Five Easy Steps in Removing the Transfer Case Vacuum Switch
In four-wheel-drive vehicles, the transfer case engages to allow four-wheel drive capability, and disengages to bring the power back to just two wheels. Because of its task and its location at the bottom of the transmission, the transfer case needs to endure a huge amount of stress as it provides the driveshaft with its needed power coming from the engine. In many modern cars and SUVs, transfer cases transmit the power through a chain. Since the chain, transfer case, fluid and vacuum lines, and the vacuum switch work hand in hand, any problem with one of these components can affect the functions of the transfer case. If there are noticeable signs of transfer case vacuum switch problems or, if after troubleshooting, you find out that it is the culprit behind your transfer case problems, replace it as soon as possible. Here are the steps in removing a malfunctioning transfer case vacuum switch from a Cherokee:
Difficulty level: Moderate
Things you'll need:
- Socket set
- Jack stands
Step 1: Open the hood and take off the negative battery cable using a socket set.
Step 2: Jack up the vehicle's rear end; do not lower it until the jack stands are securely positioned under the rear frame.
Step 3: Go under the vehicle's rear end and find the transfer box. In some vehicles, including your Cherokee, it can be found just behind the transmission.
Step 4: With the right socket, loosen and remove the bolts securing the transfer box in its place. By doing this, you will have access to the transfer case switch.
Step 5: Inspect the wiring harness at the back of the switch for signs of damage. If there's none, unplug it and pull it out. Install the new switch.
Removing a malfunctioning transfer case vacuum switch is as easy as that, so why endure transfer case problems if you can immediately fix it by installing a brand-new switch?
