What are the causes of Reaction Wheel Failures/Anomalies?

Question

What are the mechanisms of reaction wheel anomalies? Are there any fish bone or fault tree analyses on these issues?

Answer 1

I'm going to presume that a related question linked in the comments answers the first part of the question and will focus on the latter part of it as a reference request follow-up to the linked one. Since no specific mission's methodology was inquired about, here are some arbitrarily selected publications on the topic of fault detection and management:
