Neglecting to use marine-grade grease, which can cause corrosion and premature failure.

Getting Started: A Step-by-Step Approach

Step 1: Gather Materials

New wheel bearings

Marine-grade grease

Torque wrench

Bearing packer

Step 2: Safety First

Park the trailer on a level surface and engage the parking brake.

Use wheel chocks to prevent the trailer from rolling.

Step 3: Remove the Wheel

Loosen the lug nuts, but do not remove them completely.

Use a jack to lift the trailer and remove the lug nuts and wheel.

Step 4: Remove the Dust Cap and Cotter Pin

Pry off the dust cap and remove the cotter pin.

Do not discard the cotter pin, as it will be reused later.

Step 5: Remove the Hub Nut

Grip the hub nut with a socket wrench and loosen it.

Do not remove the hub nut completely at this stage.

Step 6: Remove the Washer and Bearing

Remove the washer and old bearing.

Inspect the bearing for signs of wear or damage.

Step 7: Pack the New Bearing

Use a bearing packer to fill the new bearing with marine-grade grease.

Ensure that the grease is evenly distributed throughout the bearing.

Step 8: Install the New Bearing

Place the new bearing on the axle and press it into place.

Use the hub nut to tighten the bearing, but do not overtighten.

Step 9: Repeat the Process

Repeat steps 7-8 for the opposite wheel.

Step 10: Reinstall the Hub Nut, Washer, and Cotter Pin

Reinstall the washer and hub nut.

Tighten the hub nut to the specified torque.

Install the cotter pin to secure the hub nut.

Step 11: Reinstall the Wheel

Lift the trailer and reinstall the wheel.

Tighten the lug nuts, but do not overtighten.
