Your problem is probably the front axle solenoid. it is in the center of the truck on the front axle and it is really easy to change. Simply unplug the electrical connector and use a wrench to loosen it. Spin it counter clockwise until it comes out........Manual hubs i believe are not available for this truck but i think there is a aftermarket cable you can buy and install to lock the front diff in.

SOURCE: four wheel drive wont engage

If you have push button 4-Wheel Drive, it is recommended that you use it every once in a while, in order to keep gunk, rust, and corrosion to build up on moving parts. The mostly likeley (though not definite) reason would be that you let the 4-wheel drive unused for so long that corrosion has built up on the parts and the actuator that engages the 4-Wheel Drive doesn't have the power to engage it past the corrosion. You'll need to take it in to be cleaned, or to have parts replaced. In the future, every month or so, engage 4-Wheel Drive and drive around in some mud, grass, sand, or any other loose ground for a bit, just to keep the parts moving and clean.

The service Four wheel drive light is to alert the operator the system is not being read properly by the ECU.

If the ECU loses contact with or position of the Transfer case actuator motor the service light will come on. Same thing goes for the front diff actuator.

So it may be a bad switch, sensor, or an actual problem in the 4WD linkage. This is not a Oil Change light that you can ignore a few extra weeks - it indicates a problem that should be taken care of ASAP to avoid costlier problems down the road.

the actuator for the hub locking is faulty and not engaging the hub correctly. There may be badly worn teeth to engage or broken parts in the hub.

Make sure that the vacuum hose connector is connected AND connected correctly at the transfer case and at the front differential. If that is all right and the front differential still doesn't engage, then you need to test the vacuum actuator at the front differential.

Transfer case on 2006 F150 will engage but no power to front wheels?


SOUNDS LIKE A BAD HUB TRY THIS TO DIAGNOSE THE PROBLEM

Put the transmission in park, set the parking brake and raise the chassis so one of the front wheels is off the ground while the other is still on the ground. When the transfer case is in two-wheel drive, the hubs should be released allowing the wheels to turn freely when spun by hand. If the axle shaft turns when you spin the wheel, it means the hub has not disengaged.
To check engagement, rotate the axle shaft backwards. This should lock the hub. Try turning the wheel by hand again. The axle shaft should now turn with the wheel if the hub is locked. If the hub fails to lock, the hub will have to be disassembled and inspected or replaced.
To check release, hold the axle shaft steady and rotate the wheel backwards. You should hear a click as the locking mechanism slides back out and disengages the hub. Rotate the wheel forward again and it should turn freely.
Another way to check the hubs is to raise the vehicle on a frame contact lift so all four wheels are off the ground. Then start the engine and place the transfer case in four-wheel drive and the transmission in drive. If the front wheels don't turn, look at the front axle shafts. If both shafts are turning, but one wheel is not, the problem is a bad hub on the wheel that isn't turning. If the front driveshafts are not turning when the transfer case is in four-wheel drive, the problem is inside the differential (broken side gears) or the transfer case (broken chain, shift linkage, etc.). If the driveshaft between the transfer case and differential is turning, the problem is in the differential. If the driveshaft is not turning, the vehicle is going to need repairs to the transfer case.
Hope this helps.

If you are seeing the front drive shaft turn,Then it is in four wheel drive,
Your truck has automatic lock in hubs,The most common problem with Rangers is that the lock in hubs get worn and wont keep the axle engaged to the wheel,
If you go to Auto zone they have new lock in hubs for around $50.00
Or you could up grade and get hubs that you manually turn and lock in.

Four wheel drive wont engage. Tranfer case is


Sounds like you either have a vaccum leak or your 4 wheel drive actuator is not working to engage the front differential.On my 98 ram there is a black and red plastic lines that are used for the vaccum lines. They are underneath and go from the transfer case to the front axle, check to see if one or both might be cracked or broke completely.If the lines are good then it could be your actuator on the front axle. A new one is about $93 at advance auto parts and not very hard to replace

On the front diff is a solenoid that locks in the four wheel drive. This is a common part to replace. Very easy also.

When i put my 03 chevy 4x4 in 4 wheel drive there is a loud popping sound and 4wheel low truck wont move it a push button 4 wheel


you may have a broken transfer box or a damaged locking hub on the wheels that arent used in 4x4 mode, i.e. if your car is FWD unless its in 4-low, check the rear locking hubs for failure. Other wise it sounds like a transmission fault in the aforementioned transfer box or differential.
