Bypassing the electronic safety features requires a specific sequence for towing a Jeep Wrangler. If you own a Wrangler and need to tow it behind a motorhome or on a trailer, you have to know exactly how to tow Jeep Wrangler models without damaging the transmission or transfer case.
Towing a Jeep Wrangler is not like towing a standard car. The Wrangler has a unique drivetrain that demands careful preparation. Flat towing (also called dinghy towing) is popular because the Wrangler can be towed with all four wheels on the ground. But you must follow the steps exactly.
This guide covers everything from transfer case settings to wiring a tow bar. You will learn the safe method for both manual and automatic transmissions. Let’s get started.
Understanding Towing Basics For Jeep Wrangler
Before you hook up any equipment, you need to understand how the Wrangler’s drivetrain works. The transfer case has a neutral position that disconnects the front and rear axles from the transmission. This allows the wheels to spin freely without turning the transmission internals.
If you skip the neutral step, you risk destroying the transmission. Automatic transmissions are especially vulnerable because they rely on fluid circulation. Towing with the transfer case in gear will starve the transmission of lubrication.
Manual transmissions are slightly more forgiving but still require the transfer case in neutral. Never tow a Wrangler with the transfer case in 2H, 4H, or 4L.
Flat Towing Vs Trailer Towing
Flat towing means the Wrangler’s wheels stay on the ground. You connect a tow bar from the motorhome to the Wrangler’s front bumper. This is the most common method for RV owners.
Trailer towing means you load the Wrangler onto a flatbed or car trailer. This method is safer for long distances but requires more equipment and storage space. Both methods work, but flat towing is more convenient for daily use.
Your choice depends on your RV setup and how often you plan to tow. Flat towing is simpler for short trips, while trailer towing offers more protection for the vehicle.
How To Tow Jeep Wrangler: Step-By-Step Instructions
Now we get into the core procedure. Follow these steps exactly to avoid damage. The process works for all Wrangler models from 1997 to present, including the JL and JK generations.
Step 1: Park On Level Ground
Find a flat surface before you start. This ensures the transfer case shifts into neutral properly. If the vehicle is on a slope, the internal gears may bind and prevent smooth engagement.
Turn off the engine. Set the parking brake firmly. You don’t want the vehicle rolling while you work underneath.
Step 2: Shift The Transmission
For automatic transmissions, shift into Park (P). For manual transmissions, shift into Neutral. This step is important because it allows the transmission output shaft to spin freely.
Some owners skip this step, but it is required for the transfer case to disengage properly. The transmission must be in the correct position before you move the transfer case lever.
Step 3: Move The Transfer Case To Neutral
Locate the transfer case shifter. On most Wranglers, it is a separate lever next to the main shifter. If you have a JL model with a push-button transfer case, you use the rotary dial.
For manual lever: Pull the lever down through 4H and into N (Neutral). You will feel a detent. The lever should sit in the neutral gate. For rotary dial: Turn the dial to N. The display will show “NEUTRAL” on the instrument cluster.
Verify neutral by trying to roll the vehicle slightly. If the wheels move freely, you are in neutral. If they resist, the transfer case is still engaged.
Step 4: Release The Parking Brake
Once the transfer case is in neutral, release the parking brake. The vehicle should now roll freely. If it does not, recheck the transfer case position.
Leave the transmission in Park (automatic) or Neutral (manual). The transfer case neutral position isolates the transmission from the wheels.
Step 5: Connect The Tow Bar
Attach the tow bar to the Wrangler’s front frame horns. Most aftermarket tow bars use a crossbar that bolts to the frame. You may need a base plate kit for your specific model year.
Connect the safety chains. Cross them under the tow bar to create a cradle. This catches the Wrangler if the main connection fails.
Plug in the wiring harness. This connects the Wrangler’s tail lights to the motorhome’s electrical system. Test all lights before you drive away.
Step 6: Check Everything
Walk around the vehicle. Confirm the tow bar pins are fully inserted. Check that the safety chains are secure. Verify the wiring harness is not dragging on the ground.
Inside the Wrangler, make sure the steering wheel is unlocked. The front wheels need to steer freely as you turn. If the steering wheel is locked, the tires will scrub and cause damage.
Required Equipment For Towing A Jeep Wrangler
You cannot tow a Wrangler with just any equipment. You need specific parts designed for the vehicle’s weight and towing method. Here is a checklist of essential items.
- Tow bar rated for at least 5,000 pounds
- Base plate kit for your Wrangler model year
- Safety chains with hooks
- Wiring harness with diode protection
- Supplemental braking system (required in most states)
- Towing mirrors for the motorhome
The supplemental braking system is often overlooked. Many states require a braking system for any vehicle over 3,000 pounds being towed. The Wrangler weighs around 4,000 pounds, so you need a brake controller.
Popular options include the Blue Ox Patriot and the ReadyBrute Elite. These systems apply the Wrangler’s brakes when the motorhome brakes. They prevent the towed vehicle from pushing the motorhome during stops.
