Practical Tip: Always use high-quality bearings and grease to ensure longevity and performance.
Step 2: Prepare the Trailer
To safely work on the trailer, follow these steps:
- Park on a Level Surface: Ensure the trailer is on a flat, stable surface to prevent any accidents.
- Lift the Trailer: Use a jack to lift the trailer and secure it with jack stands to keep it stable while you work.
- Remove the Wheel: Unscrew the wheel nuts using a socket wrench and remove the wheel from the axle.
Common Pitfall: Ensure the trailer is securely lifted before beginning work to avoid any injury.
Step 3: Remove the Old Wheel Bearings
Follow these steps to access and remove the old bearings:
- Remove the Dust Cap: Use a screwdriver to pry off the dust cap from the hub.
- Take Out the Cotter Pin: Locate the cotter pin holding the axle nut in place and remove it with pliers.
- Unscrew the Axle Nut: Use a socket wrench to unscrew the axle nut. Keep the nut and washer for reinstallation.
- Remove the Hub: Carefully slide the hub off the axle to access the bearings.
Step 4: Inspect the Components
After removing the hub, inspect the following:
- Wheel Bearings: Check for any signs of damage or wear. If they feel rough or have play, they need to be replaced.
- Spindle: Ensure the spindle is clean and free of any debris or damage.
Practical Tip: Clean all components thoroughly with a suitable cleaner before reassembly.
Step 5: Install New Wheel Bearings
Now that the old bearings are removed, proceed to install the new ones:

- Insert Bearings: Place the new bearings into the hub.
- Reattach the Hub: Slide the hub back onto the axle carefully. Ensure it fits snugly.

- Reinsert the Cotter Pin: Insert a new cotter pin through the axle nut and bend it to secure it in place.
Step 6: Final Assembly
Complete the reassembly of the trailer:
- Reattach the Dust Cap: Firmly press the dust cap back onto the hub.
- Reinstall the Wheel: Align the wheel with the hub and screw it back on using the wheel nuts. Tighten them in a crisscross pattern for even distribution.
- Lower the Trailer: Carefully remove the jack stands and lower the trailer back onto the ground.
