Having a boat is a luxury for many people, but if you have one, it's often more affordable to tow your boat back and forth to the lake as opposed to paying for a slip. If you get into an accident and damage the axle, or it breaks under the weight of the boat you're towing, you'll need to replace the axle assembly. This is a fairly large task, and should take a few hours to do correctly.
Things You'll Need
- Jack stands
- Tire iron
- 1/2-inch ratchet and socket set
- Replacement axle
Lift the trailer using the jack, and place it on jack stands. Make sure that the trailer is secure before you crawl underneath it, and make sure that the boat is not on the trailer, as the weight will work against you. Remove the tires using the tire iron, and place them to the side.
Unbolt the leaf springs from the axle, using the 1/2-inch ratchet and socket. Then unbolt the front hanger of the leaf spring, using the 1/2-inch ratchet and socket, and slide the axle out from under the trailer with the help of an assistant.
Slide the replacement axle under the trailer with the help of an assistant, and set it on jack stands above the leaf springs. Bolt the front leaf spring hanger back to the trailer, using the 1/2-inch ratchet and socket, and mount the axle to the leaf springs, using the factory hardware and the 1/2-inch ratchet and socket.
Reinstall the tires, using the tire iron, and lower the trailer off of the jack stands, using the jack.
