Ready to learn the ins and outs of safely moving your RWD vehicle? Let’s dive in.
Understanding Your RWD Drivetrain Before You Tow
Before you even think about connecting a tow strap, it’s crucial to understand what makes a rear-wheel drive vehicle tick. This knowledge is key to preventing expensive mistakes.
In a RWD car, power from the engine is sent to the rear wheels via a transmission and a driveshaft. The driveshaft connects the transmission to the differential, which then distributes power to the rear wheels.
When the rear wheels are on the ground and spinning during a tow, they turn the driveshaft. This, in turn, spins components inside the transmission.
The Risk to Your Transmission
The primary concern when towing a RWD vehicle with its drive wheels on the ground is the transmission. Automatic transmissions rely on a pump to circulate fluid, lubricating and cooling their internal components.
When the engine is off, this pump isn’t operating. If the driveshaft is spinning the transmission, these internal parts are rotating without proper lubrication.
This lack of lubrication generates immense heat and friction. It can quickly lead to severe wear, burning up clutches, and ultimately, a destroyed transmission.
Differential Considerations
While less common than transmission damage, the differential also sees activity when the rear wheels spin. Most modern differentials are designed to handle some rotation without power, but prolonged, high-speed towing can still cause issues, especially if fluid levels are low.
Understanding these risks highlights why simply hooking up a tow strap and dragging a RWD car by its front end is a recipe for disaster. Proper preparation or the right towing method is essential.
Choosing the Right Towing Method for Your RWD Vehicle
Selecting the correct towing method is paramount when considering how to tow a RWD car without damaging it. There are several options, each with its own advantages and disadvantages.
Your choice will depend on the distance, your equipment, and the type of RWD vehicle you’re towing.
Flatbed Trailer: The Safest Bet
For any RWD vehicle, a flatbed trailer is always the safest and most recommended option. This method involves loading the entire vehicle onto a trailer, lifting all four wheels off the ground.
- Pros: Eliminates all risk of drivetrain damage, suitable for any distance or speed, provides maximum stability.
- Cons: Requires a larger tow vehicle, a flatbed trailer, and more skill to load and secure the vehicle properly.
If you have access to a flatbed and a capable tow rig, this should be your first choice, especially for longer hauls or valuable vehicles.
Tow Dolly: A Common DIY Solution
A tow dolly lifts only one axle of the towed vehicle off the ground. For RWD cars, this means lifting the drive wheels (the rear wheels) off the ground.
The front wheels of the RWD car remain on the ground, allowing it to steer behind the tow vehicle.
- Pros: More affordable and easier to store than a flatbed, doesn’t require removing the driveshaft, good for moderate distances.
- Cons: Can be less stable than a flatbed, requires proper loading and securing, often has weight limitations.
This is a popular choice for many DIYers needing to tow a RWD car, provided it’s set up correctly.
Tow Bar: Generally Not Recommended for RWD
A tow bar connects directly to the front frame of the towed vehicle, allowing all four wheels to remain on the ground. The towed vehicle essentially “follows” the tow rig.
- Pros: Relatively simple setup once installed, minimal equipment needed.
- Cons: Puts the RWD vehicle’s rear wheels on the ground, meaning the driveshaft and transmission will be rotating without lubrication.
Using a tow bar for a RWD vehicle almost always requires disconnecting the driveshaft or removing the rear axles. Without these modifications, you risk severe drivetrain damage. This method is generally only suitable for very short distances at low speeds, or if specific vehicle modifications are made.
Pre-Towing Checklist: Essential Steps for RWD Vehicles
No matter which towing method you choose, a thorough pre-towing inspection and preparation are critical. Skipping these steps can lead to accidents or vehicle damage.
Vehicle Inspection Basics
- Check Tires: Ensure all tires on both the tow vehicle and the RWD car are properly inflated and in good condition. Look for any bulges, cuts, or excessive wear.
- Fluid Levels: Verify brake fluid, power steering fluid, and coolant levels in both vehicles. Low fluids can cause issues during towing.
- Lights and Signals: Test all brake lights, turn signals, and running lights on both vehicles. You’ll need an auxiliary lighting kit for the towed vehicle if its lights aren’t visible or operational.
- Brakes: Ensure the brakes on both vehicles are in good working order. Remember, the towed vehicle adds significant weight, increasing stopping distances.
Specific RWD Considerations
If you’re using a tow dolly and the rear wheels will be on the ground (i.e., you’re towing a FWD car, not a RWD car, with its front wheels on the dolly), you might need to address the transmission. But since we’re discussing how to tow a RWD car, the rear wheels are the drive wheels.
- Automatic Transmissions: If towing a RWD vehicle with its rear wheels on the ground (e.g., with a tow bar), you absolutely must disconnect the driveshaft. This prevents the transmission from spinning without lubrication. If you cannot disconnect the driveshaft, a flatbed or a tow dolly (lifting the rear wheels) is the only safe option.
- Manual Transmissions: Manual transmissions generally handle towing with the drive wheels on the ground better than automatics, as they don’t rely on a fluid pump in the same way. However, it’s still best practice to place the transmission in neutral and, for longer distances, consider disconnecting the driveshaft to prevent unnecessary wear.
