For anyone who frequently tows a trailer, whether for recreational purposes or work-related tasks, a square tube trailer jack is an essential component. They provide stability and ease of use when coupling and uncoupling a trailer. However, like any mechanical device, they can experience problems over time. Understanding these common problems and their solutions can help you keep your trailer jack in top condition.

1. Jack will not raise or lower

One of the most common problems with square tube trailer jacks is that they can get stuck and fail to raise or lower. This can be caused by a lack of lubrication, rust, or debris clogging the mechanism.

Solution:
Start by inspecting the jack for any visible debris or rust. Clean the area thoroughly and apply appropriate lubricant to moving parts. If the jack still isn't working, it may need to be disassembled for a more thorough cleaning or to replace worn parts.

2. Jack is wobbly or unsteady

A swinging trailer jack can create a major safety hazard. This instability is usually caused by loose bolts, worn bearings or bent square tubes.

Solution:
Check all bolts and fasteners to make sure they are tight. If it is found to be loose, please tighten it appropriately. For worn bearings, consider replacing them. If the square tube is bent, it may need to be straightened or replaced entirely to restore stability.

3. Jack is difficult to activate

Over time, the crank mechanism of a square tube trailer jack can become stiff, making it difficult to operate. This can be caused by rust, lack of lubrication, or internal wear.

Solution:
First, apply penetrating oil to the crank mechanism and let it soak in. Then, turn the crank back and forth to distribute the oil. If the problem persists, check the internal gears for wear and replace if necessary.

4. Jack cannot maintain weight

If your square tube trailer jack cannot handle the weight of your trailer, it could result in a dangerous situation. This problem may be caused by a faulty locking mechanism or worn hydraulic components.

Solution:
Check the locking mechanism to make sure it is properly engaged. If it doesn't work, it may need to be adjusted or replaced. For hydraulic jacks, check for leaks or signs of wear. If the hydraulic fluid is low, refill it, but if the jack continues to fail, consider replacing the hydraulic cylinder.

5. Corrosion and Rust

Corrosion is a common problem with trailer jacks, especially if they are regularly exposed to moisture or road salt. Rust can weaken the structure and functionality of your jack.

Solution:
Check your trailer jack regularly for signs of rust. If found, sand the affected area and apply rust-resistant primer and paint. Also, consider using a protective cover when the jack is not in use to minimize contact with components.

In summary

Square tube trailer jacks​ are essential for safe and efficient towing, but they can experience various problems over time. By understanding these common problems and their solutions, you can ensure that your trailer jack remains in good working order. Regular maintenance, including cleaning, lubrication, and inspections, will go a long way in extending the life of your trailer jack and enhancing your towing experience. Remember, a well-maintained jack not only improves functionality but also ensures safety on the road.
