A twisted (or broken tube) shows excessive load or undersized shaft. Stock tubes are usually very weak.

Sheared Tube​

A tear in the tube can be caused by something rubbing on the shaft creating stress risers. 

Broken U-Joint

This is usually a result of excessive angles, shock load or poor quality.

This causes twisted tubes - warning sign are cracks in the paint or scaling of the surface oxide.

Broken Weld

Can be caused by a defective weld, over-heated weld, or even inconsistent properties in the tube.
