Jacking up an RV trailer is essential for tire changes, bearing maintenance, and winterization, but doing it wrong can lead to serious injury or damage. This guide provides a step-by-step approach to safely and effectively lifting your RV trailer.
Understanding the Why and When
Before diving into the ‘how,’ let’s address the crucial question: Why jack up an RV trailer in the first place? Typically, you’ll need to lift your trailer for one of three main reasons: performing routine maintenance such as tire replacement or wheel bearing service, leveling the trailer for comfortable camping, or preparing it for long-term storage, including taking the weight off the tires. Knowing the specific reason helps determine the best method and safety precautions to take. Improper jacking can lead to trailer frame damage, personal injury, or even the RV toppling over, so meticulous planning is key.
Essential Equipment and Safety Precautions
Gathering Your Tools
Safety is paramount. Before even thinking about lifting your trailer, ensure you have the right tools. This includes:
- A suitable jack: This could be a bottle jack, scissor jack, or hydraulic jack. The jack must have a weight capacity exceeding the weight of the trailer at the jacking point.
- Jack stands: Absolutely essential! Never work under an RV supported only by a jack. Jack stands provide crucial secondary support. Ensure they are rated for the weight.
- Wheel chocks: Prevent the trailer from rolling while you are working. Place them firmly behind and in front of the tires on the opposite side of the trailer you’re lifting.
- Gloves: Protect your hands.
- Safety glasses: Protect your eyes from debris.
- Wood blocks or jack pads: To distribute the weight of the jack and jack stands, especially on soft ground.
- Owner’s manual: Consult your RV’s owner’s manual for specific jacking points and recommendations.
- Torque wrench: For properly tightening lug nuts after reinstalling the tires.
Prioritizing Safety
- Choose a level surface: This is critical. A slight incline can make the trailer unstable.
- Chock the wheels: As mentioned above, ensure the wheels on the opposite side of the trailer are securely chocked.
- Engage the emergency brake: Double-check that the emergency brake is firmly engaged.
- Never work alone: Having someone nearby in case of an emergency is always a good idea.
- Wear appropriate safety gear: Gloves and safety glasses are essential.
- Inspect the jack and jack stands: Ensure they are in good working order and free from damage.
- Never exceed the weight capacity: Overloading the jack or jack stands can lead to catastrophic failure.
- Keep children and pets away: The area around the trailer should be clear of any obstructions or hazards.
Step-by-Step Guide to Jacking Up Your RV Trailer
Preparation
- Choose your jacking point: Consult your RV’s owner’s manual for designated jacking points. These are typically located near the axles on the trailer frame.
- Position the jack: Place a wood block or jack pad under the jack if you are working on soft ground. Position the jack under the designated jacking point.
- Raise the jack: Slowly raise the jack until it makes contact with the jacking point.
Lifting and Securing
- Lift the trailer: Continue raising the jack, carefully monitoring the trailer for any signs of instability. Lift only enough to remove the tire or perform the necessary maintenance.
- Position the jack stands: Place jack stands under the trailer frame, near the jacking point. Ensure they are securely positioned and at the appropriate height.
- Lower the trailer onto the jack stands: Slowly lower the jack until the trailer’s weight is fully supported by the jack stands.
- Double-check stability: Give the trailer a gentle nudge to ensure it is stable and secure on the jack stands. Never work under the trailer until you are confident that it is properly supported.
Lowering and Finishing
- Raise the trailer slightly with the jack: Enough to remove the jack stands.
- Remove the jack stands: Carefully remove the jack stands from under the trailer.
- Slowly lower the trailer: Gradually lower the jack until the tire is back on the ground.
- Remove the jack: Remove the jack from under the trailer.
- Torque the lug nuts: Using a torque wrench, tighten the lug nuts to the manufacturer’s specifications. This is crucial for ensuring the wheel is securely attached.
- Remove the wheel chocks: Only after the tire is securely back on the ground.
- Test drive (if applicable): If you have replaced a tire, take the trailer for a short test drive to ensure everything is working properly.
Frequently Asked Questions (FAQs)
FAQ 1: Where are the correct jacking points on my RV trailer?
Consult your RV’s owner’s manual! This is the definitive source for identifying the designated jacking points, which are typically located on the trailer frame near the axles. Using incorrect jacking points can damage the frame.
FAQ 2: What type of jack is best for an RV trailer?
The best type depends on the trailer’s weight and your personal preference. Bottle jacks are compact and powerful but have a limited range. Scissor jacks are more stable but require more effort to operate. Hydraulic jacks offer the best of both worlds, providing power and stability. Choose a jack with a weight capacity exceeding the trailer’s weight at the jacking point.
FAQ 3: How high should I jack up my RV trailer?
Only jack the trailer high enough to remove the tire or perform the necessary maintenance. Unnecessary lifting increases the risk of instability. A few inches is usually sufficient.
FAQ 4: Can I use the stabilizing jacks to lift my RV trailer?
No! Stabilizing jacks are designed to prevent rocking and swaying, not to lift the trailer. Using them for lifting can damage the jacks and the trailer frame.
FAQ 5: What if the ground is uneven?
Find a more level spot. If that’s impossible, use large, sturdy wood blocks under the jack and jack stands to create a level surface. The larger the blocks, the more stable the base.
FAQ 6: How often should I check the tire pressure after changing a tire?
Check the tire pressure before each trip and regularly during the trip, especially after changing a tire. Proper tire pressure is crucial for safety and fuel efficiency.
FAQ 7: How do I know if my jack stands are strong enough?
Jack stands have a weight capacity rating. Make sure the rating of each jack stand is equal to or greater than half the weight of your trailer (since you’ll be using at least two). Never exceed the rated capacity.
FAQ 8: What do I do if the trailer starts to slip off the jack?
Immediately stop working and lower the trailer. Reassess the situation, reposition the jack, and ensure the jack stands are securely in place. Prioritize safety above all else.
FAQ 9: Can I use a car jack to lift my RV trailer?
Potentially, but exercise extreme caution. Only if the car jack has sufficient weight capacity and lifting range. RV trailers are heavier than most cars, so using an undersized jack is dangerous. A dedicated RV jack is always recommended.
FAQ 10: How often should I inspect my tires?
Inspect your tires before each trip and periodically during longer trips. Look for signs of wear, damage, or improper inflation.
FAQ 11: What is the correct torque for tightening lug nuts?
The correct torque specification is usually found in your RV’s owner’s manual or on the wheel itself. Using the wrong torque can lead to loose lug nuts or damaged wheel studs. Use a torque wrench to ensure accurate tightening.
FAQ 12: Should I deflate the tires before jacking up the trailer for tire removal?
Deflating the tires a little can make them easier to remove from the hub, especially if they are stuck. However, it is not strictly necessary and can be skipped if you prefer. Just be prepared for a little more effort when removing the tire.
