Trailer U-Bolt Maintenance

Another essential piece of the puzzle when it comes to towing is your U Bolts. U Bolts keep your trailer on the frame and axles, If these fail due to corrosion or damage then your caravanning holiday or boat trip is over.

How do I check my U Bolts? Checking U Bolts is similar to checking any other fastener. Check that the nuts on your U Bolts are torqued correctly with a good quality torque wrench. Even if they look tight, any movement or vibration can sheer U Bolts due to the amount of weight that they are holding over rough surfaces. If you notice any stretching or damage of the threads, rust, or wear between contacting parts or any evidence of cracking or stress marks, a set of replacement U Bolts is a small price to pay to potentially save your trailer. Thanks to their low cost, U Bolts are a great part to replace if you're unsure about the above.

When replacing your U Bolts, we recommend fitting galvanised units such as the Repco U Bolts due to their corrosion resistance for greater life. This is particularly necessary on parts which sit outside and are exposed to constant road grime or even saltwater at the boat ramp.
