AWD Towing: Why Two Wheels Down Destroys Drivetrains

I've been driving a tow truck and dispatching in Nashville for over a decade. In that time, I've seen just about every way a car can break down. But the most gut-wrenching calls aren't the dramatic winch-outs from a ditch off Briley Parkway; they're the ones that start weeks after a tow. A customer calls, their voice tight with stress, and says, "My car started making a grinding noise after it was towed last month. Now the mechanic says I need a new transmission."

That's when I ask the question I already know the answer to: "Was your vehicle towed with two wheels on the roadway?" The silence on the other end of the line says it all. That one mistake, made in the heat of the moment on the side of I-40, just cost them thousands of dollars. It's a completely avoidable disaster, and I'm going to tell you exactly how to prevent it from ever happening to you.

How One Tow Can Destroy Your Drivetrain

If you own an all-wheel drive (AWD) vehicle—a Subaru, an Audi Quattro, a Toyota RAV4 AWD, most modern SUVs—your car is built on a simple principle: all four wheels work together. The engine sends power through a complex system of differentials and a transfer case to make sure all four wheels are spinning at coordinated speeds. It's a beautiful system when it's working right.

But when you tow it with two wheels lifted and two on the ground, you create a mechanical nightmare.

The wheels on the pavement are spinning at 60 mph. The wheels on the tow truck's lift are sitting still. Your car's transfer case and center differential, the "brains" of the AWD system, are caught in the middle. They frantically try to make sense of this impossible input, sending power back and forth between axles that are spinning at wildly different speeds.

Without the engine running, there's no hydraulic pump circulating lubricating fluid. Within minutes, this intense friction generates incredible heat. Bearings start to scream, gears begin to grind, and delicate clutch packs inside the transmission overheat and warp. Damage isn't a possibility; it's a certainty. And it starts happening in the first mile.

The Expensive Parts That Get Fried

When a customer gets hit with a repair bill from an improper tow, it's usually for one or all of these components. This isn't theoretical; this is what we see on shop estimates every month.

• The Transfer Case: This is ground zero for the damage. It’s what splits power between the front and rear axles. When it’s forced to reconcile a massive speed difference, the internal chain can stretch or snap, and the viscous coupling can cook itself solid. Replacement cost: $2,000 - $4,500.
• The Center Differential: Housed within the transfer case or transmission, this unit allows for slight speed differences between the axles when turning. Forcing it to handle a 60 mph vs. 0 mph difference can strip its gears or weld them together. Repair cost: $1,500 - $3,000.
• The Transmission: Even if the transfer case takes the initial hit, the transmission is directly connected. With no fluid circulating, its own internal clutches and bearings are spinning dry. After just a few miles down I-24, you're looking at catastrophic failure. This is the big one. Replacement cost: $4,000 - $9,000.

Add it all up, and a single cheap tow from an inexperienced company can easily lead to a repair bill that exceeds the value of the car. I’ve seen a bill for over $12,000 on a newer luxury SUV that was dragged just from Bellevue to a dealership downtown.

Which Vehicles Are Most at Risk?

You might think this only applies to high-end European cars, but this problem affects a huge number of vehicles on the road today. If you're not sure, it's always safer to assume your car needs special handling.

• Full-Time AWD: These systems are always engaged and are the most vulnerable. This includes every Subaru with Symmetrical AWD, Audi's Quattro system, BMW's xDrive, and Mercedes-Benz's 4MATIC. There is no button to push or switch to flip to make them "2WD." They must have all four wheels off the ground.
• Part-Time or "On-Demand" AWD: This is common in many crossovers and SUVs like the Honda CR-V, Ford Escape, and Chevy Equinox. While they primarily drive the front wheels, the rear wheels can engage automatically without warning, especially when the front wheels are lifted and not spinning. The risk is just as high.
• 4-Wheel Drive (4WD): Trucks and SUVs like the Ford F-150 4x4 or Jeep Wrangler have a selectable system. Even if you put it in 2WD mode, towing it with the rear wheels on the ground and the front wheels stationary can still cause damage to the transfer case if the hubs are locked. Towing with the drive wheels on the ground is always a gamble.

The manufacturer's owner's manual is the ultimate authority. Subaru explicitly warns that towing with any wheels on the ground will cause "serious damage to the transmission." BMW and Audi are even more direct: xDrive and Quattro vehicles must be transported on a flatbed. Period.

