    No its got manual hubs on it.

  • tech2504 May 11, 2010

    For clarification and help in diagnosis, do your front hubs disengage when turning the switch to 2wd mode?

    If it has a 3 position switch on the dash board for 2wheel high or 4wheel high or 4wheel low It has auto locking hubs witch can also be locked in manually They will only llock in by the dash board switch when the truck is moving. It is a shift on they fly system that can be used at speeds up to 55mph

2003 ford f250 superduty 4x4 don't work no indicator light on dash changed4x4 switch module what next?


Check for codes. Usually part stores do it for free. here is how it works.
Principles of Operation

Electronic Shift on the Fly (ESOF) System

The electronic shift on the fly (ESOF) system is an electronic shift system that allows the operator to choose between 2 different 4x4 modes as well as 2-wheel drive. The operator can switch between 2H and 4H mode at speeds up to 88 km/h (55 mph). To engage or disengage 4L, the 4x4 generic electronic module (GEM) requires that the vehicle speed be less than 5 km/h (3 mph), the brake pedal depressed and the transmission in NEUTRAL (or clutch pedal applied on manual transmission vehicles). This system contains pulse vacuum hublocks (PVH). The selector on the hublock, when turned fully counterclockwise to the AUTO position, engages/disengages the hub depending on the driver-selected 4x4 mode of operation. The hublocks also contain a manual override. When the selector is rotated fully clockwise to the LOCK position, the 4x4 vacuum and electronic system used for coupling the front axle to the wheel is bypassed.

The transfer case is equipped with a dual-cone synchronous clutch. This clutch is used to synchronize the front driveline to the rear. All other internals operate in the same manner as the manual shift system. When the mode select switch (MSS) on the instrument panel is turned, the 4x4 module powers the transfer case motor, which activates a shift fork and engages the clutch. When the shift motor reaches the desired position, as determined by the encoder position inputs to the 4x4 module, power to the shift motor is removed. When the transfer case front and rear output shafts are synchronized, the lockup collar mechanically engages the mainshaft hub to the drive sprocket. At this point, the front axle PVHs are engaged. Instrument cluster "4x4" and "Low Range" indicator operation is controlled via hardwired outputs from the 4x4 module.

Electronic Shift Transfer Case

The New Venture Gear NV 273 electronic shift transfer case is a 3-piece aluminium design. The unit transfers engine power from the transmission to the front and rear axles. Under normal driving conditions the unit is in 2-wheel drive high (2H), but when desired, the operator may shift into 4-wheel drive high (4H) or 4-wheel drive low (4L). The transfer case is shifted electronically. The unit is lubricated by a positive displacement fluid pump that channels fluid flow through holes in the mainshaft.

The encoder assembly used for mode indication is of a Hall-Effect type. The system uses a total of 4 independent transistors for mode recognition. Each transistor is associated with a specific range of motor movement. When the circuit to each transistor is closed, a ground path to any of the A, B, C or D encoder pins is accomplished. When the circuit to each transistor is open, the connection to any of the A, B, C, or D encoder pins is pulled to voltage. Mode indication is "decoded" by the 4x4 module based on the varying combinations of signals coming from the transistors.

Hublock Operation

With the hublocks in the Auto position, the 4x4 ESOP system uses timed vacuum sequences to lock and unlock the wheel ends when switching the instrument panel MSS between 2WD and 4x4 modes. A high vacuum level (222 mm or 8.75 in. Hg and greater) is applied to the hublocks to lock the internal spring mechanism that engages (locks) the hublocks for 4x4 mode, and a lower vacuum level (114 to 184 mm or 5.9 to 7.1 in. Hg) is applied to unlock the spring mechanism that disengages (unlocks) the hublocks for 2WD mode. The vacuum signals are supplied to the hublocks by system components, including the 4WD control module or GEM, wiring harness, solenoid, vacuum harness and vacuum seals. As a first step in service, eliminate obvious items such as loose wiring connections, loose vacuum connections or damaged vacuum lines.

FUSE BLOCK OR FUSE? AND IF NOT THAT THE SWITCH OR THE SHIFT MOTOR.. ITS ON THE TRANSFER CASE LOOKS LIKE A WIPER MOTOR.. CHECK WIRING ALSO.. AND PLUGS ON SHIFT MOTOR.

Ford f250 superduty 2008. Stuck in 4low. We can change it manaully. Motor good. Relays good. Everything good. but just wont switch over.


I can give you 2 more things to try. The turn knob is perhaps cracked on the backside of the knob. Knobs like this are similar to the heater control knob. When cracked, they spin around the shaft without turning it. You can sometimes get them to bite onto the shaft 1 way and slip when turned the other way. Pry off the knob and check.

Electronic shift solenoid type transfer units work off of 1 wire with variable voltage moving the shift solenoid to different lengths inside the transfer case. If the selector light on the shift switch burns out, it can throw off the shift solenoid from moving to the proper position. Removing the electric plug at the transfer case and placing a voltmeter on it, you would have a helper turn the transfer switch to its different positions and measure the electric values. They should progressively match each selector position.

2002 f250 transfer case that doesnt shift into 4x4


Hello , chances are the 4x4 transfer motor/solenoid on the case either has no power , or has failed. I removed mine from my 2004 Explorer , dis-assembled and replaced the nylor washer and re-assembled and she works.

Transfer case wont engage


shift into 4wd and move truck a couple of feet.
if light is still off, park truck block the wheels set the park brake jack right front wheel and try to hand spin the wheel if wheel doesn't turn 4x4 is functioning properly but there is a wiring problem use an ohmmeter to check the 4x4 switch wiring fuse and bulb
if wheel turns freely the front axle or transfer case is not engaged
attempt to hand spin the front driveshft if the driveshaft will spin the transfer case is not engaged check the transfer case shift linkage, problem is in linkage or transfer case internals
if the driveshaft will not spin the transfer case is engaged properly
with trnsmission in neutral or park start engine measure vacuum on the two vac lines at front axle shift motor . one line should have approx 20" vacuum. other line should have none
if no vacuum measured look for vac leak or bad vac switch
if both lines have vac look for a bad vac swithc or ruptured cad actuator diaphragm
if one line has 20" +- VAC
move transfer case lever to 2wd measure vac again lines should have swapped vac signals
if no vac switch bad or 4wd shift likage needs adjusting
if yes vac motor bad or stuck or shift fork stuck
remove vac shift motor from the axle attach vac lines to shift motor engage disengage 4wd
does shift motor plunger move at least 1/2 inch
no shift motor bad
yes check axle shift fork and vac motor for binging

I have a 2002 ford f 250 it will shift to 4 high but not to 4 low


I have a 2000 F250 occasionally i have this trouble to. It may sound simple but i have had to hold the brake for a while and turn the knob to low range while holding the brake. One time my transfer case was in a bind though and had to take the three bolts out and put a crescent wrench on the rod sticking out of the transfer case and shift it manually. Sounds a little excessive but i has worked for two years now. Until recently now it shift in to 4 high but won't come out it. Hopefully this helps.

Can,t get truck out of 4x4 low range


try putting your truck in neutral and then shifting into 2 wheel drive shift on the fly does not apply to 4 low only 4 high and on electric shift models it wont shift unless your ****** is in neutral.
