Before embarking on this task, ensure you have the following tools and parts at hand:

Tools	Parts
Jack	Wheel bearing kit
Lug wrench	Grease gun
Wheel chocks	New bearing seal

2. Safety First

Park your trailer on a level surface and engage the parking brake. Place wheel chocks behind the wheels opposite the one you'll be working on.

3. Remove the Wheel

Use the lug wrench to loosen the lug nuts. Raise the trailer with the jack and detach the wheel.

4. Remove the Old Bearing

Carefully remove the hubcap, cotter pin, and castle nut. Using a hammer and drift, gently tap out the old bearings.

5. Inspect the Hub and Axle

Clean and inspect the hub and axle for any damage or corrosion. If any issues are found, seek professional assistance.

6. Install the New Bearing

Pack the new bearing with grease and slide it onto the axle. Secure it with the castle nut, cotter pin, and hubcap.

7. Reattach the Wheel

Place the wheel back on the hub and tighten the lug nuts securely.

8. Grease the Bearing

Using a grease gun, apply grease to the zerk fitting on the hub.

9. Check the Alignment

Once all the wheels are back on, check that they are properly aligned. This will ensure even wear and optimal performance.

Common Mistakes to Avoid

Overtightening the castle nut, leading to premature bearing failure.

Failing to inspect the hub and axle for damage, potentially causing further issues.

Neglecting to grease the bearing, resulting in reduced lifespan and increased friction.
