Trailer Inspection: What You Need to Know

By M&G Trailer Sales April 12, 2022 Service/Maintenance

Both business owners and recreational trailer owners should complete an annual trailer inspection to ensure their trailer is up to snuff. Just like trucks and other tools, trailers face wear and tear over time that may cause trailer safety and reliability issues. The inspection requirements vary by state, but there are a few parts of your trailer that everyone should check – regardless of state regulations.

You can find more information on Minnesota’s truck and trailer requirements and inspections on the state’s website.

Proper At-Home Trailer Inspection

Hitch and Coupler

The trailer hitch mounts and ball will likely be beat up after a year or so of use. During routine trailer inspection, you should check to make sure the frame mounting bolts are tight and check that there are no cracks. Next, check the trailer coupler to ensure the jaw fits tight over the tow ball and that the safety latch is securely pinned.

Another quick trailer safety check for trailer hitches is the weight restrictions. Each ball and hitch has a weight safety regulation. You can find these restrictions on the internet or in an owner’s manual. Following these weight restrictions are essential to safely towing and using your trailer.

Lighting and Wiring

The first step of checking lighting and wiring is simple. Test the brake lights and turn signal to make sure they work. Next, check the trailer plug. Examine the receptacle and plug to look for any frayed or loose wires. You can bring your trailer into M&G for help with trailer service, like repair or replacements in trailer wiring. If everything looks good, you should still take the time to clean the plugs and wiring.

Additionally, an inspection should include checks on the trailer reflectors. Trailers built after 1968 should have red and amber reflectors on the back and side, depending on the trailer length. You can consult a trailer maintenance representative to be sure your trailer reflectors meet state and federal regulations.

Tires

Tire checks are an essential part of trailer inspection. Over-inflated or under-inflated tires wear out more quickly and are more likely to cause accidents. To help your tires last longer, we recommend checking the tire pressure on both the tow vehicle and trailer at least monthly. You can adjust the tire pressure as necessary.

Aside from pressure, you should check the tread on your tires. If they’re worn down, bring your trailer by M&G for a replacement. Then, double check the lug nuts to ensure they’re tightly secured.

Brakes and Wheel Bearings

The next step to trailer inspection is checking the brakes. Brakes are an essential part of trailer safety. Though the tow vehicle brakes will be doing the bulk of the work when braking, the trailer brakes are important for emergency situations.

After you check the brakes, you should check the wheel bearings. Replace or repack them about twice a year.

Springs and Axles

Aside from the hitch and ball, the trailer’s springs and axles will take the most abuse. During a routine trailer inspection, examine the springs and axle(s) for damage, and let M&G repair or replace them as needed. Bent or misaligned axles will easily further damage your trailer and can lead to safety hazards on the road. Finally, check the mounting bolts for proper tightness.

Plates

The final step of a routine trailer inspection is checking the license plate. The plate on your trailer should be hung horizontally and be easy to see, even when your trailer is full. Make sure the plate is tightly fastened and illuminated, especially at night.

Once all of these steps are completed, your trailer inspection is over. Although, we do recommend bringing your trailer in for an expert inspection at M&G Trailers.
