Understanding your drivetrain is the first step toward confident off-roading and proper vehicle maintenance.
I have spent years under the chassis of these Fords, and I promise to clarify the confusion surrounding these labels once and for all. This article provides a deep dive into drivetrain identification, common mechanical failures like PTU overheating, and how to maximize your traction on any surface.
We will preview the technical differences between traditional 4WD and modern Intelligent AWD systems found in newer models. You will also learn the specific physical signs to look for under your car and how to troubleshoot drivetrain malfunctions using basic DIY tools. Let’s get your Explorer ready for the trail.
Understanding the Basics: is the ford explorer 4wd or AWD?
The answer to the question is the ford explorer 4wd is often a matter of terminology used by Ford’s marketing department versus mechanical reality. Historically, older Explorers used a traditional 4WD system with a two-speed transfer case, allowing for a dedicated “Low” range for crawling over rocks.
Modern generations, specifically from 2011 to the present, typically utilize what Ford calls “Intelligent 4WD.” While the badge says 4WD, these systems operate more like a sophisticated All-Wheel Drive (AWD) setup that stays in front-wheel or rear-wheel drive until slip is detected.
The distinction is vital because a true 4WD system usually locks the front and rear axles together at a 50/50 power split. Modern Intelligent 4WD uses an electromagnetic clutch to vary torque, providing better fuel economy but requiring different maintenance habits than old-school gear boxes.
The Role of the Power Transfer Unit (PTU)
In front-wheel-drive-based Explorers (2011–2019), the PTU is the heart of the system that sends power to the rear wheels. It is a small gearbox bolted to the transmission that frequently runs hot due to its proximity to the exhaust manifold.
If you are pushing your Explorer off-road, the PTU fluid can break down quickly, leading to “AWD Off” messages on your dashboard. Checking this fluid is a proactive step every DIY mechanic should master to prevent a multi-thousand-dollar replacement bill.
How to Check Your Specific Drivetrain Configuration
If you are unsure if your specific unit is the ford explorer 4wd, the most reliable method is to look at the center console. Models equipped with extra traction capabilities will feature a Terrain Management System dial with icons for grass, gravel, snow, and mud.
You can also perform a visual inspection by sliding under the rear bumper with a flashlight to look for a rear differential. If you see a pumpkin-shaped metal housing with two axles extending to the wheels, your Explorer is sending power to the back.
Another “pro tip” is to check your VIN (Vehicle Identification Number) through an online decoder or at a local dealership. This will provide the original build sheet, confirming whether the vehicle left the factory as a 2WD, AWD, or 4WD variant.
Physical Components to Identify
- Front CV Axles: Look for rubber boots behind the front wheels; if they are present on a rear-drive-based 2020+ model, you have 4WD.
- Transfer Case: On older models (pre-2010), look for a secondary gearbox attached to the main transmission.
- Drive Shaft: Ensure there is a long, rotating shaft connecting the front engine area to the rear axle.
The Evolution of Explorer Drivetrains: Generation by Generation
The first and second generations of the Explorer were built on truck frames, making them rugged off-roaders with manual or electronic shift-on-the-fly 4WD. These models are favorites for DIYers because their locking hubs and transfer cases are straightforward to service.
The fifth generation (2011–2019) shifted to a unibody platform, where the question is the ford explorer 4wd became more complex. These models are primarily front-wheel drive but use the Intelligent 4WD system to engage the rear wheels only when necessary for stability.
The current sixth generation (2020–Present) returned to a rear-wheel-drive bias, which significantly improves towing and handling. This setup uses a longitudinal engine layout, allowing for a more robust 4WD system that feels more like a traditional truck when the going gets tough.
Key Differences in Handling
- 1st-4th Gen: Heavy, mechanical feel; excellent for deep mud and steep inclines.
- 5th Gen: Smooth, car-like handling; best for light trails and snowy highways.
- 6th Gen: Sporty and capable; balances high-speed towing with impressive articulation.
Managing the Terrain Management System (TMS) Like a Pro
When people ask is the ford explorer 4wd, they are often really asking if it can handle specific environments. The Terrain Management System (TMS) is the software brain that optimizes the engine, transmission, and braking to match the ground beneath you.
In “Sand Mode,” the system allows for more wheel spin and holds gears longer to maintain momentum in soft dunes. Conversely, “Deep Snow/Sand” mode softens throttle response to prevent the tires from digging a hole and getting the vehicle high-centered.
