Greetings. I recently got under my vehicle to replace my rear sway bar and noticed that another part was extremely rusted/deteriorating. By deteriorating, I mean that it rotted through the core in some spots. After doing my research, it turns out to be the Suspension Rear Stay Arm (OEM part# 55451-EG010). I already have one on order but was wondering if anyone could tell me the purpose of this part and if it's still safe to drive the vehicle? I want to go out and enjoy my new suspension mods but not if the faulty part could place me in great danger. Thanks!
