Connected to the lower strut mount of my Mazda Protege 2002 is a "wing" which leads away with a size 14mm bolt in it. I have been trying to loosen the rusted bolt, but I can't get it loose. I am wondering what the function of the connected system is and the impact if I have to cut the strut loose instead (and thus can't reconnect this system).
I've circled the bolt in red.
I have found diagrams that show this part, but no labels are included for what this system may be. I really appreciate any help!
