Understanding the 2018 Dodge Journey AWD System

Before we jump into the problems, let's quickly review how the AWD system in the 2018 Dodge Journey works. Knowing the basics helps you understand why certain issues arise. The Journey's AWD system typically operates in a front-wheel-drive (FWD) mode under normal driving conditions to conserve fuel. When the system detects wheel slippage – for instance, when accelerating on a wet surface or when encountering snow or ice – it automatically engages the AWD, sending power to the rear wheels to provide additional traction. This system uses sensors to constantly monitor wheel speed, throttle position, and steering angle to determine when to activate the AWD. This seamless transition is what makes AWD so appealing, as it improves stability and control without any input from the driver. The system's effectiveness is largely dependent on the condition and maintenance of its components. Regular checks and timely repairs are crucial to ensure the AWD functions correctly and safely.

Key Components and Their Roles

The 2018 Dodge Journey AWD system comprises several key components working together to ensure optimal performance. Each part plays a critical role in the system's function, and knowing these components can help you identify where problems might originate. First, there's the transfer case, which is the heart of the AWD system. It's responsible for distributing power between the front and rear axles. Then, there's the front and rear differentials, which allow the wheels on each axle to rotate at different speeds, which is essential when turning corners. The driveshaft connects the transfer case to the rear differential, transmitting power to the rear wheels when AWD is engaged. Finally, there's the electronic control unit (ECU), which monitors the various sensors and controls the engagement of the AWD system. The ECU uses data from these sensors to determine when to engage the AWD. Any malfunction in these components, whether it's a leak in the transfer case, a worn differential, or a sensor failure, can lead to AWD problems. Maintaining these components with regular servicing, such as fluid changes in the transfer case and differentials, is crucial to prevent premature wear and ensure the system's longevity.

How the System Operates: From FWD to AWD

The transition from front-wheel drive to all-wheel drive in the 2018 Dodge Journey is a marvel of engineering, designed to be as seamless and unnoticeable as possible to the driver. Under normal driving conditions, the vehicle operates primarily in front-wheel drive mode to maximize fuel efficiency. This means that power is directed only to the front wheels. When the system detects a loss of traction, typically through sensors monitoring wheel speed, the AWD system kicks in automatically. This is usually triggered by wheel slippage, such as when accelerating on a wet road, encountering snow or ice, or when the vehicle's electronic stability control system activates. The electronic control unit (ECU) plays a key role in this process. It processes data from various sensors, including wheel speed sensors, throttle position sensors, and steering angle sensors, to determine when to engage the AWD. Upon sensing a need for extra traction, the ECU signals the transfer case to send power to the rear wheels. This engagement is virtually instantaneous, allowing the vehicle to regain traction and stability almost immediately. The transition is designed to be smooth and transparent to the driver, enhancing both safety and performance.