- Parking Brake: Ensure the parking brake on the towed RWD vehicle is fully disengaged before towing.
Always consult your vehicle’s owner’s manual for specific towing recommendations. Some manufacturers have very strict guidelines or prohibit certain towing methods.
Step-by-Step Guide: How to Tow a RWD Car with a Dolly
Towing a rear-wheel drive vehicle using a tow dolly is a common and effective method for DIYers. This guide focuses on lifting the rear (drive) wheels onto the dolly.
This is the correct approach to prevent transmission damage.
1. Prepare Your Tow Vehicle and Dolly
- Hitch Up: Securely attach the tow dolly to your tow vehicle’s hitch receiver. Ensure the hitch ball is the correct size and the coupler is fully latched. Insert the safety pin.
- Safety Chains: Cross and attach the dolly’s safety chains to the tow vehicle’s frame or hitch.
- Lights: Connect the dolly’s wiring harness to your tow vehicle’s trailer light connector. Test brake lights, turn signals, and running lights.
- Tire Pressure: Check the tire pressure on the tow dolly. Proper inflation is crucial for stability.
2. Position the RWD Vehicle
- Line Up: Carefully back the tow vehicle and dolly up to the RWD car. You want to position the dolly’s ramps directly in front of the RWD car’s rear wheels.
- Straighten Wheels: Ensure the RWD car’s front wheels are straight and the steering wheel is unlocked.
3. Load the RWD Car Onto the Dolly
- Drive On: Slowly and carefully drive the RWD car onto the dolly ramps until the rear wheels are centered and seated in the dolly’s cradles. Have a spotter guide you.
- Secure Parking Brake: Once loaded, engage the RWD car’s parking brake.
- Transmission: Place the RWD car’s transmission in Park (for automatic) or in gear (for manual) after the wheels are secured. This prevents accidental rolling off the dolly.
4. Secure the RWD Vehicle
- Wheel Straps: Use the heavy-duty wheel straps provided with the dolly. Thread them over the rear tires and tighten them securely. Ensure they are snug and the tires are firmly seated.
- Safety Chains: Attach additional safety chains from the dolly to the RWD car’s rear axle or a strong frame point. These are backup in case the wheel straps fail.
- Front Wheels: Ensure the RWD car’s front wheels are straight and the steering wheel is unlocked. Some recommend using a steering wheel lock or bungee cords to keep it centered, but generally, if the front wheels are straight, the vehicle will track properly.
5. Final Check and Test Drive
- Double-Check Everything: Re-verify all connections, straps, chains, and lights.
- Release Parking Brake: Disengage the RWD car’s parking brake before you start driving.
- Short Test Drive: Drive a short distance (e.g., 5-10 minutes) and then pull over. Re-check all straps and connections. Straps can sometimes loosen after initial movement.
This careful approach ensures your RWD vehicle is safely secured for the journey.
Safety First: Crucial Towing Precautions
Towing, especially with a heavy vehicle, requires heightened awareness and adherence to safety protocols. These precautions apply regardless of how to tow a RWD car.
Understand Your Weight Limits
- Tow Vehicle Capacity: Never exceed your tow vehicle’s Gross Vehicle Weight Rating (GVWR) or its maximum towing capacity. This includes the weight of the trailer/dolly and the towed vehicle.
- Tongue Weight: Ensure the tongue weight (the downward force on your hitch) is within the recommended range (typically 10-15% of the total trailer weight). Improper tongue weight can lead to severe instability.
- Dolly Capacity: Verify the tow dolly’s weight capacity is sufficient for your RWD car.
Driving Adjustments
- Slower Speeds: Drive slower than usual. Towing significantly increases your stopping distance and reduces maneuverability.
- Wider Turns: Take wider turns to avoid clipping curbs or other obstacles with the towed vehicle.
- Increased Stopping Distance: Anticipate stops much earlier than you normally would. Your combined rig is much heavier.
- Check Mirrors Frequently: Constantly monitor your mirrors to ensure the towed vehicle is tracking correctly and there are no issues.
- Avoid Sudden Movements: Smooth acceleration, braking, and steering are crucial to maintaining control and preventing sway.
Environmental Awareness
- Weather Conditions: Be extra cautious in adverse weather. Rain, snow, or high winds can make towing extremely dangerous. Consider postponing if conditions are severe.
- Road Conditions: Watch for potholes, bumps, or uneven surfaces that could destabilize your setup.
- Long Descents: Use lower gears on long descents to allow your engine to assist in braking. This prevents your brakes from overheating.
Remember, safety isn’t just a suggestion; it’s a requirement when you’re moving heavy equipment. Don’t take chances.
Common Mistakes to Avoid When Towing a RWD Vehicle
Even experienced DIYers can fall victim to common towing errors. Being aware of these pitfalls will help you avoid costly mistakes when learning how to tow a RWD car.
1. Towing with Drive Wheels on the Ground (Automatic Transmission)
This is arguably the biggest and most expensive mistake. Towing an automatic RWD vehicle with its rear wheels on the ground, without disconnecting the driveshaft, will almost certainly destroy the transmission due to lack of lubrication.
