Essential Tips for Selecting the Perfect Replacement Leaf Spring for Your Trailer

Are you in need of a new leaf spring for your trailer? Replacing leaf springs can be a challenging task, but with the right tips and procedures, you can ensure a smooth and successful installation. In this article, we will provide you with essential tips for choosing the ideal replacement leaf spring for your trailer. So, let’s dive in!

Procedures for Replacing Leaf Springs

To begin the process of replacing your trailer’s leaf springs, you need to follow a set of procedures that will help you accomplish the task effectively. Here are the steps you should take:

Step 1: Make Preparations

Before you start extracting the old leaf springs, it’s important to prepare the stabilization system. This involves applying lubricant to the bolts, nuts, and brackets to loosen the suspension system. By doing this, you’ll ensure that the old leaves can be removed without causing any damage to the surrounding components.

Step 2: Elevate the Trailer and Gain Access to the Springs

To gain access to the rear leaf springs, you need to elevate the trailer and secure it in place. Start by setting chocks at the front tires to prevent the trailer from moving forward. Then, loosen the lug nuts on the rear wheels and elevate the trailer’s rear end using a hydraulic jack. Make sure to secure it with a jack brace under the rear axle.

Afterwards, remove the rear wheels while the trailer is suspended. This will give you direct exposure to both rear leaf springs, allowing you to proceed with the replacement.

Step 3: Take Away the Base Plate

In this step, you’ll learn how to detach the leaf springs. Begin by disconnecting the lower mounting stud, bolts, and shock absorbers. Then, remove the U-bolt nuts and the base plate. Next, raise the axle moderately and use a pry bar to remove the leaf spring load from the center pin.

Once the load is removed, detach the spring’s front and rear screws, as well as the outer plate. Release the shackle ring and shackle. These steps will prepare you for the proper installation of the new leaf springs.

Step 4: Install the Replacement Kit

With the old leaf springs removed, it’s time to install the replacement kit. Start by inserting the inner-shackle pivot pin through the shackle’s metal sleeve. Ensure that the new leaf spring is properly positioned. Keep in mind that the distance between the middle and the end may vary on each side.

Align the rear leaf spring precisely on the shackle and fasten it with latching nuts. It’s recommended to use new screws for a secure installation. This step will ensure that the replacement leaf springs are properly attached.

Step 5: Carry Out the Installation

Now that the new leaf spring is securely in place at the back, it’s time to complete the installation. Lift the front end of the leaf spring and position it between the front mounts. Secure the bolt with the securing nut, but avoid tightening it too firmly at this stage. The spring pack is not ready for final tightening yet.

Lower the back end of the leaf spring until it comes into contact with the spring and aligns at the center. Install the replacement U-bolts that came with your replacement kit. To ensure a secure fit, use a torque wrench to tighten the nuts and bolts. After approximately seven days, reevaluate the tightness to confirm a secure installation.

Remember, safety is crucial throughout the entire process. Make sure to reapply the shock springs with a torque wrench and follow the manufacturer’s recommendations for proper installation.

After completing the installation on one side, repeat the process on the opposite side. Once both sides are done, reinstall the rear wheels and tighten the lug nuts securely. Finally, remove the jack stand from underneath the trailer and lower the rear to the ground. Double-check the lug nuts to ensure they are securely fastened.

Choosing the right replacement leaf spring for your trailer is essential for maintaining its stability and performance.
