Are Toyota 4runners All Wheel Drive
Most Toyota 4Runners come with a part‑time four‑wheel drive system, not full‑time all‑wheel drive, though some trims offer selectable AWD‑like modes. Understanding the drivetrain helps you choose the right 4Runner for off‑road capability, daily driving, and weather conditions.
When shoppers ask, “Are Toyota 4Runners all wheel drive?” they are usually trying to gauge how well the vehicle will handle rain, snow, or rugged trails. The answer is nuanced: the 4Runner lineup does not feature a traditional full‑time all‑wheel drive (AWD) system like many crossovers. Instead, Toyota equips most 4Runners with a part‑time four‑wheel drive (4WD) setup that drivers can activate when extra traction is needed. Understanding this distinction is key to picking the right trim and using the vehicle safely.
In this article we’ll break down the drivetrain options across the 4Runner model years, explain how 4WD differs from AWD, and show you when each system shines. We’ll also share practical tips for engaging and disengaging 4WD, maintaining the transfer case, and selecting tires that complement your driving style. By the end, you’ll know exactly whether a Toyota 4Runner meets your all‑weather or off‑road expectations.

Understanding the 4Runner Drivetrain Landscape
Toyota has built the 4Runner around a body‑on‑frame platform that emphasizes durability. Because of this architecture, the drivetrain choices are simpler than those found in unibody SUVs. Let’s explore the three primary configurations you’ll encounter.
Rear‑Wheel Drive (RWD) Base Models
The entry‑level 4Runner, often badged as the SR5 in earlier years, can be ordered with rear‑wheel drive only. In this configuration, power goes exclusively to the rear axle, which yields better fuel economy and a lighter feel on paved roads. RWD is perfectly adequate for city commuting and light highway cruising, especially if you live in a region with mild weather.
Even though RWD lacks the extra grip of driven front wheels, the 4Runner’s substantial weight distribution and robust suspension still provide decent stability. Many owners choose RWD when they plan to add aftermarket accessories like a lift kit or larger cargo box, knowing they won’t need the added complexity of a 4WD system.
Part‑Time Four‑Wheel Drive (4WD) – The Standard Offering
Most 4Runner trims, including the TRD Off‑Road, Limited, and higher‑end variants, come equipped with Toyota’s part‑time 4WD system. This setup features a two‑speed transfer case that lets the driver select between 2WD (high range), 4WD High (4Hi), and 4WD Low (4Lo). In 2WD mode the vehicle behaves like a rear‑wheel drive truck, while 4Hi sends power to both front and rear axles for improved traction on slippery surfaces. 4Lo multiplies torque for extreme off‑road situations such as rock crawling or deep sand.
Because the system is part‑time, you should avoid using 4Hi on dry pavement for extended periods; doing so can cause drivetrain binding and premature wear. Instead, engage 4WD only when the road surface is loose, snowy, muddy, or icy. For a quick refresher on the correct procedure, see the guide on how to put a Toyota 4Runner in 4 wheel drive.
Full‑Time All‑Wheel Drive (AWD) – Not Factory‑Standard
Unlike some Toyota SUVs such as the RAV4 or Highlander, the 4Runner does not offer a factory‑installed full‑time AWD system. AWD would automatically split torque between front and rear axles without driver intervention, providing seamless grip on wet roads. The absence of AWD means that if you want constant all‑wheel traction, you must rely on the part‑time 4WD system and manually shift into 4Hi when conditions deteriorate.
That said, many drivers find the part‑time approach perfectly acceptable because the 4Runner’s off‑road pedigree shines when you deliberately engage 4WD. The system’s simplicity also translates to fewer components that can fail, contributing to the vehicle’s legendary reliability.
All‑Wheel Drive vs. Four‑Wheel Drive: What’s the Difference?
Confusing AWD and 4WD is common, but the distinctions affect how you drive and maintain your 4Runner. Let’s clarify the core differences in plain language.

How Power Is Distributed
In an AWD system, a center differential (or an electronic clutch) continuously varies the torque split between front and rear axles. This happens automatically, often dozens of times per second, based on wheel slip sensors. The driver never needs to press a button or move a lever.
Conversely, a traditional 4WD system uses a mechanical transfer case with fixed gear ratios. When you select 4Hi, the transfer case locks the front and rear driveshafts together, delivering roughly equal torque to each axle. In 4Lo, the same lock occurs but with a lower gear ratio that multiplies torque for crawling over obstacles.
When Each System Excels
AWD shines on everyday roads where conditions change quickly—think rain‑slick highways, light snow, or gravel patches. Because it reacts instantly, you get improved stability without thinking about it.
