Check that the hub locks are engaging and that the selector actuator is actually putting it in 4wd.

SOURCE: 1994 22re 4x4 problem

your transfer case is not working properly, try this trick, shift into 4wd and gently back up the car and go forward and back up again wait for the indicator light to come back again, goodluck, otherwise you need to have those transfer case checked and maintained, have those front hubs checked and maintained too. Its would be better to use your 4WD more often. Try this trick not on a paved road pls.

SOURCE: 4x4 wont engage

There is a switch that has twwo wires going to it, it's located just above the motor on your transfer case,on the drivers side, one plug goes to the motor and the other goes to this switch, it's the motor that shifts it into low and high range, I'm not sure what the switch is called but it tells the front end when to lock and unlock.
Hope it helps

SOURCE: 2002 kia 4x4 wont go into 4 wheel drive

Hello
A VERY COMMON FAULT!
Kia us a dim design that works on air, so the light on the dash may light up green...mine does...but no 4x4.
Test one, look inside the engine bay,(2Litre petrol) on your left hand side, to the left of the actual engine is the solenoid device that "switches on" the vacuum to the front hubs. This is easier that you would think. If you look at the left side of the engine, there are two pipes coming out (left side) one is thick (break system. DONT touch) one is thinner and soft rubber. Follow this tube, it goes into a small black cannister which is a resvoir and one way valve...the tube then outputs into another device (solenoid) which has 2 wires on. The tube then splits under this in two. The test is simple, with the engine running, and 4 wheel drive engaged pull the tube apart after the solenoid. Put your finger there you should feel a nice strong ****. If it does **** put it back on. If it does not **** it needs to be removed and cleaned. This is simple to unbolt and all you do is pull the rubber bung of the bottom, and the two tubes and spray break cleaner inside. reassamble until you get to feel the vaccum.

test 2 Now look behind each wheel, you will see a thick hose wrapped in a spring, this is the break system, do not touch this. There is a thinner flexible hose attached behind the wheel, you will notice that these have no securing system just push fit. Remove each of the in turn and test for vacuum.

Leaks here are common and easy to fix.

The bad news if you have vacuum, and still no 4 wheel drive one or both front wheel hubs has a leak, and the bad news is, it needs a garage to fix it, and to replace the seal a £5 part you have to ruin a £100 part.

Test the vaccum, pray. Otherwise ask, doe you really need to spend £250 to sort this?

Good luck

SOURCE: 4x4 transimission clunks when engaged?

When engaging the 4WD system, you are pulling the lever on the Transfer Case right? Not the transmission, it's a different gearbox.
There were several versions of transfer cases that used both full and part-time 4 wheel drive.
From your description this sounds like a part-time transfer case.
Going with that, it is somewhat normal to hear and feel a mild clunk when engaging 4WD high range, especially if you are at a complete stand-still or under full throttle.
Try engaging 4WD High while slowly rolling at idle - no throttle. It should pull in fairly smoothly.
Once 4WD is engaged it will literally LOCK the front and rear axles together. So do not do it on hard dry pavement.
These older style 4WD systems need a little "give" especially when turning. The engineers assume you are not engaging 4WD unless you are in a somewhat slippery scenario.
Many CV joints, axles, U-Joints, differentials, and transfer cases are damaged and broken by folks who don't understand this.
Reading the owners manual should provide a clearer description of what you've got.
Bear in mind that when you come out of 4WD it may not completely release, again due to hard pavement binding up the axles. You can try this: backing up 10-25 feet in a straight line, or getting one set of wheels on the shoulder or in some gravel. That should allow it to release the transfer case and go back to everyday 2WD high.
I hope this helps.
:)

I can feel my trooper shift into 4x4 but I'm not


I had this happen on my 94 automatic. 4x4 "engages" but no power to front wheels. One of the front axles went bad so the 4x4 doesn't engage on either front wheel. It was a $800 fix.

I have a 91 k1500 ext. cab 4x4 and my 4 wheel drive wont engage . what all could it be?


SOLINOID ON FRONT AXLE IS MOST COMMON PROBLEM. CHECK FOR POWER ON BLUE WIRE AT SOLINOID ON FRONT AXLE. KEY MUST BE ON WITH SHIFTER IN 4X4. CHECK FUSE FIRST I THINK IT IS THE SAME FUSE AS RADIO.

How does the four wheel drive on my jeep work or lock in?


If you have a CJ or Cherokee, when you move the 4x4 lever, it engages the transfer case which then transmits power to the front as well as the rear wheels. For most (99%) of all four wheel use, you use the front position on the shifter one notch behind the two wheel drive setting. Use 4 low only for pulling vehicles out of mud etc and don't drive in that range. If it sticks in 4wd after disengaging it, usually backing up about twenty feet will help.
If you have a Grand Cherokee, the 4x4 usually is a quadratrack unit. That one stays engaged but only goes into 4wd mode when the rear wheels begin to slip. (by itself). Rules for using low are the same.
It is very important to run the exact same size and style tires on any 4x4. It is mandatory on quadratrack units. Use of odd sized tires can cause driveline damage.
There are variations on different year vehicles but the basics remain the same.

My 2002 2500HD 4x4 front axle not engaging


Try jacking up one side of the front and putting it on a jackstand. Then turn key on(but dont start it) and put it in 4hi. Try to spin the tire in the air. The drive shaft should not turn nor the wheel. If the wheel does then maybe the acuator is not moving in the axle. It worked when you pulled it out but it might be hanging up on something in the axle.

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
