Towing a 4×4 Jeep on a dolly requires specific steps to protect the transfer case. Many people assume you can just hook up and go, but that can damage your Jeep’s drivetrain. This guide explains exactly how to tow a 4×4 Jeep on a dolly safely, step by step.
Before you start, know your Jeep model. Different transfer cases have different towing requirements. Always check your owner’s manual first.
Why Towing A 4X4 Jeep On A Dolly Is Different
Four-wheel-drive Jeeps have a transfer case that connects the front and rear axles. If you tow with the wrong wheels on the ground, you can destroy the transfer case. Dollies lift only the front wheels, so the rear wheels spin. That can cause serious damage unless you follow the right procedure.
Some Jeeps can be towed on a dolly with the transfer case in neutral. Others require a driveshaft disconnect or a flatbed. This article covers the most common methods.
Check Your Jeep’s Transfer Case Type
Jeep uses several transfer cases. The most common are the NP231, NP242, and the Rock-Trac. Each has different neutral positions. Some have a “Neutral” position that disconnects both axles. Others only disconnect the rear. You must know which one you have.
- NP231: Found in many Wranglers. Has a neutral position for towing.
- NP242: Found in some Grand Cherokees. Also has a neutral position.
- Rock-Trac: Found in Rubicon models. Same as NP231 but stronger.
If your transfer case does not have a true neutral, you cannot tow on a dolly without modifications. You might need to remove the rear driveshaft.
How To Tow A 4X4 Jeep On A Dolly
Here is the step-by-step process for towing your 4×4 Jeep on a dolly. Follow each step carefully to avoid damage.
Step 1: Prepare The Dolly
Make sure your dolly is rated for your Jeep’s weight. A Jeep Wrangler weighs around 4,000 pounds. A Grand Cherokee can be 5,000 pounds. Check the dolly’s capacity. Also check tire straps, chains, and safety cables for wear.
Position the dolly on level ground. Chock the rear wheels of the dolly so it doesn’t roll. Lower the dolly’s ramp if it has one.
Step 2: Set The Transfer Case To Neutral
This is the most critical step. With the engine running, shift the transmission to neutral. Then shift the transfer case to neutral. You’ll feel a detent. Some transfer cases require you to shift through 4L first. Check your manual.
After shifting, turn off the engine. Leave the transmission in neutral. The transfer case must stay in neutral. If you turn the engine off with the transfer case in gear, the rear wheels will lock up when you tow.
Double-check that the transfer case is in neutral. You can test this by trying to roll the Jeep forward. If it rolls freely, you are good.
Step 3: Load The Jeep Onto The Dolly
Drive the Jeep up the ramp onto the dolly. Center the front wheels in the wheel trays. Make sure the tires are fully seated. Then apply the parking brake. Put the transmission in park (or first gear if manual).
Now release the parking brake. This is important because the parking brake locks the rear wheels. If you leave it on, the rear wheels won’t spin freely.
Step 4: Secure The Front Wheels
Use the dolly’s straps to secure the front wheels. Tighten them evenly. Make sure the straps are not twisted. Check that the wheels cannot move side to side. Most dollies have ratchet straps. Do not overtighten, but make them snug.
Attach safety chains from the dolly to the Jeep’s frame. Cross them under the dolly tongue for better stability. Also attach the dolly’s electrical connector for taillights.
Step 5: Verify The Rear Wheels Are Free
Before you drive away, confirm the rear wheels can spin. Jack up the rear of the Jeep slightly and spin a wheel by hand. It should turn freely. If it does not, the transfer case might still be engaged. Recheck step 2.
If the rear wheels are locked, do not tow. You will damage the transfer case. Remove the rear driveshaft if needed.
Common Mistakes When Towing A 4X4 Jeep On A Dolly
Many people make errors that lead to costly repairs. Here are the most common mistakes and how to avoid them.
Mistake 1: Leaving The Transfer Case In 2H Or 4H
If you tow with the transfer case in 2H, the rear wheels are connected to the transmission. The transmission will spin without lubrication, causing damage. Always shift to neutral.
Mistake 2: Forgetting To Release The Parking Brake
The parking brake locks the rear wheels. If you leave it on, the rear wheels cannot spin. This puts stress on the drivetrain. Always release it after loading.