4WD, especially the part‑time version in the 4Runner, is built for more demanding scenarios: deep snow, muddy trails, sandy beaches, and rocky inclines. The ability to lock the axles together prevents wheel slip that would otherwise leave you stuck. However, using 4Hi on dry pavement can cause tire scrub and stress the transfer case, which is why manufacturers recommend disengaging it as soon as traction improves.
Fuel Economy Implications
Because AWD systems are always active, they typically incur a small fuel‑penalty compared to a comparable 2WD vehicle. The 4Runner’s part‑time 4WD avoids this penalty when you stay in 2WD mode, giving you better mileage on long highway trips. When you do need 4WD, expect a modest drop in MPG, but the trade‑off is worth the added capability.
4Runner Trim Levels and Their Drivetrain Configurations
Toyota offers several trim levels across recent 4Runner generations (2010‑present). Knowing which trims come with which drivetrain helps you avoid surprises at the dealership.

SR5 (Base) – RWD Optional, 4WD Available
The SR5 trim can be ordered either as a rear‑wheel drive model or with the part‑time 4WD system. If you prioritize fuel efficiency and do not plan to tackle rough terrain, the RWD SR5 is a sensible pick. If you anticipate occasional snow or light off‑road use, opt for the SR5 with 4WD.
TRD Off‑Road – Standard 4WD with Off‑Road Enhancements
Every TRD Off‑Road 4Runner includes the part‑time 4WD system as standard, along with features like a locking rear differential, crawl control, and multi‑terrain select. This trim is aimed at enthusiasts who want serious trail capability without aftermarket modifications.
Limited – Luxury Meets 4WD
The Limited trim blends upscale interior appointments with the same part‑time 4WD found in the TRD Off‑Road. It adds leather‑trimmed seats, a premium audio system, and advanced safety tech while retaining full off‑road readiness.
Platinum and TRD Pro – Premium 4WD Packages
Higher‑end trims such as the Platinum and the TRD Pro also come with part‑time 4WD, but they add extra off‑road hardware (e.g., FOX shocks on the TRD Pro, upgraded skid plates, and unique wheel designs). These models are ideal if you want both luxury and hardcore trail performance.
Regardless of trim, the core drivetrain remains the same: a robust part‑time 4WD transfer case paired with a strong rear axle and an independent front suspension (on newer generations) or a solid front axle (on older models). This consistency simplifies parts sourcing and service.
Real‑World Performance: When AWD/4WD Makes a Difference
Understanding the mechanical bits is only half the story. Let’s look at concrete situations where the 4Runner’s drivetrain proves its worth—or where you might wish for a true AWD system.

Daily Commute in Wet Weather
On a rainy morning, the roads can become slick with standing water. In 2WD mode, the 4Runner’s rear wheels may lose traction under hard acceleration, especially if you have aggressive off‑road tires. Switching to 4Hi instantly sends power to the front axle, reducing the chance of wheel spin and improving stability. Many drivers report feeling more confident during sudden braking or cornering when 4WD is engaged.
If you live in an area with frequent light snow, using 4Hi during your commute can prevent the dreaded “fishtail” that rear‑wheel drive vehicles sometimes exhibit. Just remember to disengage 4WD once the pavement clears to avoid unnecessary wear.
Weekend Trail Adventures
When you head out to a forest service road that’s covered in loose gravel or mud, the 4Runner’s 4Low mode becomes invaluable. By locking the transfer case and lowering the gear ratio, you gain tremendous torque at low speeds, allowing you to crawl over rocks, logs, and steep inclines without stalling. The TRD Off‑Road’s electronically locking rear differential further ensures that both rear wheels turn together, preventing one wheel from spinning uselessly.
Experienced off‑roaders often pair 4Low with the crawl control feature (available on TRD Off‑Road and higher trims) to maintain a steady pace while focusing on steering. This combination lets you tackle challenging obstacles with less fatigue.
High‑Speed Highway Cruising
On long interstate stretches, keeping the 4Runner in 2WD mode yields the best fuel economy. The aerodynamic shape and relatively low rolling resistance of the stock tires contribute to respectable MPG figures for a body‑on‑frame SUV. Engaging 4WD at highway speeds offers no benefit and can actually increase drivetrain wear, so it’s best left disengaged.
Towing and Loaded Scenarios
When you’re towing a trailer or carrying a heavy payload, the extra traction from 4WD can help maintain stability, especially on wet ramps or uneven loading docks. The added front‑axle drive reduces the likelihood of the rear wheels pushing the trailer sideways. However, always verify that your trailer’s brakes are functional and that you’re within the vehicle’s Gross Combined Weight Rating (GCWR).
Maintenance Tips for Keeping the 4Runner Drivetrain Healthy
A well‑maintained drivetrain ensures that your 4Runner’s 4WD system works reliably when you need it most. Below are practical steps you can incorporate into your routine service schedule.
