Here are the main reasons that can make your F150 stuck in 4 wheel drive low. Generally, on a Ford F150, a four-wheel drive-low is beneficial for those conditions where the truck requires more torque, provides excellent traction, and results in a better driving experience.
Ford F150 can get stuck in 4 wheel drive low due to a faulty transfer case motor, broken switches, lack of lubrication, blown-out fuse, and faulty transfer case module. However, you can disengage it by putting manual hubs in free phase, using the 4WD high mode, shift gear, reverse truck, and then disengage it. Also, push the gas pedal, drive it in reverse, obtain the clicking sound and remove stuck.
In addition, once you are in the 4WD low, put the pickup in neutral mode immediately because mostly reversing resolves these problems.
In addition, according to a survey, 2004 to 2008 Ford F150 models have this fault more than any other model.
Also, it states that the models of 2020 to 2021 are free from these four-wheel driving faults due to upgraded systems and advanced transfer case modules.
Furthermore, around 34% to 45% of 4WD low stuck problems are due to lack of use and inadequate off-road driving skills.
Why is my Ford F150 stuck in 4 wheel drive low?
Several dangerous reasons participate in this unpredictable phenomenon, and all of them keep the truck in the lower fourth wheel driver for around 12 minutes to 2 hours. Also, a few of them require mechanical repairing and may cost you a fortune.
Typically, a four-wheel-drive switch facilitates continuous electric supply without any interruption and electrical surges.
Also, they locate inside the cabin compartment, on the dashboard section, directly connect with the battery electric power supply and have a plug and play process.
However, a switch does not perform due to corrosive material, old age, and other vulnerabilities.
However, these efficient tools help in the engaging and disengaging phenomenon in less than 2 to 3 seconds. But, at their vulnerable states, they result in four-wheel remains in low position.
However, the replacement of these broken switches is one of the best options for resolving such problems. Also, these are cost-effective items with minimum installation prices.
Lack of lubrication
The transfer case provides the free flow of electric current to both side axles with the help of the shaft.
However, in some situations, it does not work appropriately and produces unnecessary sounds. Also, it provides indications in the form of humming noises and grinding sounds frequently.
Furthermore, it is a clear sign about the transfer case components resistance, and the fluid level decreases.
In such situations, lack of lubrication on the internal chains and vulnerable gears stuck the F150 in the 4 wheel drive low.
Identify the orientation spot of unnecessary sounds. Then, add a high-quality lubrication product and bring the F150 out of 4WD.
Malfunctioning transfer case motor
Generally, the transfer case motor provides input signals, moderates the system, and handles the second and four gear shifts.
But, in its broken state, the responses are inadequate and result in one gear stuck in an F150.
Also, the engaging and disengaging mode becomes vulnerable, and you cannot handle the pickup according to your requirements and general instructions. As a result, the transfer case binds or keeps the trucks in a permanent neutral phase.
Both of these conditions are not beneficial for any truck user because it affects the driving performance.
However, it is an expensive motor and costs you around $500 to $600, and a professional mechanic can replace it in 20 to 30 minutes.
Few people avoid the use of 4WD low due to stable road surface and lack of driving skills. As a result, it dries out and results in the development of high resistance.
Also, it is not advisable to use the dry and non-moving 4WD because it results in critical problems.
In such conditions, use this feature every once a week and also maintain its internal situation. Also, use second wheel drive on the dry and mild pavements and prevent the stuck phase.
Vacuum leak prevention
In a few situations, the penetration of excessive surrounding air in the engine results in its inappropriate performance and generates harmful idling.
Also, all of it happens due to a vacuum leak, and the four-wheel gear system activates in such situations.
Also, it prevents the vacuum from leaking and pushes back the axle in the original position. In addition, during such prevention conditions, the gear mode does not work appropriately and stays in the low four-wheel drive.
Typically, in a Ford F150 hood compartment, a 30-ampere fuse supplies electric current to the transfer case module.
Also, it supplies voltage to the electrical shafts, gear module, and shifting modes. But, it fuses due to sudden electrical surges, inappropriate electric wiring, and excessive use.
As a result, the fuse supplies electricity to the gear sections, and the driver shifts the four-wheel-drive in a low phase.
Then, it blows out, and the 4WD remains permanently in that mode, and disengaging becomes impossible without repairing.
In such situations, open the hood compartment, and check the fuse. Then, disconnect it from the electrical passage, and replace it with a new and high-quality item.
Next, connect with the controlling mode passage and utilize in low and high modules.
How to get Ford F150 out of 4 wheel drive low?
Here are two beneficial methods to resolve this problem in less than 30 to 40 minutes. Also, the involvement of mechanical support depends on your budget and inappropriate skills.
Furthermore, use these methods by identifying the relevant problem and handling it as a technical fault.
Method of hub checking and driving
In this step, turn on the vehicle without driving and allow the engine warming. Then, check the manual hubs and consider that they are in the free phase before starting the procedure.
Also, if they are not free, then bring them in that phase or take expert help for such modifications.
The vehicle stuck in the low mode and bringing it back to the other high wheel drive is challenging without using the manual engaging/disengaging phenomenon.
Also, for this purpose, set it to the four high wheel drive mode. Then, forcefully drive the pickup and cover a distance of half or a full mile.
Stop your pickup without disturbing the phases. Then, bring the 4WD into a second-wheel driving state.
Now, reverse the truck slowly and cover a distance of 17 to 20 feet without any further changes.
Slowly drive the truck backward and wait for the disengaging sounds. In this way, the parts get loose, and they disconnect from the permanent low point.
Also, it requires patience and skilled slow driving because haste results in component damages.
Method of transfer case replacement with pedal pressure
Access the gas pedal and slightly press it with your feet. Then, put your Ford F150 in neutral mode and turn the switch towards the second-wheel drive. Now, apply steady and high pressure on the gas pedal.
Press the pedal with a particular pressure range but never apply excessive force because the gas pedal can break. Also, access the disengaging click, and once you attain it, it allows the transfer case to stabilize.
Then, change the broken components like the motor and a blown-out fuse. Also, put the truck in reverse and stabilize the transfer case in 2 to 3 attempts. In this way, the stuck four-wheel low comes back to the standard position.
Average cost and required time
Generally, it depends on the type of fault and complexity of the module. However, on average, the overall repairing process may cost you around $150 to $600 with negotiable packages.
Also, it includes the price of broken items and labor charges. Furthermore, the identification of the fault and repairing is a time taking process.
Also, the average time to resolve this problem is approximately 20 to 40 minutes depending on the problem type.
