Broken Axle Shaft

Inspect a broken axle shaft for a twist in the spline next to the brake.

Breaks that occur away from the spline or that are not accompanied by a twist in the spline can be caused by forging flaws or fatigue of the axle shaft.

Conditions that can cause a broken axle shaft include forging flaws or excessive impact load to the axle shaft as a result of a collision or other factors.
