How to Properly Inspect and Maintain Your Trailer

At BM Galaxy Inc. Truck & Trailer Repair, located in the heart of Cincinnati, OH, we understand the importance of regular trailer inspections and maintenance. Whether you’re hauling heavy loads cross-country or just making short local trips, your trailer's condition directly impacts your overall operational efficiency. Here's a guide to help you keep your trailer in top shape.

Why is Regular Trailer Inspection Important?

Trailers endure significant wear and tear due to constant exposure to the elements and the weight they carry. A neglected trailer can lead to unexpected breakdowns, costly repairs, or even accidents. Regular inspections help catch minor issues before they escalate into major problems. This proactive approach not only saves money but also keeps your trailer compliant with DOT regulations.

The Essential Trailer Inspection Checklist

Conducting a thorough inspection involves a series of checks that cover different aspects of the trailer. Here’s what you should look for:

Tires and Wheels

Your tires are your first point of contact with the road, making them one of the most critical components to inspect. Start by checking the tire pressure and tread depth. Uneven tread wear could indicate alignment issues or improper load distribution. Also, inspect the wheel rims for cracks or damage.

Braking System

A trailer's braking system is vital for ensuring that you can stop safely and effectively. Check the brake pads, rotors, and drums for wear and tear. Ensure that all brake lines are intact and free of leaks. We recommend testing your brake response regularly to ensure they're functioning correctly under load.

Lighting and Electrical System

Faulty lights are a common reason for DOT violations. Inspect all lights, including brake lights, turn signals, and clearance lights, to ensure they are working correctly. Also, check the wiring for signs of wear, corrosion, or loose connections.

Suspension System

The suspension system bears the weight of your cargo and absorbs shocks from the road. Inspect the leaf springs, hangers, and U-bolts for signs of wear or damage. Any cracked or broken components should be replaced immediately to avoid compromising the trailer’s stability.

Frame and Chassis

The frame and chassis provide structural integrity to your trailer. Look for any signs of rust, cracks, or deformities. Pay special attention to the areas around welds and joints, as these are often stress points that can fail under load.

Hitches and Couplings

Ensure that the hitch and coupling systems are secure and free from excessive wear. Check that the safety chains are in good condition and properly attached. A faulty hitch or coupling can result in the trailer detaching from the truck, leading to catastrophic consequences.

How Often Should You Perform These Inspections?

Regularity is key when it comes to trailer maintenance. Here’s a basic guideline:

• Pre-trip Inspection: A quick check before every trip can help catch obvious issues like low tire pressure or malfunctioning lights.
• Monthly Inspection: A more thorough inspection, including checking the brakes, suspension, and frame, should be conducted at least once a month.
• Annual Inspection: A full inspection and service should be performed by a professional annually to ensure all components are in optimal condition.

Common Issues Found During Trailer Inspections

What causes trailer tires to wear out quickly?

Tires are susceptible to several issues that can cause rapid wear:

• Overloading: Exceeding the trailer’s weight capacity puts extra strain on the tires, leading to faster wear.
• Improper Inflation: Both under-inflated and over-inflated tires can cause uneven wear patterns. Regularly check and maintain the correct tire pressure.
• Misalignment: If the axles or wheels are not aligned properly, the tires will wear unevenly. This can also affect the handling of your trailer.

Why are my trailer brakes squeaking?

Squeaking brakes are often an indication that something is wrong. Common causes include:

• Worn Brake Pads: Over time, brake pads wear down and begin to squeal as a warning that they need to be replaced.
• Glazed Pads or Rotors: If your brakes have overheated, the pads or rotors can become glazed, leading to squeaking.
• Lack of Lubrication: Components like calipers and sliders need to be properly lubricated to function smoothly. If they dry out, you may hear squeaking.

Preventive Maintenance: The Key to Longevity

Preventive maintenance is the best way to avoid costly repairs and downtime. It involves routine checks and services designed to keep your trailer running smoothly. We recommend the following preventive measures:

• Regular Lubrication: Keep all moving parts well-lubricated to reduce friction and prevent premature wear.
• Timely Replacement of Worn Parts: Replace any worn or damaged components before they fail completely. This includes brake pads, tires, and suspension parts.
• Rust Prevention: Apply rust inhibitors to the frame and other exposed metal parts to prevent corrosion, especially if your trailer is frequently exposed to moisture.

How do I prevent trailer electrical issues?

Electrical issues can be a headache, but they are often preventable with proper maintenance:

• Keep Connections Clean: Dirt and corrosion are the enemies of electrical systems. Regularly clean all connections and apply dielectric grease to prevent corrosion.
• Inspect Wiring Regularly: Look for any signs of fraying or damage in the wiring. Replace any compromised wires immediately.
• Test Lights Frequently: Before hitting the road, always test all your lights. It’s a quick check that can save you from a costly ticket or accident.
