45mm Axles may be perfect for your trailer, caravan or camper. If you are having problems towing your rig straight and true, then we have a few tips for you below.

Round Axle Common Problems:

  • Too much weight will bend this Round Axle which will result in excess axle flex. Axle flex occurs when a heavily laden trailer spring rebounds on the highway causing the 45mm round axle to flex up and down, or vibrate in the middle.
  • Springs fatigue can cause premature failure under axle flex or overload conditions. Once your load is over 1450kg you will start to experience axle flex.
  • Axle flex and spring failure can occur if you have incorrectly selected a solid or hollow axle for your application.

If the axle is bending, purchase a 45mm square axle and update to 1.5t. It is not very expensive in comparison to replacing springs that have suffered fatigue.

Other Common Problems:

  • Poorly engineered 45mm round axles can result in excessive bearing wear.
  • Are your tandem tyres wearing unevenly? Here is a link that provides the correct method to test your axles.
  • Before replacing your 45mm round axle, examine it for cracks in the steel. Some suppliers supply non-virgin steel or scrap steel and forge this steel into solid square or round shape for axle production.
  • Chinese bearings are the second biggest cause of axle failure. If you plan driving on the highway, use Japanese bearings. The combination of Japanese Bearings and Couplemate axles will help you significantly lower maintenance for your rig.

Solutions To Axle Problems:

  • You should upgrade 6 stud Landcruiser axles to a parallel axle configuration.
