Installing a trailer jack stand is crucial for ensuring the safety and stability of your trailer during maintenance, storage, or when unhitched. This comprehensive guide provides detailed instructions and answers frequently asked questions to help you complete the task safely and effectively.
Understanding the Importance of Trailer Jack Stands
Trailer jack stands are far more than just optional accessories. They are essential safety devices designed to support the weight of a trailer when it’s not connected to a tow vehicle. This is particularly important during activities like tire changes, bearing maintenance, or even simply storing the trailer for extended periods. Without proper support, the trailer’s weight could strain the tongue jack, causing it to fail or, even worse, leading to a catastrophic collapse, potentially resulting in serious injury or property damage.
Using jack stands helps distribute the load evenly, preventing excessive stress on any single component of the trailer’s frame. They offer a robust and reliable support system, allowing you to work on or around the trailer with confidence. Moreover, consistent use can prolong the life of your trailer by preventing warping or other damage caused by uneven weight distribution.
Preparing for Installation
Before you even think about lifting your trailer, proper preparation is key. This stage involves gathering the right tools, assessing the work area, and understanding the safety precautions.
Gathering Necessary Tools and Materials
- Trailer Jack Stands: Select the correct weight capacity jack stands appropriate for your trailer’s Gross Vehicle Weight Rating (GVWR). Always err on the side of caution and choose stands that exceed the GVWR.
- Wheel Chocks: Absolutely essential for preventing the trailer from rolling.
- Gloves: To protect your hands.
- Safety Glasses: To protect your eyes from debris.
- Wrench: For adjusting the jack stands if they have screw-type adjustment mechanisms.
- Level (Optional): To ensure the trailer is level once supported.
- Wood Blocks (Optional): To provide a larger, more stable base for the jack stands on soft surfaces.
- Tongue Jack: To raise the trailer initially.
Selecting a Safe Work Area
Choose a flat, level, and solid surface to work on. Avoid soft ground like grass or gravel unless you use wood blocks to distribute the load. Ensure there’s ample space around the trailer to move freely and work safely.
Emphasizing Safety Precautions
- Never work under a trailer supported only by a tongue jack. Always use jack stands.
- Always use wheel chocks. Even on level ground, the trailer can shift.
- Read and understand the instructions that came with your jack stands.
- Wear safety glasses and gloves.
- If you are unsure about any step, consult a professional.
Step-by-Step Installation Guide
Now that you’re prepared, let’s get to the actual installation process. Follow these steps carefully:
Step 1: Chock the Wheels
This is the most crucial safety step. Place wheel chocks securely behind and in front of the tires on both sides of the trailer. Ensure the chocks are firmly in place and will prevent any movement.
Step 2: Raise the Trailer with the Tongue Jack
Use the trailer’s tongue jack to raise the trailer frame to the desired height. Raise it high enough to allow for the jack stands to be positioned underneath the frame. Avoid raising the trailer excessively high, as this can compromise stability.
Step 3: Position the Trailer Jack Stands
Locate the strongest points on the trailer frame for positioning the jack stands. These are typically near the axles or at designated frame support points (consult your trailer’s manual). Avoid placing the stands on thin metal, wiring, or plumbing. Position the stands perpendicular to the frame.
Step 4: Adjust the Jack Stand Height
Adjust the height of the jack stands so that they make firm contact with the trailer frame. Most jack stands have adjustable screw mechanisms or pin-locking systems. Ensure the stands are properly engaged and locked into position according to the manufacturer’s instructions.
Step 5: Lower the Trailer onto the Jack Stands
Carefully lower the trailer using the tongue jack until the weight is fully supported by the jack stands. Monitor the stands to ensure they are stable and not shifting. You should feel the weight transfer from the tongue jack to the stands.
Step 6: Verify Stability
Once the trailer is fully supported, give it a gentle shake to test its stability. If there is any wobble or instability, re-adjust the jack stands or reposition them slightly. A level can be used to ensure the trailer is sitting as level as possible.
Step 7: Lower the Tongue Jack (Optional)
After confirming stability, you can slightly lower the tongue jack so that it no longer bears any weight. This removes any potential for the tongue jack to fail and further isolates the trailer’s support to the jack stands.
Removing Trailer Jack Stands
Removing the jack stands is essentially the reverse of the installation process.
Step 1: Raise the Trailer with the Tongue Jack
Raise the trailer slightly with the tongue jack, enough to remove the weight from the jack stands.
Step 2: Remove the Jack Stands
Carefully remove the jack stands.
Step 3: Lower the Trailer
Slowly lower the trailer using the tongue jack until the tires are firmly on the ground.
Step 4: Remove the Wheel Chocks
Once the trailer is safely on the ground, remove the wheel chocks.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about trailer jack stands:
-
What size jack stand do I need for my trailer?
- You need jack stands rated for at least your trailer’s GVWR (Gross Vehicle Weight Rating). Look for this rating on your trailer’s VIN plate. Divide the GVWR by two to determine the minimum weight capacity needed for each jack stand. It’s always best to choose stands with a higher capacity for added safety.
-
Where should I place the jack stands on my trailer frame?
- Place the stands at designated frame support points, usually near the axles. Consult your trailer’s manual for specific recommendations. If the manual is unavailable, look for reinforced areas of the frame or consult a professional.
-
Can I use wood blocks under the jack stands?
- Yes, using wood blocks can provide a larger, more stable base, especially on soft surfaces like grass or gravel. Ensure the wood is sturdy and can support the weight of the trailer.
-
How often should I inspect my trailer jack stands?
- Inspect your jack stands before each use for any signs of damage, rust, or wear. Replace them if they are damaged.
-
Is it safe to work under a trailer supported by jack stands?
- Yes, if the jack stands are properly rated, installed correctly, and in good condition. However, always exercise extreme caution and never place yourself in a position where a jack stand failure could cause serious injury.
-
What type of jack stand is best for my trailer?
- The best type depends on your trailer’s size, weight, and frame design. Common types include screw-type, pin-type, and ratchet-type. Ensure the jack stand has a sturdy base and a reliable locking mechanism.
-
Can I use a car jack instead of trailer jack stands?
- While a car jack can be used to lift the trailer, it should never be used as the sole means of support. Car jacks are designed for temporary use and are not as stable as dedicated trailer jack stands. Always use jack stands after lifting the trailer with a jack.
-
What if the ground is uneven?
- If the ground is slightly uneven, use shims or wood blocks to level the jack stands. If the ground is significantly uneven, choose a different location.
-
Are there any alternatives to jack stands?
- While some specialized trailer support devices exist, jack stands are the most common and reliable solution for most trailers. Alternative methods, like using concrete blocks, are not recommended due to their instability.
-
How do I maintain my trailer jack stands?
- Keep your jack stands clean and lubricated. Regularly inspect them for rust or damage. Store them in a dry place when not in use.
