Good, I try not to get into theological discussions especially with friends and/or fanatics (both apply in this case).
IMHO that plastic part of the Fixed Cam Assembly is there to hold the thing together and nothing else.
When it is in its proper operating place on the truck within the Auto Hub Assembly attached to the wheel hub it is practically pressed from all sides. It is locked into the spindle and does not turn with the wheel or the axle. When operating correctly and as intended it is, from what I can surmise, not subject to any type of stress beyond what the spring that it holds can put upon it when it is operating (locking and unlocking). If you have ever taken the Fixed Cam Assembly apart you have realized how fragile it is and how it will misshape or break with just the slightest bit of force.
I suggest that it breaks because of wear caused by one or a combination of the following;
prolonged overuse that could include the rocking (locking and unlocking).
improper lubrication (too much/too little)
contamination, dirt, water.
heat caused by any of the above or any extreme temperature (hot and/or cold) can break down the composition of the plastic making it too brittle or too pliable.
negligent; all of the parts in our trucks need to be somewhat maintained...nothing last forever.
I restate the theory that

The only other material I would think they could make that part out of would be stamped steel. I'm thinking they used plastic to keep the thing quiet..
At this point, with my adamantly limited knowledge I disagree with all and any statements that refer to the plastic part of the Fixed Cam Assembly as a "fuse" in any sense of the word for anyone in any situation.
Convince me otherwise...
