Troubleshooting Common Brake Issues

Spongy Brakes: This can indicate air in the brake lines. Bleed the brakes to remove air.
Brake Drag: This can be caused by a stuck caliper or a faulty brake actuator. Inspect and repair as needed.
Excessive Wear: This can be caused by improper braking habits or a faulty brake system. Ensure brakes are adjusted correctly and functioning properly.

4. Wheel Bearing Maintenance: Smooth Sailing

Wheel bearings are critical components that allow your trailer wheels to spin freely. They are subjected to significant stress and require regular maintenance. Here’s a detailed guide:

Bearing Inspection

How to Inspect: Jack up the trailer and grab the top and bottom of each tire. Rock the tire back and forth, feeling for any play or looseness. If there is play, it could indicate worn bearings.
Visual Inspection: Look for signs of grease leakage around the wheel hubs, which could indicate a failed seal.

Bearing Repacking Steps

Preparation: Gather necessary tools and materials, including a grease gun, wheel bearing grease, a hammer, a punch, and new seals. Always consult your trailer's manual for specific instructions and recommendations. Ensure the trailer is safely supported using jack stands.
Removal: Remove the wheel, then the grease cap, cotter pin, and castle nut. Carefully pull off the hub, keeping all components in order. Place the bearings, washers, and other parts on a clean surface.
Cleaning: Clean the bearings thoroughly with solvent or brake cleaner to remove all old grease. Inspect the bearings for any signs of damage, such as pitting, discoloration, or wear.
Greasing: Pack the bearings with fresh grease using a bearing packer or by hand. Make sure the grease fully penetrates the rollers.
Reassembly: Reassemble the hub, ensuring all components are in the correct order. Torque the castle nut to the manufacturer’s specifications, then back it off slightly to allow for free spinning. Install a new cotter pin and grease cap.

Troubleshooting Common Bearing Issues

Grinding Noises: This often indicates a worn or damaged bearing. Replace the bearing immediately.
Overheating: This can be caused by a lack of grease, a damaged bearing, or improper adjustment. Inspect and repair the bearing system as needed.