Mistake 3: Towing With The Transmission In Park
If the transfer case is in neutral but the transmission is in park, the rear wheels are still locked. The transmission park pawl engages the output shaft. Shift the transmission to neutral before towing.
Mistake 4: Not Checking The Owner’s Manual
Every Jeep model is different. Some newer Jeeps have electronic shift transfer cases that require a specific procedure. Always read the manual. If you lost it, check online forums or Jeep’s website.
When You Cannot Tow On A Dolly
Some Jeeps cannot be towed on a dolly at all. These include:
- Jeeps with full-time four-wheel drive that lacks a neutral position.
- Jeeps with automatic transmissions that require the rear wheels to be off the ground.
- Jeeps with modified suspension that makes loading difficult.
In these cases, use a flatbed trailer or tow the Jeep with all four wheels off the ground. A dolly is not safe for these vehicles.
How To Remove The Rear Driveshaft
If your Jeep requires it, removing the rear driveshaft is an option. This disconnects the rear axle from the transfer case. Here is how:
- Jack up the rear of the Jeep and support it on jack stands.
- Mark the driveshaft and differential yoke with paint for alignment.
- Remove the bolts at the differential end using a socket wrench.
- Slide the driveshaft out of the transfer case. Some fluid may leak.
- Secure the driveshaft with a bungee cord or tape it to the undercarriage.
- Lower the Jeep. The rear wheels will now spin freely.
Reinstall the driveshaft after towing. Torque the bolts to spec.
Safety Tips For Towing A 4X4 Jeep On A Dolly
Towing changes how your vehicle handles. Follow these safety tips.
- Check tire pressure on both the dolly and the Jeep’s rear tires. Low pressure can cause wobble.
- Drive slower than normal. Towing reduces braking and stability.
- Avoid sharp turns. The dolly can jackknife.
- Use a weight distribution hitch if the dolly tongue weight is high.
- Check straps and chains every time you stop.
What To Do If The Jeep Starts To Shimmy
Sometimes the rear of the Jeep will wobble at highway speeds. This is called “death wobble” on Jeeps. It can happen when towing if the rear wheels are out of balance. Slow down immediately. Check tire balance and alignment. If it persists, stop and inspect the dolly straps.
Frequently Asked Questions
Can I Tow A 4X4 Jeep On A Dolly With An Automatic Transmission?
Yes, but you must put the transfer case in neutral. The transmission can stay in park or neutral. Some automatic transmissions require the engine to be running when shifting the transfer case. Check your manual.
Do I Need To Disconnect The Battery When Towing A Jeep On A Dolly?
No, you do not need to disconnect the battery. However, make sure the steering wheel is unlocked. Some Jeeps have a steering lock that engages when the key is removed. Leave the key in the ignition or use a steering wheel lock bypass.
How Fast Can I Tow A Jeep On A Dolly?
Most manufacturers recommend not exceeding 55 mph. Towing at higher speeds can overheat the rear axle bearings. Also, the dolly tires are not rated for high speeds. Stay under 55 mph for safety.
Can I Tow A Lifted Jeep On A Dolly?
It depends on the lift height. A moderate lift (2-3 inches) is usually fine. Higher lifts may cause the front bumper to hit the dolly’s wheel trays. Measure clearance before loading. You might need a dolly with adjustable trays.
What Happens If I Tow With The Transfer Case In 4H?
You will damage the transfer case. The front and rear axles will fight each other, causing binding. This can strip gears or break the chain inside the transfer case. Always use neutral.
Final Checks Before Hitting The Road
Before you drive away, do a final walkaround. Check that the dolly is securely attached to your tow vehicle. Verify the safety chains are crossed and not dragging. Test the taillights and turn signals. Make sure the Jeep’s steering wheel is unlocked and the tires are not rubbing on the dolly.
If you are towing a long distance, plan stops every 100 miles to inspect everything. Feel the dolly wheel hubs for heat. If they are hot, the bearings might be failing. Also check the Jeep’s rear tires for wear.
Towing a 4×4 Jeep on a dolly is not difficult, but it requires attention to detail. Follow these steps and you will arrive safely without damage. If you are unsure, consult a professional or use a flatbed trailer. Your Jeep will thank you.
Remember, the key is the transfer case neutral position. Get that right and the rest is straightforward. Happy towing.