2. Exceeding Weight Capacities
Overloading your tow vehicle or tow dolly is incredibly dangerous. It can lead to loss of control, brake failure, tire blowouts, and severe accidents. Always know and respect your equipment’s limits.
3. Improperly Secured Vehicle
Loose straps, chains, or an unsecured steering wheel can cause the towed vehicle to shift, sway, or even detach. Double-check all connections before and during your trip.
4. Incorrect Tire Pressure
Underinflated tires on either the tow vehicle, dolly, or towed vehicle can lead to instability, increased rolling resistance, excessive heat buildup, and potential blowouts.
5. Forgetting the Parking Brake (on the dolly) or Leaving it Engaged (on the car)
Leaving the parking brake on the RWD car engaged while towing will cause significant friction and damage. Conversely, forgetting to engage it while loading/unloading can lead to the vehicle rolling off the dolly.
6. Ignoring Vehicle Manuals
Manufacturers often have specific towing instructions or warnings for their vehicles. Always consult the owner’s manual for both the tow vehicle and the vehicle being towed.
7. Not Practicing
If you’re new to towing, practice in an empty parking lot. Get a feel for how the rig handles, turns, and brakes before hitting the open road.
When to Call a Professional Tow Service
While we champion the DIY spirit at FatBoysOffroad, there are definitely times when it’s smarter, safer, and ultimately more cost-effective to call in the professionals.
Knowing your limits is a mark of true expertise, especially when it comes to something as critical as knowing how to tow a RWD car.
Complex Drivetrain Configurations
If your RWD vehicle has a complex drivetrain (e.g., some performance cars, classic vehicles, or modified off-road rigs with custom differentials), it might be safer to let a professional handle the tow. They have specialized equipment and knowledge.
Long Distances or Difficult Terrain
For very long hauls (hundreds of miles) or if you’re recovering a vehicle from challenging off-road terrain, a professional service is usually the best choice. They have the right heavy-duty equipment for recovery and long-distance transport.
No Access to Proper Equipment
If you don’t have a suitable tow vehicle, a flatbed trailer, or a properly sized tow dolly, don’t try to make do with inadequate equipment. The risks far outweigh the cost of a professional tow.
Uncertainty or Lack of Experience
If you’re unsure about any aspect of the towing process, from securing the vehicle to understanding weight distribution, it’s best to err on the side of caution. A professional tow truck operator has the experience to ensure a safe transport.
Vehicle Damage or Immovable Parts
If the RWD vehicle has sustained significant damage, has seized wheels, or is otherwise in a state that makes safe loading difficult, a professional service with a winch and specialized recovery tools is necessary.
Don’t let pride get in the way of safety. Professional tow services are equipped and insured to handle these situations, providing peace of mind.
Frequently Asked Questions About Towing a RWD Car
Can I tow a RWD automatic car with all four wheels on the ground?
No, not without risking severe transmission damage. The rear wheels, being the drive wheels, will spin the transmission without lubrication. You must either disconnect the driveshaft or lift the rear wheels off the ground using a flatbed or tow dolly.
What’s the difference between towing a RWD and FWD car?
The main difference lies in which wheels are the “drive wheels.” For a Front-Wheel Drive (FWD) car, you’d typically use a tow dolly to lift the front wheels. For a Rear-Wheel Drive (RWD) car, you must lift the rear wheels to prevent drivetrain damage, or use a flatbed for either.
Do I need to put the RWD car in neutral when towing?
If you are towing with the rear (drive) wheels on the ground (which is generally not recommended for RWD unless the driveshaft is disconnected), putting it in neutral is crucial for manual transmissions. For automatic RWD cars, if the driveshaft is disconnected, the transmission can be in park. If the rear wheels are off the ground (e.g., on a dolly or flatbed), the transmission can be in park for security.
How do I know my tow vehicle can handle the weight of my RWD car?
Check your tow vehicle’s owner’s manual for its maximum towing capacity and Gross Vehicle Weight Rating (GVWR). Also, check the Gross Axle Weight Ratings (GAWR). Compare these figures to the weight of your RWD car plus the tow dolly or trailer. Never exceed these ratings.
Can I tow a RWD car with a regular rope or chain?
Using a regular rope or chain for towing is highly discouraged and often illegal. These methods offer no controlled braking or steering for the towed vehicle, making them extremely dangerous. Always use proper towing equipment like a tow bar, tow dolly, or flatbed trailer with appropriate safety chains and lighting.
Conclusion
Successfully navigating how to tow a RWD car comes down to understanding your vehicle’s mechanics, choosing the right equipment, and prioritizing safety above all else. Whether you opt for the ultimate security of a flatbed trailer or the practicality of a tow dolly, careful preparation is your best friend.
Always double-check your connections, respect weight limits, and drive with extra caution. Remember that a little extra time spent on preparation can save you thousands in potential repairs and keep you safe on the road.
Empower yourself with this knowledge, and you’ll be ready for whatever the road throws your way. Stay safe, stay smart, and keep those wheels turning!
