Installing trailer stabilizer jacks is a straightforward process that significantly enhances the stability of your recreational vehicle, providing a more comfortable and secure experience while camping. These jacks prevent excessive rocking and swaying, transforming your trailer from a shaky box into a solid home away from home.
Understanding Trailer Stabilizer Jacks
Trailer stabilizer jacks aren’t designed to lift your trailer or level it; their primary function is to minimize movement once the trailer is already relatively level. Understanding this distinction is crucial to using them correctly and avoiding damage to your trailer’s frame. Choosing the right type of jack for your trailer’s size and weight is also important.
Types of Trailer Stabilizer Jacks
Several types of stabilizer jacks are available, each with its own strengths and weaknesses.
- Scissor Jacks: These are the most common type, offering a good balance between cost, ease of use, and weight capacity. They operate with a screw mechanism that allows you to extend or retract the jack.
- Tongue Jacks: Located at the front of the trailer, tongue jacks primarily assist in coupling and uncoupling from the tow vehicle, but many models also include a stabilizing function.
- Corner Jacks: These jacks are permanently mounted to the trailer frame at each corner and are usually deployed by a lever or hand crank.
- Electric Stabilizer Jacks: These are convenient for those who want to avoid manual cranking. They are powered by the trailer’s electrical system and can be raised and lowered with the push of a button.
Safety First: Before You Begin
Before attempting to install or use trailer stabilizer jacks, prioritize safety. Always wear appropriate safety gear, including gloves and eye protection. Ensure the trailer is parked on a relatively level surface and that the wheels are securely chocked to prevent rolling. Finally, read and understand the manufacturer’s instructions for your specific jacks.
Installing Your Trailer Stabilizer Jacks: Step-by-Step
The installation process varies slightly depending on the type of jack and your trailer’s construction, but the following steps provide a general guideline:
- Preparation: Gather all necessary tools and materials, including the jacks, mounting hardware (bolts, nuts, washers), a drill, drill bits (appropriate for the metal or wood of your trailer frame), a wrench set, a level, and safety gear. Carefully review the jack manufacturer’s instructions.
- Locating Mounting Points: Identify suitable mounting points on the trailer frame. These points should be solid, structurally sound areas capable of supporting the weight of the trailer. Consult your trailer’s manual for recommended mounting locations. Avoid mounting jacks to thin sheet metal or areas that show signs of rust or damage.
- Marking and Drilling: Use the jack’s mounting plate as a template to mark the locations for the mounting holes on the trailer frame. Ensure the jack is positioned correctly and that it will have adequate clearance when extended. Use a drill with the appropriate size drill bit to create the mounting holes.
- Mounting the Jacks: Attach the jacks to the trailer frame using the provided mounting hardware. Ensure the bolts are tightened securely, but avoid over-tightening, which could damage the frame or the jacks. Use washers to distribute the load evenly.
- Testing and Adjusting: After installation, test the jacks by extending and retracting them. Check for smooth operation and ensure they are properly aligned. Use a level to verify that the trailer is stable and relatively level. Make any necessary adjustments to ensure proper functionality.
- Applying Lubricant: Applying a quality lubricant to the screw mechanism of the jacks will ensure smoother operation and extend their lifespan. Use a lubricant specifically designed for metal-on-metal contact.
Essential Tips for Using Stabilizer Jacks
Once installed, use these jacks correctly for optimal performance and safety.
- Never Use Stabilizer Jacks to Lift the Trailer: These jacks are designed to stabilize, not lift. Attempting to lift the trailer with them can damage the jacks and the trailer frame.
- Use Blocking Under the Jacks: On soft ground, place wooden blocks or jack pads under the jacks to prevent them from sinking.
- Level the Trailer First: Use leveling blocks under the wheels before deploying the stabilizer jacks. This reduces the strain on the jacks and ensures they function properly.
- Extend the Jacks Evenly: Extend all the jacks to roughly the same height to distribute the weight evenly.
- Check for Stability Regularly: After settling, re-tighten the jacks if necessary to maintain stability.
FAQs about Trailer Stabilizer Jacks
These frequently asked questions address common concerns and provide further clarification on the use and installation of trailer stabilizer jacks.
1. Can I use stabilizer jacks to level my trailer?
No. Stabilizer jacks are not designed to level your trailer. Their primary function is to minimize rocking and swaying after the trailer has been leveled using other methods, such as leveling blocks placed under the wheels. Attempting to level with stabilizer jacks can damage both the jacks and the trailer frame.
2. What type of stabilizer jacks are best for my trailer?
The best type depends on your trailer’s size, weight, and your budget. Scissor jacks are a popular and versatile option for many trailers. Consider electric jacks for added convenience. Research weight capacities and reviews before making a purchase.
3. How many stabilizer jacks do I need?
Typically, you will need four stabilizer jacks, one for each corner of the trailer. This provides balanced support and minimizes movement effectively.
4. Where should I mount the stabilizer jacks on my trailer?
Mount the jacks on the trailer frame, ideally near the corners. Consult your trailer’s manual for recommended mounting locations. Ensure the mounting points are solid and structurally sound.
5. What tools do I need to install stabilizer jacks?
You’ll typically need a drill, drill bits, a wrench set, a socket set, measuring tape, safety glasses, gloves, and the appropriate mounting hardware (bolts, nuts, washers).
6. What size drill bit should I use for the mounting holes?
Use a drill bit size that matches the diameter of the mounting bolts. Refer to the jack manufacturer’s instructions for the specific size required.
7. How tight should I tighten the mounting bolts?
Tighten the bolts securely, but avoid over-tightening, which can damage the frame or the jacks. Use a torque wrench if possible, and follow the manufacturer’s recommended torque specifications.
8. What can I do if the ground is too soft for the jacks?
Place wooden blocks or jack pads under the jacks to distribute the weight and prevent them from sinking into the soft ground.
9. How often should I lubricate my stabilizer jacks?
Lubricate your jacks periodically, especially after exposure to rain, dirt, or salt. Use a lubricant specifically designed for metal-on-metal contact.
10. What if my stabilizer jacks are difficult to crank?
Check for any obstructions or damage to the screw mechanism. Apply lubricant liberally. If the problem persists, consider replacing the jacks.
11. Can I extend my stabilizer jacks too far?
Yes. Extending the jacks too far can overstress them and potentially cause damage. Only extend them enough to stabilize the trailer.
12. What are the safety precautions I should take when using stabilizer jacks?
Always use wheel chocks. Never use the jacks to lift the trailer. Wear safety glasses and gloves during installation. Regularly inspect the jacks for damage.
