Automobile Steering Failure
Did
Axle Failure Wheel Loss Cause
SUV Rollover?
A metallurgical examination of an axle failure
was requested
to determine if the wheel loss caused an SUV rollover
or if the SUV rollover caused the wheel loss.
An overall view of the failed axle is shown in
Photograph A.
Photograph A: Overall
inside view of failed axle.
Visual and microscopic examination revealed that the axle failure was actually a steering
component failure caused by impact forces resulting from the SUV rollover. No metallurgical or manufacturing defect was found to account for pre-accident failure of the SUV axle.
