Common Semi-Trailer Issues You Should Watch For

Semi-trailers are built for durability, but their heavy usage means they're-they're no strangers to problems. Here's a breakdown of the most frequent issues and how to address them:

1. Brake System Problems

The brake system on a semi-trailer is critical for ensuring driver and cargo safety. Given the hefty loads commercial trailers carry, brake issues can be dangerous if not addressed.

Causes:

• Excessive wear and tear: Frequent stops with heavy cargo can accelerate brake wear.
• Air pressure issues: Semi-trailers use air brakes, and leaks or faulty compressors can lead to malfunction.
• Corrosion: Exposure to road salt, especially during Hackettstown winters, can damage brake components.

Signs to Watch For:

• Squeaking or grinding sounds.
• Longer stopping distances.
• Uneven brake pad wear.

Solutions:

• Regular inspections: Schedule inspections to check the condition of the rotors and brake pads. The airlines are in good condition.
• Repairs and replacements: Replace worn-out brake pads and fix air pressure leaks promptly.

2. Tire Wear and Maintenance

Tires are another component that withstands significant stress, especially given the long distances the semi-trailers cover.

Common Problems:

• Uneven tread wear due to misalignment or poor inflation.
• Overloading or old tires cause frequent blowouts.

Maintenance Tips:

• Check tire pressure frequently: Underinflated tires can cause dangerous driving conditions.
• Rotate tires regularly: This ensures even tread wear.
• Timely replacements: Don't wait for the tread to become dangerously low.

Taking these precautions can extend tire life and prevent costly replacements.

3. Electrical System Malfunctions

Electrical problems can cause severe disruptions, especially when they impact lighting systems or trailer controls.

Symptoms:

• Dim or non-functional trailer lights (brake lights, turn signals, etc.).
• Malfunctioning ABS warning lights.
• Issues with power lines connecting the trailer to the truck.

Fixing Electrical Issues:

• Inspect and clean electrical connectors regularly to prevent corrosion.
• Replace damaged wires or fuses immediately.
• Use diagnostic tools to identify deeper electrical issues.

4. Suspension Problems

The suspension system of a semi-trailer ensures smooth rides and protects cargo from damage. Over time, suspension components can deteriorate, resulting in bumpy rides and unsafe handling.

Signs:

• Visible sagging or uneven trailer height.
• Excessive bouncing or poor handling on uneven terrain.
• Unusual noises during operation.

Repairs:

• Check and replace worn-out components such as bushings or shocks.
• Apply lubricant to trailer moving parts to minimize wear and tear.

5. Structural Damage

The structural integrity of a semi-trailer is essential for both safety and functionality. Overloading, collisions, or neglect can damage the structure.

Inspections:

• Look for cracks, dents, or corrosion in the chassis or body.
• Perform routine checks after long hauls or accidents.

Repairs:

• Address minor problems promptly to prevent them from escalating.
• Use certified professionals for welding or structural restorations when necessary.

Preventative Maintenance Keeps Your Fleet Moving

Preventative maintenance is the best way to avoid costly repairs and keep your semi-trailers in shape. Here's what to focus on:

• Frequent inspections: Regular checks help identify minor problems before they become major.
• Fluids and lubricants: Ensure all necessary fluids (brake fluid, hydraulic oil, etc.) are optimal.
• General cleaning: Especially in Hackettstown, seasonal road salt can accelerate rust and corrosion.
• Professional servicing: Partner with a reliable maintenance shop for comprehensive services.

Regular preventative maintenance and addressing issues early can significantly extend its lifespan. To make the most of your trailers, stick to a strict service schedule and invest in quality repairs.
