How to Maintain a Trailer.

A high-quality trailer is a long-term investment. To ensure it remains safe, reliable, and road-ready, regular maintenance is essential. A little care can prevent costly repairs and dangerous situations on the road.

Here is a simple maintenance checklist you can follow.

1. Check Your Tyres

Tyres are the most common point of failure.

Tyre Pressure: Before every trip, check that your tyres are inflated to the pressure rating listed on the tyre wall. Under-inflated tyres can overheat and blow out.

Tread Wear: Look for uneven wear or low tread. This might indicate an axle alignment issue or that it's simply time for a new set.

Cracks & Damage: Inspect the sidewalls for any cracks, bulges, or perishing, especially if the trailer sits for long periods.

2. Inspect Wheel Bearings

Wheel bearings are critical for a smooth tow.

Listen: When towing, listen for any grinding or squealing noises from the wheels.

Feel: After a short drive, carefully feel the wheel hub. If it's extremely hot to the touch, your bearings may be failing or need grease.

Service: We recommend having your wheel bearings professionally repacked with grease at least once a year.

3. Test All Lights and Electricals

Working lights are a legal requirement.

Connect: Hitch your trailer to your car and turn on your headlights, then test your indicators (left and right) and brake lights.

Check Bulbs: Have someone stand at the back to confirm all lights are working.

Inspect Plugs: Check your trailer's plug and car's socket for any dirt, debris, or corrosion that could cause a bad connection.

4. Check Brakes (If Fitted)

If your trailer has a GVM over 750kg, it has brakes.

Electric Brakes: Test your in-car brake controller to ensure it's engaging the trailer's brakes.

Hydraulic Brakes: Check the brake fluid reservoir (if you have one) and look for any leaks in the lines.

General: Brakes should be serviced annually along with your wheel bearings.

5. Inspect the Coupling and Safety Chains

This is what connects the trailer to your vehicle.

Coupling: Ensure the coupling mechanism latches securely onto your tow ball and that the locking pin is in place.

Safety Chains: Check that the chains are not badly rusted, and that the D-shackles are rated and properly secured.

6. Look for Rust and Structural Damage

Frame: Do a quick visual inspection of the chassis, drawbar, and axles. Look for any significant rust spots, cracks in the welds, or bent frames.

Wash: Regularly washing your trailer, especially after exposure to salt or mud, is the best way to prevent rust.

By following this simple checklist, you can dramatically extend the life of your trailer and ensure every trip is a safe one.
