Safely and effectively jacking up your travel trailer is essential for maintenance, tire changes, and winterization. Understanding the correct procedures and equipment protects you, your trailer, and prevents costly damage.
Why and When You Need to Jack Up Your Travel Trailer
Jacking up your travel trailer isn’t something you’ll do daily, but knowing the proper technique is crucial for several common situations:
- Changing a flat tire: This is the most frequent reason and requires a safe and stable lifting method.
- Servicing the axles or brakes: Gaining access for repairs or maintenance necessitates lifting the trailer’s wheels.
- Winterizing: Sometimes, lifting one side slightly aids in draining water lines completely.
- Leveling on uneven ground: While leveling blocks are the preferred solution, sometimes a jack is needed for more significant discrepancies.
Ignoring proper procedures can lead to serious accidents and damage. Therefore, this guide will walk you through the necessary steps to safely and effectively jack up your travel trailer.
Essential Tools and Equipment
Before you even think about lifting your trailer, gather the right tools. This isn’t a task to be taken lightly, and having the correct equipment makes all the difference between a smooth operation and a potential disaster.
- Proper Jack: This is the heart of the operation. Scissor jacks and bottle jacks are common, but always consult your trailer’s manual for recommended weight capacity. Never exceed the jack’s rated capacity. Consider investing in a heavy-duty hydraulic bottle jack for added safety and ease of use.
- Jack Stands: These are non-negotiable. Jack stands are critical safety devices that support the trailer once lifted. Never work under a trailer supported only by a jack. Choose jack stands rated for the weight of your trailer.
- Wheel Chocks: These prevent the trailer from rolling, providing an extra layer of safety. Place them securely behind and in front of the tires on the opposite side of where you’re jacking.
- Lug Wrench: For removing and tightening lug nuts. Ensure it’s the correct size for your trailer’s wheel studs.
- Torque Wrench: Crucial for tightening lug nuts to the manufacturer’s specified torque. Overtightening or undertightening can lead to serious problems.
- Gloves: Protect your hands from dirt and grime.
- Protective Eyewear: Safety first! Protect your eyes from flying debris.
- Level: Helps ensure the trailer is level after lifting.
- Wooden Blocks: Useful for leveling the jack on soft or uneven ground. They can also provide extra height.
- Owner’s Manual: This is your bible. Consult it for specific instructions and weight ratings for your trailer.
Step-by-Step Guide to Safely Jacking Up Your Travel Trailer
This procedure assumes you’re changing a tire, but the principles apply to other situations as well.
- Choose a Safe Location: Park on a level, solid surface away from traffic. Engage the parking brake on your tow vehicle.
- Chock the Wheels: Place wheel chocks firmly against the tires on the opposite side of the trailer from the tire you’re changing.
- Locate the Jacking Point: Consult your owner’s manual. Typically, jacking points are located on the frame near the axles. Never jack directly on the axle itself, as this can damage it. Look for reinforced plates or marked areas.
- Position the Jack: Place the jack under the designated jacking point. If the ground is soft, use a wooden block under the jack for stability. Ensure the jack is positioned securely and squarely against the frame.
- Raise the Trailer: Slowly and steadily raise the trailer using the jack. Monitor the stability of the jack and the trailer throughout the process. Lift the trailer only high enough to remove the flat tire and install the spare.
- Position the Jack Stands: This is the most crucial safety step. Immediately place jack stands under the frame near the jacking point. Ensure they are properly positioned and securely engaged. Lower the trailer onto the jack stands, allowing them to bear the weight.
- Remove the Wheel: Using the lug wrench, loosen the lug nuts on the flat tire. Once they are loose, fully remove them and take off the wheel.
- Install the Spare Tire: Mount the spare tire onto the wheel studs. Hand-tighten the lug nuts in a star pattern.
- Lower the Trailer: Slowly raise the trailer slightly with the jack to remove the jack stands. Carefully lower the trailer until the tire is on the ground, but the full weight of the trailer isn’t yet on it.
- Tighten the Lug Nuts: Using the torque wrench, tighten the lug nuts to the manufacturer’s specified torque in a star pattern. This is critical for preventing wheel separation.
- Lower the Trailer Completely: Slowly lower the trailer until the tire is fully supporting the weight.
- Final Check: Remove the wheel chocks and double-check that the lug nuts are properly torqued. Retorque them after driving a short distance (e.g., 50 miles).
Important Safety Considerations
- Never work under a trailer supported only by a jack. This is a fundamental safety rule.
- Always use jack stands. They are your primary protection against a collapsed jack.
- Consult your owner’s manual for specific jacking points and weight ratings.
- Inspect your jacks and jack stands regularly for damage.
- Be aware of the terrain and use appropriate blocks for stability.
- If unsure, consult a professional mechanic or RV technician.
Frequently Asked Questions (FAQs)
1. What type of jack is best for a travel trailer?
There isn’t a single “best” jack, but hydraulic bottle jacks are often preferred for their lifting power and ease of use. Scissor jacks are common but may require more cranking. Always ensure the jack’s weight capacity exceeds your trailer’s weight.
2. Where exactly should I place the jack stands?
Place the jack stands under the frame rails, as close as possible to the jacking point. Avoid placing them on thin metal sheeting or other unsupported areas.
3. Can I use a car jack on my travel trailer?
While technically possible if the car jack has sufficient weight capacity, it’s not recommended. Car jacks are often designed for different lifting heights and stability requirements. A dedicated trailer jack is safer and more reliable.
4. How do I determine the correct torque for my lug nuts?
The correct torque specification is usually found in your owner’s manual. If not, consult a reputable tire shop or RV service center.
5. What should I do if the ground is uneven?
Use wooden blocks under the jack to create a stable, level base. If the unevenness is extreme, reconsider jacking up the trailer in that location.
6. My trailer doesn’t have designated jacking points. Where should I lift it?
If your trailer lacks designated jacking points, consult your owner’s manual or contact the manufacturer directly for guidance. Lifting in the wrong place can cause serious structural damage.
7. How often should I inspect my jacks and jack stands?
Inspect your jacks and jack stands before each use for signs of damage, such as rust, cracks, or bent components. Replace damaged equipment immediately.
8. What if my jack isn’t lifting high enough?
Use a sturdy wooden block between the jack and the jacking point to gain additional height. Ensure the block is wide enough to provide a stable base.
9. Can I use the stabilizer jacks to lift the trailer for tire changes?
No. Stabilizer jacks are designed to stabilize the trailer, not to lift it. Using them for lifting can damage the jacks and the trailer frame.
10. What if I’m unable to remove a lug nut?
Use a penetrating oil like WD-40 or PB Blaster and let it soak for a few minutes. If that doesn’t work, consider using a breaker bar for extra leverage. If all else fails, consult a professional.
11. How do I prevent the jack from sinking into soft ground?
Use a large, solid wooden block or a steel plate under the jack to distribute the weight over a wider area.
12. What if I don’t have a torque wrench? Can I just tighten the lug nuts by hand?
While hand-tightening is better than nothing in an emergency, it’s strongly recommended to use a torque wrench and tighten the lug nuts to the manufacturer’s specified torque as soon as possible. Undertightening can cause the wheel to come loose, while overtightening can damage the wheel studs. Visit a tire shop or purchase a torque wrench.
By following these guidelines, you can safely and effectively jack up your travel trailer for maintenance and repairs. Remember that safety is paramount, and taking your time to do the job right is always the best approach.
