The Complete Overview of How to Put a Ford Explorer in 4 Wheel Drive
The Ford Explorer’s 4WD system isn’t a one-size-fits-all solution—it evolves with each generation. Older models (pre-2011) relied on a **mechanical transfer case** with a traditional four-position selector (2H, 4H, 4L, N), while newer models (2020+) integrate **electronic engagement** via the **FordCo** infotainment system or a dedicated button. The shift reflects Ford’s move toward **auto-select 4WD**, where the system automatically adjusts torque distribution based on wheel slip. However, this convenience comes with trade-offs: drivers lose manual control, and the system may hesitate in critical moments. Understanding your Explorer’s specific setup is the first step in **how to put it in 4WD** without risking mechanical failure. The process also varies by trim level. The **Platinum and Limited** trims, for instance, often include **terrain management modes** (Mud/Snow, Rock Crawl, Sand) that adjust throttle response and suspension settings alongside 4WD engagement. Meanwhile, base models might lack these features, relying solely on the driver’s judgment. Missteps here—like engaging 4WD while the vehicle is in motion—can overwhelm the drivetrain, leading to premature wear or even failure. The key is patience: **4WD is for low-speed, high-traction scenarios**, not a substitute for proper driving technique. Whether you’re tackling a snowbank or navigating a rocky trail, the Explorer’s system is a tool, not a crutch.Historical Background and Evolution
The Ford Explorer’s foray into 4WD began in the late 1990s with the **X-Trac transfer case**, a robust but mechanically complex system that required manual shifting. Early models used a **part-time 4WD** setup, meaning the driver could disengage the front axle when not needed to reduce wear. This design was borrowed from commercial trucks, where durability outweighed convenience. By the 2000s, Ford introduced **full-time AWD** in some trims, blending the best of both worlds: permanent front-wheel engagement for stability and optional 4WD for off-road capability. However, the transition wasn’t seamless—many owners complained about **vague shift points** and **unpredictable engagement**, leading to a reputation for complexity. The turning point came with the **2020 Explorer redesign**, which adopted a **new electronic 4WD system** paired with the **10-speed automatic transmission**. This shift eliminated the traditional transfer case lever, replacing it with a **digital selector** accessible via the touchscreen or a dedicated button. The system now features **auto-select 4WD**, where the vehicle automatically engages 4WD if it detects wheel slip. While this reduces driver error, it also removes the tactile feedback of manual shifting. Critics argue that the loss of control in extreme conditions—like deep mud or steep climbs—is a step backward. Yet, Ford’s rationale is clear: **safety and simplicity** over raw off-road capability. The result is a system that’s easier to use but demands a different skill set for serious off-roaders.Core Mechanisms: How It Works
At its core, the Ford Explorer’s 4WD system relies on a **transfer case** that splits engine power between the front and rear axles. In **2H (2-High) mode**, power is sent only to the rear wheels, ideal for dry pavement. When shifted to **4H (4-High)**, the transfer case engages the front axle at a **50/50 torque split**, providing better traction without locking the differentials. This is the preferred setting for **light off-road conditions** like snow or gravel. For more demanding terrain, **4L (4-Low)** reduces the gearing, increasing torque but limiting top speed—critical for steep hills or deep ruts. The **N (Neutral)** position disengages the transfer case entirely, useful for towing or repairs. Modern Explorers (2020+) replace the mechanical lever with an **electronic system** that communicates with the transmission and stability control. When **4WD is selected**, the vehicle monitors wheel speed and automatically adjusts torque distribution to prevent wheel spin. However, this isn’t true **locking differential 4WD**—it’s **open differential AWD** with enhanced traction control. For true off-road capability, owners often retrofit **locking differentials** or **derision systems**, though Ford doesn’t offer these as OEM options. The trade-off is a system that’s **safer for daily driving** but less capable in extreme conditions compared to dedicated 4WD trucks like the Ford F-150 Raptor.Key Benefits and Crucial Impact
Engaging 4WD in a Ford Explorer isn’t just about conquering rough terrain—it’s about **preserving the drivetrain** and **enhancing safety** in unpredictable conditions. The system’s ability to **distribute power dynamically** reduces the risk of getting stuck, whether you’re plowing through snow or climbing a rocky incline. Yet, the benefits extend beyond off-road adventures: in **icy or slushy urban environments**, 4WD provides the confidence to navigate without skidding. The downside? **Increased fuel consumption** and **higher maintenance costs** due to the added complexity of the transfer case and differentials. Still, for those who frequently encounter **low-traction scenarios**, the trade-off is worthwhile. The Explorer’s 4WD system also reflects Ford’s broader strategy to **blend SUV practicality with light off-road capability**. Unlike dedicated 4WD trucks, the Explorer prioritizes **comfort and efficiency**, making it a versatile choice for families who still want adventure. However, this comes with a learning curve—**how to put it in 4WD correctly** is non-negotiable. One misstep, such as engaging 4WD while moving at speed, can damage the transfer case or even the transmission. The system is designed to **prevent this**, but it’s not foolproof. Understanding the **limits of your Explorer’s 4WD**—and when to disengage—is the difference between a smooth off-road experience and a costly repair.*"4WD isn’t a magic bullet—it’s a tool that demands respect. Too many drivers treat it like a switch for better handling, not a system for specific conditions."* — **Ford Off-Road Training Manual, 2023**
