This article answers the popular question: How do I replace the axles on my trailer?

The 8 steps outlined below are a simple single guide for replacing your trailer axles and springs. Oftentimes, when axles need replacing, the springs are also replaced. If you are only replacing your axle, and reusing your leaf springs, there will be an extra step where you will need to disconnect the springs from the axles and then reconnect the old springs to the new axles.

If you have questions while you are working through your axle and spring installation, give BlueSwift Axles a call and we’d be happy to assist you. As always, please refer to your installation guide for complete details on how to properly install your new axles and springs.

Step 1

Use a car jack to raise your trailer on jack stands. The jacks should be on the trailer’s frame and not on the axle. Ensure the jacks are steady and secured before crawling underneath the trailer. 

Step 2

Use a tire iron, impact, or socket to remove all of the tires on the trailer. 

Step 3

Disconnect the brakes by cutting two wires 

Step 4

Unbolt the leaf spring from the trailer using a racket, socket set, or impact.

Step 5

Once the spring is unbolted on both sides, the spring and axle will lower to the ground. Then slide the old axle out from under the trailer.

Step 6

Slide the new replacement axle and springs underneath the trailer. Using an assistant to help or a jack to hold the new axles and springs in place, re-bolt the leaf springs to the trailer on both sides. 

Step 7

Remove the jack that’s holding the axle up, and reconnect the brake lines by connecting the two wires.

Step 8

Reinstall the wheels and tires and then lower the jacks down so the trailer is back down on the ground.
