How to Change Wheel Bearings on a Trailer?

It is important to keep your wheel bearings in condition for reliable towing. These components can wear out, especially when transporting heavy goods or travelling long distances. Knowing how to change wheel bearings on a trailer is very handy if you experience an unexpected breakdown. Plus you don’t have to visit a workshop every time, saving you both money and time. This guide teaches you how to change your trailer’s bearings. If you’re a DIY enthusiast or somebody looking to learn the basics, this is a must-read. So, let’s dive right in.

Every proper maintenance or replacement process requires the right equipment. Before you begin, make sure you have these tools at hand.

• Jack
• Hammer
• New bearings
• Bearing grease
• Wrench set

Here’s how the whole thing works:

• Lift the Trailer:

  Park your trailer on a flat surface and engage the parking brake so that it stays in place. Use a jack to lift the trailer. Ensure it is stable before proceeding with the next steps. This will give you access to the wheels and facilitate their easy removal.

• Remove the Wheel and Hub:

  Next, remove the wheel by loosening the nuts using a wrench. Once it’s off, pull out the dust cap in the centre of the hub as well as the cotter pin and adjusting nut. Now you can slide the hub to work on the bearings inside.

• Inspect the Bearings:

  Knowing how to inspect wheel bearings for any signs of rust, wear, or damage is important. This helps you make preventive decisions in time. If the bearings look corroded or damaged, they should be replaced. Sometimes, you may only need to clean and re-grease them. However, if you’re doubtful, installing new bearings is the best choice.

• Remove Old Bearings and Clean the Hub:

  Once the hub is removed, you’ll find the trailer wheel bearings. Remove them and wipe away all the old grease. Clean the hub thoroughly to ensure no dirt is left, which can cause problems with the new bearings.

• Install New Bearings:

  With the hub completely clean, you can install new trailer bearings. Make sure to apply a generous amount of grease on them for lubrication. Gently push the bearings into the hub and make sure they fit snuggly.

• Reassemble the Hub and Wheel:

  After new bearings have been fitted, secure the hub back on the axle using the nuts and pin. Make sure they are screwed on correctly to prevent any slack while driving. Next, replace the dust cap on to protect the bearings from dirt and debris. Finally, reinstall the wheel, tighten the nuts, and lower the trailer back onto the ground. Always double-check the wheel to ensure everything is secure before hitting the road again.

• Test the Bearings:

  Once everything is done, test the trailer before going anywhere. Gently spin the wheel, and if you hear any unusual noises or feel any resistance. If the wheels spin smoothly and are quiet, the new bearings have been installed correctly and your trailer is ready. This simple check lets you know the bearings are working as intended.

Knowing when to change trailer wheel bearings plays an important part in maintenance. Depending on factors like trailer type, use, signs of wear, or overheating brakes, the intervals may vary. A good tip would be to change the bearing every 6 months or 10,000-12,000 kilometres, whichever comes first. However, if you hear unusual or grinding noises when towing, it’s time for a closer look at the bearings.

Regular checks are necessary to help keep your trailer in top shape. Greasing the hub6 and bearings keeps them lubricated, protecting them from wear and tear. Proper lubrication increases bearing life and allows the trailer to run smoothly. If you haul heavy loads or hit the road frequently, it’s a great idea to have a trailer wheel-bearing kit with you. This can be a lifesaver, especially when faced with unexpected issues.
