what breaks on a DESC410R?

[RC John]

I'm new to the DESC410R, and would like to get spares for anything that routinely breaks. Besides arms, inner hinge pins, and rear bulkhead, are there anything else I should be aware of? I already have upgraded to aluminum suspension holders and aluminum gearbox holder.
Do the stock plastic rear gearbox inserts break? What about the front and rear hubs, and also the steering knuckle?
