When our trailer axle is damaged, we need to replace the new trailer axle in time to avoid some accidents. Then the following are the specific steps to replace the trailer axle.

Maximum load per trailer axle can be found on the trailer's vehicle identification tag. Along with the weight rating, there are a few measurements to be taken to order the new trailer axle parts.

The trailer axle length should be measured. If the wheel hubs have already been removed, the overall length from tip to tip can be taken. If the wheel hubs are still in place, the trailer axle should be measured from hub face to hub face. 

The spring seat center measurement should be taken. If the leaf springs are still installed, the measurement should be taken across the trailer axle, from center to center on the leaf springs. If the springs are not installed, measure from center to center on the spring pads. 

Using these measurements, a replacement trailer axle can be purchased. It is also a good idea to replace all associated mounting hardware and to recycle the old hardware. If the wheel hubs have not been serviced or replaced recently, show visible signs of wear or damage, or are making noises indicative of worn bearings, this would be a good time to replace them since they have to be removed anyway.

With all-new parts in hand, it is now time to install the trailer axle kits. This is best accomplished with the help of another person to help lift and move the trailer axle.   

(1)Start by loosening the lugs nuts on both tires.

(2) Raise the trailer using a hydraulic jack, and secure it on jack stands at four points. With the trailer securely resting on the jack stands, remove the tires and set them aside. If the trailer is equipped with brakes, disconnect the brake lines and take care to ensure the lines do not get snagged during the removal of the trailer axle. If the trailer is equipped with shocks, disconnect the lower shock mount from the trailer axle and set the mounting bolt aside. Inspect the shocks for leaks or worn mounting grommets and replace them if they are worn. 

(3)Remove the wheel hubs and brake hardware and set them aside. The trailer axle is secured to the leaf springs with a U-Bolt. Remove the U-Bolts on both ends of the trailer axle, and the trailer axle should be completely disconnected from the trailer. With an assistant on the other end of the trailer axle, lift and move it to the side until completely free of the leaf springs. Once clear of the springs pull the trailer axle all the way out from under the trailer. Installation of the new trailer axle is simply the reverse of the removal process. Slide the trailer axle under the trailer and position it so the leaf springs rest on the spring seats. Using new hardware, bolt the trailer axle in place, and reconnect the shock absorbers if applicable. Reinstall the wheel hubs and brake assembly, and reconnect the brake lines.

(4)Install the wheels and lower the trailer from the jack stands. Be sure to check brakes for proper function, and the job is complete.