Base Plate Installation Tips
Installing a base plate is a one-time job. You remove the front bumper or attach brackets to the frame. Most kits include detailed instructions for your specific model.
If you are not comfortable with mechanical work, hire a professional. A poorly installed base plate can fail at highway speeds. The cost of installation is worth the safety.
After installation, check the bolts periodically. Vibration can loosen them over time. Retorque them every 5,000 miles or before long trips.
Common Mistakes When Towing A Jeep Wrangler
Even experienced owners make errors. Here are the most frequent mistakes and how to avoid them.
Leaving The Transfer Case In 2H
This is the number one mistake. Towing with the transfer case in 2H locks the front and rear drivelines together. The transmission spins without lubrication, causing internal damage.
Always double-check the transfer case position before you drive away. Some owners install a reminder sticker on the dashboard.
Forgetting To Unlock The Steering Wheel
If the steering wheel is locked, the front wheels cannot turn. This forces the tires to slide during turns. It wears out the tires quickly and puts stress on the steering components.
Insert the key and turn it to the “On” or “Accessory” position. Do not start the engine. This unlocks the steering column.
Using The Wrong Wiring Harness
Jeep Wranglers have separate turn signal and brake light circuits. A standard 4-pin harness may not work correctly. You need a harness with diode protection to prevent feedback into the vehicle’s computer.
Check your owner’s manual for the correct wiring kit. Most aftermarket brands like Curt or Hopkins offer specific kits for Wranglers.
Not Checking Tire Pressure
Low tire pressure causes heat buildup during long tows. The tires can fail if they are underinflated. Inflate all four tires to the recommended pressure listed on the door jamb.
Also check the spare tire. If you get a flat, you need a usable spare.
Towing A Jeep Wrangler With Automatic Transmission
Automatic transmissions require extra care. The fluid pump only works when the engine is running. Towing with the engine off means the transmission is not lubricated.
However, the transfer case neutral position isolates the transmission. The output shaft spins, but the internal clutches and gears remain stationary. This is safe as long as the transfer case is in neutral.
Never tow an automatic Wrangler with the transfer case in Park. This locks the driveline and will destroy the transmission within miles.
If you have a JL Wrangler with the 8-speed automatic, the procedure is the same. Shift to Park, then move the transfer case to neutral. The transmission does not need to be in neutral.
Towing A Jeep Wrangler With Manual Transmission
Manual transmissions are simpler but still require the transfer case in neutral. You can leave the transmission in neutral or in gear. Some owners prefer to leave it in gear to prevent the input shaft from spinning.
If you leave it in gear, the clutch disc spins with the input shaft. This is fine for short distances but may cause wear over thousands of miles. For long tows, leave the transmission in neutral.
The clutch does not engage during towing, so there is no risk of damage. Just make sure the transfer case is in neutral and the parking brake is off.
Legal Requirements For Towing A Jeep Wrangler
Each state has different laws for towed vehicles. You need to check the regulations for every state you drive through. Here are the common requirements.
- Supplemental braking system for vehicles over 3,000 pounds
- Tow bar rated for the vehicle weight
- Safety chains with proper length and attachment
- Functional tail lights, brake lights, and turn signals
- Tow mirrors that show 200 feet behind the motorhome
Some states require a separate registration for the towed vehicle. Others exempt vehicles under a certain weight. Always verify before you travel.
The National Highway Traffic Safety Administration (NHTSA) also has guidelines. Follow their recommendations for safe towing practices.
Preparing Your Jeep Wrangler For Long Tows
If you plan to tow your Wrangler across the country, you need extra preparation. The vehicle will accumulate miles even though the engine is off. The suspension and tires bear the load.
Check the wheel bearings for play. Worn bearings can fail at highway speeds. Replace them if they feel loose.
Inspect the brake pads and rotors. The supplemental braking system uses the Wrangler’s brakes. Worn pads reduce stopping power.
Change the transfer case fluid if it is old. Fresh fluid ensures smooth shifting into and out of neutral. The fluid also lubricates the internal components during towing.
Lubricate the tow bar pivot points. Dry joints cause squeaking and wear. Use a lithium-based grease for best results.
Troubleshooting Common Towing Issues
Sometimes things go wrong. Here are solutions to common problems.
Transfer Case Won’t Shift Into Neutral
If the lever feels stuck, try rocking the vehicle slightly. The internal gears may be under tension. Shift the transmission between Drive and Reverse while gently pulling the transfer case lever.
For push-button transfer cases, make sure the transmission is in Park. The system will not allow neutral if the transmission is not in Park.
Tow Bar Won’t Latch
Check the alignment of the tow bar arms. They must be parallel to the ground. Adjust the height of the motorhome hitch if needed.
Clean the pins and receivers. Dirt and rust can prevent full engagement. Apply a light coat of grease to the pins.
Wiring Harness Not Working
Test the motorhome’s trailer plug first. Use a circuit tester to confirm power is present. If the motorhome plug works, check the Wrangler’s tail light fuses.
Some Wranglers have separate fuses for the trailer wiring. Consult the owner’s manual for the fuse location. Replace any blown fuses.
