Rubber bushings do have hysteresis, but let’s not get into that now.

Stiction- I am familiar with, as I set up my own suspension on my motorcycle. Hysteresis (thank you) is the proper word, I believe, for what I was trying to describe- the twisting deformation of a bonded rubber bushing.
My understanding is that in the broadest, most general sense, any component that will increase the force that is required to move a suspension component through its envelope of travel, where the force required increases as travel increases, essentially becomes a spring, and is not a damper. Exceptions do exist, such as dampers that increase compression damping close to the limit of travel.
Yes, let’s not get into it! I’m sticking with rubber (pun intended).
nickelplated5s- exactly.
