I had the same problem with my 98 sierra 4x4. Turned out that the electrical activator on the transfer case was not working. It will still go into 4 low but not 4 high. Replace the electrical switch on the transfer case and it should work again.

Stuck in 4x4 low switch on dash 1998


It is your 4 x 4 electronic shifter at fault. Located on your transfer case it is mostly black/brown plastic electronic switch that engages and disengages your transfer case from low, high 4 x 4 or 2 wheel drive.
Check connections for electric continuity and replace it if there is no power...

I have 2003 RA Holden Rodeo 3.0 ltr T/Diesel. The 2 front wheels don't seem to be engaging when i put it into 4wd (high or low range). I can hear the high and low range click in when i press the buttons...


Does yours have AUTO hubs, there are some luxory models have auto hubs, these rely on difference in drive on the axles,(wheel spin) others have manual locking hubs, these actually need to be engaged manually, these require you to twist the centre of the hub to engage and disengage the front hubs, these sometimes require you to reverse to disengage properly, Rodeo had both depending on model.

How do I turn 4wd on?


    • 1 Start your Dodge truck's engine.
    • 2 Turn the electronic transfer case from "2WD" to "4WD Lock" to engage the high range 4WD, if the dodge truck is equipped with an electronic transfer case; otherwise, shift the transfer case lever from "2H" to "4H." The electronic transfer case is located on the instrument panel and is marked with "2WD," "4WD Lock" and 4WD Low." The lever-equipped transfer case is located to the right of your leg and is marked with "2H," "4H" and "4L."
    • 3 Shift the transmission into "Neutral" while the vehicle is either stopped or rolling at 2 to 3 mph to begin engaging in the low range 4WD. Turn the electronic transfer case to "4WD Low," if the Dodge truck is equipped with an electronic transfer case; otherwise, shift the transfer case lever from "2H" or "4H" to "4L."
    Tips & Warnings
    • Indicator lights will come on and alert you that your vehicle is in either the high or low range of 4WD.
    • Do not engage in the low range of 4WD drive if the transmission is in gear; you must shift to "Neutral" first.
    • Many Dodge trucks allow you to shift from 2-wheel drive to the high range of 4WD at up to 55 mph--consult your truck's manual to ensure that this is possible. Do not exceed 55 mph while engaged in the high range of 4WD. Do not exceed 25 mph while engaged in the low range of 4WD.
    • Do not engage in 4WD unless you are on slipper or rocky roads.

When turning a tight corner the front wheels will skid and seem to bind. 4wd high lite is not on but will come on when engaged.


Have a look at steering tie rod and tie rod ends, make sure they don't have free play, it might just need some adjustments, and if 4wd light comes on when engaged is normal and not related to front wheels problem you have. Have a look at it and comment back if you need more advice. Best

Front end will not lock in in 4x4 transfer case is in & dash lite shows 4x4 but front wheels don;t lock in


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

1996 ford explorer 4wheel drive will not engage into the hubs need to know how it works


make sure your 4WD switch is working.and fuse is okay.because your 4WD is control by 4 electric shift motors in which drive a rotary cam which moves the mode fork and range fork inside the transfer case to select between 2WD HIGH A4WD - 4WD HIGH AND 4WD LOW RANGE.a shift motor sensing plate on the shift motor monitors the range in which the transfer case is operating a transmission range sensor monitors the gear position of the transmission.which must be in neutral to shift into low.a pair of solenoids one for 2WD one for 4WD.mounted on the upper right firewall route vacuum to the vacuum motor which engages and disengages the center axle disconnect collar in the front axle assembly.a 4 x 4 shift motor relay module contains two GEM controlled relays which shift the transfer case shift motor between 2WD and 4WD modes.a solid state clutch relay activates the A4WDclutch inside the transfer case.

Intermidint cluncking noise from front


That sounds like what may be happening is the "Vacumm Motor" that locks and disconnects the front axle is binding and not engaging all the way. Or possibly the vacumm supply is not sufficient. Trace the vacumm hoses and look for oil contamination or other damage. You may want to hook up a vacumm guage and check the two hoses. One will have vacumm on 4WD engage and the other on 2WD. You should see the same amount both ways.
Make sure that the 4WD engage lite works too. That would be the electrical switch on the front axle. It should turn on a indicator lite on. (I believe all models are equipped with one with that system)
And before you're done you should inspect all the u-joints and drive axle Constant Velocity joints for wear or the presence of rust around the caps. If there is rust around the cap it is probably full of rust instead of grease (bad) It good to check those periodically but those shouldn't be creating you're noise intermittently.
Let me know how that works for you.

4 wd low range will sometimes engage 4wd high will never engage


I had a very similar problem with my 98 gmc 2500. The 4 low would engage - though the upshifts were erratic, but no 4 high though the light sometimes came on. I changed out the electric shift solenoid or whatever it is called, on the transfer case and it worked fine after that. A fairly simple fix that can be done in 15 minutes. Hope this helps.