Check Transfer Case Fluid Regularly
The transfer case contains gears and chains that lubricate with specialized fluid. Toyota recommends inspecting the fluid level every 15,000 miles and changing it according to the maintenance schedule (often every 30,000‑50,000 miles, depending on driving conditions). Low or dirty fluid can cause noisy operation and premature wear.
If you frequently use 4Lo for rock crawling, consider shortening the interval because the transfer case seesaww. The transfer case endures higher loads in low range, which can degrade fluid faster.
Inspect Differentials and Seals
Both the front and rear differentials house gears that benefit from regular oil changes. Look for signs of leakage around the seals; a small drip can indicate a worn seal that needs replacement before contaminants enter the housing. Use the manufacturer‑specified gear oil (typically GL‑5 75W‑90) for optimal protection.
Exercise the 4WD System Periodically
Even if you rarely need 4WD, it’s wise to engage the system at least once a month. Shift into 4Hi, drive a short distance on a loose surface (like a gravel parking lot), then return to 2WD. This practice keeps the transfer case’s internal components lubricated and prevents seals from drying out.
Mind the Tires
Tire condition directly affects how well the 4WD system performs. Mismatched tire sizes or uneven tread wear can cause binding in the transfer case when 4WD is engaged. Always run the same tire size, load rating, and tread pattern on all four wheels. For all‑season confidence, many owners choose a set of highly rated all‑season tires; see our recommendations in the best all season tires for Toyota 4Runner guide.
Listen for Unusual Noises
Whining, clunking, or grinding noises when shifting into 4Hi or 4Lo can signal low fluid, worn bearings, or damaged chains. Address these symptoms promptly by visiting a qualified mechanic familiar with Toyota’s drivetrain.
Choosing the Right 4Runner for Your Needs
Now that we’ve covered the mechanics, maintenance, and real‑world usage, let’s synthesize the information into a buying guide. Your decision will hinge on how you plan to use the vehicle, your climate, and your comfort with manual drivetrain operation.
If You Prioritize Fuel Efficiency and Daily Commuting
Consider a rear‑wheel drive SR5 or a 4WD model that you keep in 2WD mode most of the time. The RWD variant saves a few hundred pounds and eliminates the transfer case’s parasitic loss, yielding better MPG. Pair it with a good set of all‑season tires for wet‑weather confidence.
If You Encounter Snow, Mud, or Light Off‑Road Regularly
Opt for any trim that includes part‑time 4WD (SR5 with 4WD, TRD Off‑Road, Limited, Platinum, or TRD Pro). Learn how to engage and disengage the system using the controls on the center console or steering wheel. Keep a set of all‑season or mild all‑terrain tires handy for transitional seasons.
If You Seriously Tackle Trails, Rocks, and Extreme Conditions
The TRD Off‑Road and TRD Pro trims are purpose‑built for this crowd. They feature locking differentials, enhanced suspension travel, skid plates, and aggressive tire options. Make sure to master the use of 4Low and crawl control, and invest in quality recovery gear (shackles, snatch strap, and a high‑lift jack).
If You Want Luxury Without Sacrificing Capability
The Limited and Platinum trims provide premium interiors while retaining the same robust 4WD system. You get leather, advanced infotainment, and driver‑assist features without giving up off‑road readiness.
Conclusion: Are Toyota 4Runners All Wheel Drive?
To answer the original question directly: Toyota 4Runners are not equipped with a traditional full‑time all‑wheel drive system. Instead, most models offer a part‑time four‑wheel drive setup that the driver can activate when extra traction is needed. A few base trims can be ordered with rear‑wheel drive only for those who prioritize fuel economy and everyday comfort.
Understanding this distinction lets you make an informed choice. If you need constant, automatic grip on wet roads, you might look toward a Toyota crossover with AWD. However, if you value rugged durability, the ability to lock axles for serious off‑road work, and the simplicity of a mechanical transfer case, the 4Runner’s part‑time 4WD is more than adequate—provided you use it correctly.
Remember to:
- Engage 4WD only when the road surface is loose, snowy, muddy, or icy.
- Disengage it as soon as you return to dry pavement to avoid drivetrain strain.
- Follow the maintenance schedule for transfer case and differential fluids.
- Keep tires matched and in good condition to maximize traction and prevent binding.
- Consult the how to get a Toyota 4Runner out of 4 wheel drive guide whenever you need to disengage the system safely.
With the right trim, proper tire selection, and a habit of exercising the 4WD system, your Toyota 4Runner will deliver dependable performance whether you’re navigating city streets, snowy highways, or backcountry trails. Happy driving!
