Tow Bar Tow Hitch Coupling Maintenance & Replacement

Your trailer coupling is one of the most important parts of towing. It is the only part which connects your trailer to your tow-ball, so you need to be on top of maintaining it and ensuring it's in great condition.

How do I check my trailer coupling?

There are a few things to look at when inspecting your trailer coupling. Making sure the adjustment screw is correctly set is a great place to start. This screw ensures the coupling and tow ball keep a tight, strong connection while towing. Incorrect adjustment makes it difficult to connect the trailer or can result in the trailer becoming unattached during towing. This adjustment should be checked every 12 months, 10,000kms or anytime you replace the tow ball.

A visual check for any unusual looking wear inside the coupling where the tow ball sits is great practice too, as well a quick inspection of the entire unit to check for any serious rust, fatiguing or cracks in the housing. These simple visual checks should be carried out every time you use the trailer. If your visual inspections pick up any of the mentioned issues or your adjustment screw is maxed out, it's time for a new trailer coupling.
