controlled transfer case that allows you to shift the transfer case from a dash mounted switch. You can identify this system because the switch will display 2H / 4H / 4L. There will NOT be a 4A setting. The ESOF 4WD system provides 4×4 High engagement and disengagement while the vehicle is moving.
How does 4WD work in a Ford Super Duty?
The dash switch works by sending power to an electric transfer case shift motor, that shifts the transfer case for you. Unless you’re driving a Ford Super Duty (F-250 / F-350) or something really old, you likely have a switch on your dash to activate your 4WD. Locking Hubs – Yes on No?
What’s the 4WD setting on a Ford truck?
There will NOT be a 4A setting. The ESOF 4WD system provides 4×4 High engagement and disengagement while the vehicle is moving. It is operated by a rotary control located on the instrument panel that allows you select 4×2, 4×4 High or 4×4 Low operation. 2H (4X2) – For general on-road driving.
Can a Ford truck be driven in 4×4 high mode?
Note: The vehicle should not be driven in 4X4 High or 4X4 Low modes with the hub locks set to FREE as this condition may damage driveline system components.

How many gallons does a Ford F 350 have?
Vacuum (F-250/F-350 single-rear-wheel gas engines) / hydro-boost (F-250/F-350 single-rear-wheel diesel engine, F-350 dual-rear-wheel), ABS 17-inch steel on F-350 dual-rear-wheel; 17 & 18-inch steel on F-250/350 single-rear-wheel, 19.5-inch. on F-450 30.5 gallons with 141.8, 156.2 wheelbase, 38.0 gallons with 137, 158 and 172.4 wheelbase
Is the ESOF switch on in 4×4 mode?
In either 4×4 mode or whenever the engine is off, no matter where the ESOF switch is, there should be no voltage there. Further, each IWE has two vacuum line connections. There is a double rubber vacuum hose at each IWE.
What happens when you turn the ESOF switch to 4HI?
When you turn the ESOF switch to 4Hi, a couple things happen simultaneously. First, the TCM moves the lever in the TC to the 4Hi position. This engages the front driveshaft, with the internal TC clutch spinning it, the differential, and the half shafts up to speed very quickly.
What is the electronic locking differential on a Ford truck?
The electronic locking differential is a device housed in the rear axle that allows both rear wheels to turn at the same speed. The electronic locking differential can provide additional traction should your vehicle become stuck. You can activate the differential electronically and shift it on the fly within the differential operating speed range.

How to diagnose your ESOF-Ford F150?
Unplug the electrical connector. In 2WD (and when the engine is running) there should be voltage across the wire harness side terminals. In either 4×4 mode or whenever the engine is off, no matter where the ESOF switch is, there should be no voltage there.
Is there a way to lock the hubs on a Ford PowerStroke?
Yes, both hubs lock. the dash knob is just a vacuum operated way of locking the hubs to the end of the axle and also shifts the transfer case. just locking the hubs manually does not put you in 4×4 becasue it does not shift the transfer case (the magic knob on the dash does that too).
What’s the proper way to engage a lock on a Ford truck?
For proper operation, make sure that each hub is fully engaged and that both hub locks are set to the same position (both set to LOCK or both set to AUTO). To engage LOCK, turn the hub locks completely clockwise; to engage AUTO, turn the hub locks completely counterclockwise.
Is it possible to UN-engage auto locking hubs?
As for the auto hubs if you are going in reverse it is possible to un-engage a wheel depending which wheel has the most traction and for driving forward is I believe the opposite. Manually locking of the hubs locks them to the axel but then unless you have a limited slip or a locking diff you are still spinning the tire that has the least traction.
