Getting Started

Gather necessary tools: wrenches, sockets, grease gun, bearing puller, bearing packer

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

Remove the wheel and tire

Remove the hub assembly from the spindle

Use a bearing puller to remove the old bearings

Step-by-Step Approach

Inspect the spindle and hub assembly: Check for any damage or wear that may indicate additional issues.

Clean the surfaces: Remove all old grease and dirt from the spindle, hub, and bearing races.

Apply new grease to the spindle and inner race: Fill the inner race and spindle with a high-quality marine grease.

Install the inner and outer bearings: Use a bearing packer to evenly distribute grease around the balls or rollers.

Install the hub assembly: Slide the hub assembly back onto the spindle and align the bearings.

Tighten the castle nut: Gradually tighten the castle nut while rotating the wheel to ensure proper alignment.

Install the cotter pin: Insert the cotter pin through the hole in the castle nut to secure it.

Common Mistakes to Avoid

Overtightening the castle nut: This can damage the bearings and cause premature failure.

Using incorrect or contaminated grease: Marine grease is specifically designed for boat trailer bearings.

Neglecting to inspect the spindle and hub: Worn components can lead to bearing damage.
