I'm inspired mostly by SKINNEDR's post to offer these comments as food for thought.

Any time a part fails you need to discover the underlying reason and fix that too. Occasionally you will find a failed part that was simply not well constructed or not intended to take the forces applied to it; but if you replace it with one just like it, it will likely fail too. Of course replacing the failed part with a stronger one may lead to you discovering the next weakest link in the chain of parts that is a car.

For those who may not know, Grade 8 is not always better than Grade 5 for all applications. In simple terms, as forces build on a bolt, a Grade 5 may bend and deform before a Grade 8. But as the force build more, the Grade 8 may snap while the Grade 5 only deforms more. The question of which is better depends on the application. In some cases its better to have a bent bolt than risk having a snapped one.

Lastly, I used to take my car to the track, so I have seen lots of failed parts and systems. I look at each failure as an opportunity to make the car better than before. My goal is to fix each failure such that it will not happen again.
