A guide to analysis and correction of premature engine bearing failures

As you know, every automotive engine part will eventually wear out. And if every part always performed for the full length of its expected life, your job would be fairly simple. . . to replace parts that have worn. Unfortunately, we cannot always count on an engine part failing only because its normal lifespan is exceeded. A mechanic must not only be a “replacer of parts” but, like a doctor, he must be capable of diagnosing his “patient” to deter- mine why a part failed prematurely.

This linked PDF provides a pictorial analysis of the most common causes of bearing failures.
