You can learn how to perform a quick diagnostic on your System to ensure it is not malfunctioning? Read on for some tips. You may have a faulty actuator. This article will walk you through how to test your four-wheel-drive System on the fly.
Disengage Four-Wheel-Drive System
To disengage the Jeep Cherokee’s four-wheel drive system on the fly, slow down and push the shift lever back into 4H. While the vehicle is in neutral or gear, push the transfer case shift lever into 4-high. Once in 4L, the driveshafts lock together. This can cause driveline noise, binding, and Crow-Hopping, resulting in breakage.
Another reason the Jeep Cherokee four-wheel drive system doesn’t engage is the vacuum system. The vacuum lines that control the 4WD axle disconnect system can become disconnected, melted, or ripped off. To identify the problem, lift the Jeep and trace the lines back to the transfer case. Then, remove the plastic housing around the vacuum harness. Be careful not to break any parts of the plastic housing while working on it. Finally, reconnect the hoses in the correct order.
Some Jeep Cherokees have a four-wheel-drive system that can automatically engage the four-wheel-drive System when necessary. But if you ever want to disengage the System on the fly, you can do it manually. An actuator controls the transfer case. This small electrical motor engages and disengages four-wheel drive when needed.
If the Jeep Cherokee 4WD system fails to engage or disengage, the problem is usually related to the actuator. If the actuator fails to engage, the failure can be the motor itself, the internal gears, or the electronic actuator module. Another problem can be the vacuum system, especially in YJ Jeeps.
One solution is to install a 4×4 Posi-Lock system. This upgrade requires no technical knowledge and is simple to install on your Jeep Cherokee. Getting rid of 4WD problems is a great DIY project. By removing the old manual System, you’ll be able to control your 4WD System from inside your Jeep’s cabin. The System also works to replace the failed vacuum hose system.
Test Your System
Testing your Jeep Cherokee’s four-wheel-drive System is essential for safe, comfortable driving on the road. The Jeep Cherokee comes with various four-wheel-drive systems, including Quadra-Trac I and II, which offer varying levels of 4×4 capability. If you’re unsure which System is best for your needs, take your vehicle for a spin on a dirt road.
To test your Jeep Cherokee’s four-wheel-drive System, you’ll need a vehicle with all four wheels off the ground. Then, apply gas and watch the tires. If they spin freely, they’re likely working correctly. If they don’t spin, there’s a problem with the transfer case. To fix this problem, you’ll need to replace the transfer case. It may be a costly endeavor, but it’s worth it in the long run.
Another type of tester is known as the Active Drive II. This unit includes a 4WD Low mode and a neutral mode for flat towing. It uses a chain-driven mechanism and takes 21 or 23-spline input shafts. It also accepts BA 10/5 and BA 15/5 transmissions. The low range of the NP/NV-231 is 2.72, and the high range is 1.00.
If you want to test your Jeep Cherokee’s 4WD System, you’ll need to know precisely which System you have. The Quadra-Trac I uses a transfer case with a limited-slip differential. Both of these transfer cases use a gerotor to distribute torque. The new System is more sophisticated than the old one. However, the Quadra-Trac II transfer case doesn’t use LEDs. It’s also missing low-range mode.
Another option for you to test your Jeep Cherokee’s four-wheel-drive System is to turn the car on its side. By doing this, you can drive over rough terrain. The four-wheel-drive System will return power to the front wheels if the car can’t get traction.
In addition to checking the driveability of your Jeep Cherokee, you can also test the power transfer unit (PTU). Its central role is to connect the transmission and the front wheels. If it’s faulty, your Jeep Cherokee could lose all power while driving or fail to shift into the park when stationary. It could cause a crash and injury if you don’t engage the power transfer unit.
One way to test your Jeep Cherokee’s 4WD System is to take it on a trail. A well-defined trail will test the Jeep Cherokee’s 4WD System. Make sure you have enough tire traction to handle the terrain. If your Jeep Cherokee’s traction control is faulty, you need to replace it. However, you may also need to change your transfer case. It’s essential to keep your Jeep Cherokee’s transmission fluid cool during the long journey.

Check For Faulty Actuator
The blinking 4-wheel-drive light on your Jeep Cherokee can indicate that something is wrong. If the light stays on, you may need to check for a faulty actuator. The mechanism inside the actuator must be adequately lubricated and checked for wear and tear. If the light is constantly flashing, it could mean that the internal parts of the actuator are damaged. If this is the case, it is best to visit a mechanic to have the problem fixed.
Next, you need to inspect the linkage that connects the transfer case to the 4WD System. A faulty linkage could cause the vehicle to bog down in 4WD. Check for cracks and abrasions in the linkage. If the problem persists, you may need to replace the linkage. You can check the linkage to see if it is rusted. If it is, replace it.
In some cases, a faulty actuator can prevent your Jeep Cherokee from entering or exiting a 4-wheel drive. When this happens, the car will shut down and cause the vehicle to get stuck. In such a case, you should take your Jeep Cherokee to a mechanic right away to make sure it’s not a mechanical issue. Once the issue is identified, you’ll be able to remove the actuator and take your Jeep Cherokee out of the 4-wheel drive.
Another symptom of a faulty actuator is a service message displayed on the driver information center (DIC). If the maintenance message isn’t gone after the vehicle is turned off, you should go to a dealer. This error message is usually caused by a bad TCCM, button pack, or encoder motor. Check for possible causes to get your Jeep Cherokee back into a 4-wheel drive.
Another possible cause of a faulty actuator is a wiring issue. In this case, you can check the wires for corrosion and replace them if necessary. Sometimes the 4-wheel knob won’t work when you press it, and you may need to push it several times to force it to work again. It is best to get a professional to fix your Jeep Cherokee’s 4-wheel System in such cases.
While the PCM in your Jeep is interchangeable, the computer that controls the air-to-fuel ratio and the transmission is not compatible with the replacement. If this problem is the cause of your vehicle’s low fuel mileage, it may be time to replace the PCM. This is particularly true of older models because FCA changed the configuration of the PCM from 1998-onwards.
The transfer case motor is located in the rear of the transfer case. It is held in place by three to four bolts. Its wiring connectors should be free of slack and aligned. Likewise, you should check the gears for a faulty actuator. If the gear is not moving, check the transfer case gears. They may need to be replaced or the transfer case itself.
