Measure bare or straight axles from tip to tip.

When measuring from the face of the axle, add 117mm to this measurement to get the tip of thread to tip of the thread length.

Other Common Parallel Axle Problems and Tips:

Poorly engineered square parallel axles will cause excessive bearing wear.

  1. Mismatched or rough seal journals can cause a loss of grease through the inner dimension of the rear seal.
  2. Examine the 45mm square parallel axle for cracks in the steel before installation. Some manufacturers supply non-virgin steel or scrap steel and forge this into solid square or round shape for axle production. Always ask for Australian Steel.
  3. 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.
  4. Are your tandem tyres wearing unevenly?

45mm Square Parallel Axle Tips.

Our quality parallel axles are what you need to tow your rig straight and true. Here are a few tips to improve your towing skills.

A known problem is jack-knifing Bobcat trailers while reversing which places excess pressure on the inner rear tandem tyre. Avoiding sharp turns will help to alleviate the problem.

The main reason this problem occurs is that some manufacturers rate their 45mm Square parallel axle near 1800kg per axle. While this rating is OK under normal conditions, it fails under reversing conditions.

If sharp turns are unavoidable when reversing then upgrade to a 2-tonne axle kit.

If your Square axle is bending, purchase a 50mm square axle and update to 2t. It is not very expensive in comparison to replacing springs that have suffered fatigue.
