Trailer Maintenance 101: Keep Your Rental in Top Shape

07, Aug, 2025

Here’s a beginner-friendly guide to keeping your trailer in top shape!

Inspect the Trailer Before and After Each Use

A quick inspection before and after every trip can catch small issues before they become major problems. Check for loose bolts, cracks, or rust on the frame, and make sure nothing is hanging or dragging underneath. Look for signs of wear and tear on the tires, lights, and hitch.

After a long trip, clean off mud, road salt, or debris, as these can cause corrosion over time. Keeping the trailer clean also makes it more attractive to potential renters.

Check the Tires and Maintain Proper Pressure

Trailer tires wear out faster than vehicle tires, especially under heavy loads. Low tire pressure increases the risk of blowouts, poor handling, and extra fuel consumption.

Before towing, check the tire pressure and inflate them to the recommended PSI. Inspect for cracks, uneven wear, or punctures, and replace old tires when the tread wears thin. If the trailer is sitting unused for long periods, move it occasionally to prevent flat spots.

Lubricate Moving Parts to Prevent Rust and Wear

A trailer has many moving parts that require lubrication to function smoothly. Apply grease to wheel bearings, hinges, jacks, and the coupler to prevent squeaking, friction damage, and rust.

If the trailer will be stored for a long time, lubricate exposed metal parts to protect them from moisture and corrosion. Using rust-preventive sprays or grease can extend the life of key components.

Test Lights and Electrical Connections

A malfunctioning trailer light can lead to accidents, fines, or towing hazards. Before every trip, test the brake lights, turn signals, and reflectors to ensure visibility on the road.

If a light isn’t working, check for blown fuses, loose wiring, or corrosion in the connectors. Applying dielectric grease to electrical connections helps prevent moisture damage and ensures a strong connection.

Keep the Brakes in Good Condition

If your trailer has electric brakes or hydraulic surge brakes, they need regular inspection to stay in top condition. Worn-out brake pads can lead to longer stopping distances and unsafe towing.

Listen for squeaking or grinding noises when braking, as these may indicate worn pads. Also, check the brake fluid levels and look for leaks in the brake lines.

Secure the Hitch and Safety Chains

A trailer hitch is the most important connection between the tow vehicle and the trailer. Before driving, double-check that the hitch is securely latched and locked in place.

Safety chains should be crossed under the hitch to create a cradle in case of accidental detachment. If the trailer has a breakaway system, test it periodically to ensure it functions properly.

Store the Trailer Properly When Not in Use

If your trailer is sitting idle, proper storage can prevent unnecessary damage. Park it on concrete or gravel to reduce moisture exposure, and use a trailer cover to protect it from harsh weather.

If possible, elevate the front jack to keep the weight off the tires and prevent flat spots. For long-term storage, remove the battery and store it separately to avoid draining power.

Final Thoughts

Keeping a trailer well-maintained ensures safe and reliable performance, whether you’re renting it out or using it yourself. Regular inspections, proper lubrication, tire checks, and electrical testing will help prevent costly repairs and keep your trailer road-ready.