For the DIY enthusiast, understanding how to toggle these modes is as important as knowing how to change your oil. Using the wrong mode, such as “Mud/Ruts” on dry pavement, can put unnecessary stress on the CV joints and drivetrain components.
TMS Mode Breakdown
- Normal: Best for daily driving and maximum fuel efficiency.
- Trail: Optimizes traction for uneven dirt paths and forest roads.
- Slippery: Adjusts shifting to prevent fishtailing on icy or wet asphalt.
- Tow/Haul: Increases engine braking and adjusts shift points for heavy loads.
Common Drivetrain Problems and DIY Troubleshooting
One common issue that makes owners wonder is the ford explorer 4wd still working is the dreaded “AWD Fault” light. This often stems from a failed wheel speed sensor, which provides the computer with data on tire rotation speeds.
If one sensor fails, the computer disables the 4WD system to prevent mechanical damage, leaving you with only two-wheel drive. You can troubleshoot this at home using an OBD-II scanner with ABS capabilities to pinpoint exactly which wheel is causing the error.
Another frequent culprit is the clutch actuator inside the rear differential or PTU. If you hear a “clunking” sound during sharp turns, the clutches may be binding, which usually requires a fluid flush or a component replacement.
Troubleshooting Checklist
- Scan for Codes: Use a tool like FORScan to read Ford-specific drivetrain modules.
- Inspect Wiring: Check the harness leading to the rear differential for corrosion or trail damage.
- Check Fluid Levels: Ensure the PTU and rear diff are not leaking from the input shaft seals.
Maintenance Essentials for 4WD and AWD Explorers
To keep your drivetrain healthy, you must ignore the “Lifetime Fluid” claims often found in owner’s manuals. If you use your vehicle for heavy towing or off-roading, the heat generated will degrade the lubricants much faster than normal.
I recommend changing the PTU fluid every 30,000 miles, especially on 2011–2019 models that lack a drain plug. Many DIYers choose to drill and tap a small drain hole or use a vacuum pump to suck the old oil out through the fill port.
The rear differential fluid should also be swapped periodically to remove metal shavings that naturally accumulate during the break-in period. Using a high-quality 75W-140 synthetic gear oil can significantly extend the life of your bearings and gears.
Recommended Tools for Drivetrain DIY
- Fluid Transfer Pump: Essential for filling differentials in tight spaces.
- 10mm & 12mm Sockets: Common sizes for drain and fill plugs on Ford SUVs.
- Torque Wrench: Vital for ensuring drain plugs are tightened to spec without stripping threads.
Frequently Asked Questions About is the ford explorer 4wd
How do I know if my Ford Explorer is 4WD or 2WD?
The easiest way is to look for a drive shaft going to the rear wheels and a control dial on the console. If your dash shows a “Power Split” screen in the menu options, your vehicle is actively sending power to all four wheels.
Can I drive my Ford Explorer 4WD on dry pavement?
Yes, modern Explorers use an “Intelligent” system that automatically disconnects or varies power to prevent driveline bind. Unlike old trucks, you do not need to manually disengage the system when you hit the highway.
Does 4WD use more gas than 2WD?
Generally, yes, because of the parasitic loss from turning extra gears and the added weight of the transfer case. However, modern Fords can disconnect the front axle when not needed to save fuel during cruising.
What does the “AWD Off” light mean?
This light typically indicates that the PTU has overheated or a sensor has failed. The vehicle will default to two-wheel drive to protect the mechanical components from further damage until the system cools down.
Future Trends: The Shift Toward Electric 4WD
As we look toward the future, the question of is the ford explorer 4wd will involve electric motors rather than mechanical drive shafts. The Explorer EV and hybrid models use electric motors on the axles to provide instantaneous torque and traction.
This shift eliminates the need for a PTU or a traditional transfer case, reducing the number of moving parts that can fail. For the DIY mechanic, this means a shift from changing gear oil to managing high-voltage cooling systems and software updates.
Regardless of the technology, the goal remains the same: providing the grip you need to explore the great outdoors safely. Keep your fluids fresh, your sensors clean, and your tires aired up for the best experience.
Understanding your drivetrain allows you to push your vehicle to its limits without breaking it. Whether you are navigating a blizzard or a muddy trail, knowing your Explorer’s capabilities is the ultimate tool in your kit. Stay safe, keep wrenching, and enjoy the ride!