The DIY Towing Trap

Sometimes, the bad tow isn't from a cut-rate company; it's a well-intentioned friend with a truck and a tow strap. This is another common path to the same five-figure repair bill, often with added dangers. Trying to pull a disabled vehicle with a strap from, say, a tight spot in Donelson to a shop in Hermitage seems simple, but it combines all the worst-case scenarios.

First, your disabled car has no power brakes and no power steering. You have to stomp on the brake pedal with all your might to get it to slow down, and turning the wheel is a full-body workout. I’ve cleaned up accidents on Nolensville Pike where the towed car, unable to stop, rolled right into the back of the truck that was supposed to be saving it.

Second, those yellow nylon straps are not designed for this. When they snap under the immense tension of pulling a 4,000-pound vehicle, they recoil with explosive force. I've seen one shatter a truck's rear window. The attachment points—a bumper cover or a cosmetic "tow hook"—can also rip right off the car, sending metal flying.

Finally, and most relevant to this article, it almost always involves towing the vehicle with its drive wheels on the ground. Whether it's a front-wheel-drive car being pulled from the front or an AWD vehicle being pulled from any direction, you're spinning parts of the drivetrain that have no lubrication. You might save $150 on a professional tow only to inflict $5,000 in damage to your transmission. It's a terrible bet to make.

If your car won't start but you just have a dead battery or an empty fuel tank, you don't even need a tow. A simple call for basic roadside help can get you going again without ever moving the car.

An Operator's Log: What a Pro Knows

When you call a reputable towing company, the dispatcher's first questions should be, "What year, make, and model is the vehicle?" and "Is it all-wheel drive?" Your answer determines everything. It tells us whether to send a standard wheel-lift truck for a simple FWD car or to dispatch a flatbed. If a company just says "we're sending a truck" without asking for details, that's a huge red flag.

Here’s another insider detail: even with a flatbed, some situations require special gear. If an AWD vehicle is stuck in Park and won’t shift to Neutral (due to electrical failure or transmission damage), we can't just drag it onto the flatbed. That would scrape the tires and potentially damage the parking pawl in the transmission. Instead, we use a set of "skates" or dollies—small, wheeled platforms that we place under each locked wheel. This allows the car to roll freely up onto the flatbed without any part of its own drivetrain moving. A driver who doesn't have skates and suggests just "yanking it up" is a driver you should send away.

Spotting a Bad Tow Before It Happens

Protecting your vehicle starts with you. Before a hook is ever attached, ask these questions:

1. "My car is all-wheel drive. Did you bring a flatbed?" If the answer is no, and they try to tell you it's fine, they are wrong.
2. "Can you guarantee all four wheels will be off the ground for the entire tow?" This is the only acceptable method.
3. "Are you able to handle a car that's stuck in Park without dragging it?" This shows you understand the process and tests their knowledge.

If the operator dismisses your concerns, tells you "short distances are okay," or acts annoyed by your questions, refuse the service. Tell them to leave. A few minutes of awkwardness is infinitely better than a destroyed car. Waiting an extra 30 minutes for the right truck to arrive from across town is the smartest thing you can do.

The Only Safe Way: Flatbed First

For any AWD or 4WD vehicle, there is only one universally safe and manufacturer-approved method of towing: a flatbed tow truck. Your entire vehicle—all four wheels—is loaded onto the bed of the truck. The drivetrain is completely stationary. There is zero risk of the damage we've been discussing. It’s the gold standard for a reason.

Yes, a flatbed tow might cost slightly more than a conventional wheel-lift tow. But that extra $50 is the best insurance policy you will ever buy for your car's drivetrain. When you call for service, specifically request a flatbed and mention that your vehicle is all-wheel drive. We get these calls all day long at Hook Em' Up Towing on our (615) 756-5330 line, and we always send the right equipment the first time.

When Your Warranty Won't Help You

Here's the final, brutal truth. If your car is damaged because it was towed improperly, your vehicle's manufacturer warranty will not cover the repairs. The owner's manual clearly states the correct towing procedure. By allowing an improper tow, you've voided that part of the warranty coverage. Your car insurance might cover it, but you'll likely have to file a claim against the tow company's liability insurance, which can be a long, frustrating process. You’re left in the middle, often without a car for weeks, fighting to get someone else to pay for a mistake you could have prevented.

From the tight corners on Music Row to the high-speed merges on the I-24/I-40 split, a breakdown in Nashville puts you under pressure. It’s tempting to take the first truck that shows up. Don't do it. The difference between a routine tow and a financial catastrophe for your AWD vehicle comes down to a single, simple action: making sure all four wheels are up.
