SOURCE: front end will not lock in in 4x4 transfer case is

Ok, this is probably going to sound greek if you have no automotive experiance, so here goes:

There are 2 possibilities I can think of at the moment depending on your 4wd system, however there are several things that can cause this

If you have a Push button 4wd (you push a button or turn a knob) the system engages using actuators or sylinoids meening you turn the 4wd on, the switch sends power to the selector option (high and low) and the 4wd light on the dash. the selector determines where the actuator/silenoid engages (either high or low) in the transfer case. However the actuator or silenoid can be faulty and yet the system will say 4wd is on because the switches still sending power to the 4x4 light

The next setup is the manual linkage set up, and given the year of your kia I doubt you have this setup However I am going to go through it anyway.

With a maual linkage setup you engage the trasfer case maualy using the 4wd shifter. Ironically on newer manual shift 4wd systems the dash light is still triggered electrically by location of the shifter not what is going on in the transfer case (Ah a flaw in the design) So if you linkage is loose/bent/damaged or somehow disconnected your 4wd wont engage but the light will still show that it is! Hope this helps

SOURCE: front end will not lock in in 4x4

f it's a later model Ford, the rubber vacuem lines may be off or dryrotted. This will cause the no 4x4 lock-up but lights indicate it's working in 4x4..Easy to replace lines from back of front hubs.This was the case on my 2000 f-250, but I have front hubs that need to be locked in or out by turning the center knob also..

Check your hubs lift front end if wheel does not turn when locked in 4x4 then hubs are not engaging turn wheel by hand or a pipe wrench on drive shaft do not try power unless all wheels are lifted

I have a 1979 ford f250 4x4 and the tranfer case will go in but it wont turn the front driveline


I am a bit rusty on the 22 year old part. Someone else may be more informative, but on some of the 4x4 actuators they used different methods of moving the internal parts.

The actuator used to be Vacuum operated and the part would move a certain distance to put the transfer into high or low mode. If the actuator did not fully extend or contract you would be between gears; sort of in Neutral.

You are now faced with the front driveshaft free-wheeling(But which end?). Disconnect one end of the front driveshaft so you can feel whether the transfer case is free-wheeling or if the other end of the shaft is turning anything in the front axle. With the front hubs locked, the front driveshaft should not turn or if jacked up, the tires should spin when the front driveshaft is turned by hand.

When you are assured that the front axle is fine, then the problem can only be the transfer case. I remember people had a lot of trouble with the actuators.

I hope this gives you a way to test which end of the front driveshaft is the problem.

There are some Blogs on the internet like Ford4x4Owners.com and Off-Road Blogs which can be very helpful. I hope my suggestion helps.

Operationally vacuum holds the IWE ( Integrated Wheel Ends ) out, and once vacuum is removed the spring engages the IWE.

Lift and support the front of the truck so the front wheels are off the ground ( take safety precautions, chock wheels, jack stands, etc )
Key on, engage 4x4 and try to turn the front drive shaft.
- If it turns it is a problem with the transfer case.
- If it doesn't it is a front axle engagement problem.

- If the front drive shaft does not turn :
1.Shut of the truck ( still jacked up, and supported ) remove the vacuum lines from the IWE. The spring should push the gears in, without the vacuum line on.
2.Check the vent line ( tube that is routed into the engine compartment with nothing attached to it ), for blockages.
3.If the vent line is clear, and with the vacuum lines off the IWE should be engaged ( both front wheels locked ).
4.If they lock, the problem is with the IWE solenoid not shutting off vacuum to the IWEs. There is a TSB on the 2004-2006 IWE solenoids, a newer revision has been made, and used from 2007 and newer MYs.

- If the front drive shaft turns:
1.Check the fuses for the 4WD system ( If ESOF system ) . These are #11, #29, #30 and #111. Use a meter to check the fuses while plugged in, there are pins on the back of the fuse for this. Use a known good ground and check each side of the fuse with the other meter probe, with the meter set to V-DC ( check the scale if a setting that it will read at least 13 V DC ).
2.With the key on, if the ESOF system have someone turn the mode selector from 2WD to 4WD while hitting the transfer case with a dead blow hammer ( do not use a metal hammer, it can damage the transfer case ). Some times the shift motor will get stuck ( lack of use ? ) and the dead blown hammer will free it up.
3.There are 2 relays ( in the small engine compartment fuse / relay panel - ESOF only ) for the 4WD system, one is the CW ( **** Wise ) one is the CCW ( Counter Clock Wise ). These are full size relays, that can be bench tested, or a quick remove and replace test with the high beam relay in the cab fuse panel ( Relays R03 ). 1 at a time, remove the CW & CCW relays and install them in the position for the high beam relay, and test the high beams by pulling back on the MFS ( MultiFunction Switch ). If the high beams work with both relays, the CW & CCW relays are not the issue ).
4.Check the connector on the transfer case for the shift motor, to make sure it is not corroded.

Dash selector does not engage 4x4 hi or 4x4 low, Used it for maybe 1 hour total since 2006 when pourchased new F-150

Here is a block diagram of the IWE system
sscullys_35.jpg

If the front drive shaft turns, it is either the connector to the transfer case or the transfer shift motor not functioning correctly.
Check the connector for corrosion on both the male and female pins.
Turn key to run ( do not start ) and have someone turn from 2WD to 4H and back again while hitting the transfer case with a dead blow hammer ( not a steel hammer ) to see if the shift motor is hanging up.

Not sure if selector does not engage 4x4 hi or 4x4 low means the lights on the mode selector switch do not change, or if the switch selects 4H, but the front wheels do not function, so hard to provide a true direction on where the problem could be.

Is the system ESOF ( Electronic Shift On the Fly ) or MSOF ( Mechanical Shift On the Fly ) ? Lift and support the front of the truck so the front wheels are off the ground ( take safety precautions, chock wheels, jack stands, etc ). Key on, engage 4x4 and try to turn the front drive shaft. If it turns it is a problem with the transfer case. If it doesn't it is a front axle engagement problem.
