Preventative Maintenance Tips to Avoid Expensive Trailer Repairs

We barely think about trailers when talking about heavy duty equipment maintenance. Trailers are designed to be sturdy and do not require too much maintenance unlike other equipment. However, repairing a trailer, as you would expect, is a very expensive endeavour. This is where preventative maintenance comes into the picture. World Diesel perform many trailer repairs in Perth, Western Australia. In this post, we are going to mention a few preventative maintenance tips to avoid costly trailer repairs and keep it running long even after the warranty expires.

Clean the Trailer

Perhaps this is the most obvious maintenance tip, but it is worth mentioning. If you live in a cold climate trailers are usually coated with chemicals during the winter season to keep the internal parts from freezing, but you should not forget to clean off these chemicals during spring time. That’s because they can take a toll on the wiring and even corrode the metal parts of the vehicle. If you’re transporting soil or anything else that can hold moisture, this can cause rust, so this should also be cleaned immediately after use.

Inspect The Tire Inflation

As with any other vehicle, the ideal tire pressure can save you a lot of money in terms of mileage. Deflated tires tend to put some additional strain to the engine, causing it to use more fuel than required. Not only that, deflated tires also wear quickly and easily and may call for replacement sooner than you think. So, always ensure your trailer tires are properly inflated before driving.

Keep an Eye on The Seals

Moisture leaking into the trailer through faulty weather stripping and seals is a common issue. Seals tend to degrade over time, and some brands are known for not using ideal seals to begin with. When they start to break down, they allow water seepage, thus damaging the surfaces and creating an ideal environment for mold growth. So, check the seals around the doors and windows every few months to avoid deterioration. Also, keep an eye out for water stains, loose pieces and cracks. Even the smallest of cracks can pave way for water. You can ideally consider resealing the trailer periodically to be on the safe side.

The Brakes

Brakes are without a shadow of doubt, an important part of trailer maintenance. Accidents are not uncommon and brakes failure is usually the cause. So, pay attention to the angle between the slack adjuster and the air chamber push rod. You are looking to a right angle, otherwise, the brakes require re-adjusting.


A properly lubricated trailer will certainly last longer. Friction between moving parts is one of the major causes of wear and you can slow this down by regularly lubricating the components of the vehicle.

Get Regular Checkups

It does not have to be too often and it does not have to be thorough, but having your trailer checked once in a while is a good idea. Auto repair professionals can give you indispensable tips and advice after taking a look at your vehicle. This information could save you from incurring an expensive repair.

The best trailers have low maintenance costs and run for long even after the warranty expires. So, practice these tips and you will enjoy an optimally working vehicle for a long time.
