The only real problems come from imported steel causing steel fractures along the beam and in the consistent hardness of the beam.
Other Common Problems and Tips:
If your 50mm square parallel axle is not properly engineered you may experience excessive bearing wear.
- Rough seal journals can cause a loss of grease through the rear seal.
- Some suppliers supply non-virgin steel or scrap steel and forge this steel into solid square or round shape for axle production. Always ask for Australian Steel.
- Chinese bearings are the second biggest cause of axle failure.
- If you plan to get onto a highway, use Japanese bearings.
- The combination of Japanese Bearings and 50mm Square Axle will help you greatly with lower maintenance for your rig.
