What is the name of these Driver Side Suspension links?

Here is a video so you can have a closer look. I hope this helps. I believe they’re both 16s but then again might be 2s. I can’t tell but I hope this video can help us.
I think you are correct in me needing an alignment once that is touched. That’s fine, my tire shop is close. However, there are 2 separate links that need replacing, hence the two photos. Please help me differentiate if they are the same part and which part they are. Thank you.

Hi Joe. Yes, one is a lateral link. Everyone I have asked can only see that the other bar is called a control arm as well, but it isn’t exactly that. I cannot find the part anywhere, calling it a control arm. It’s some sort of suspension link for the upper control arm I believe. With typing in control arm and calling around parts shops, they all have the same answer: control arm. I hope this helps... It’s not the name but the part looks the exact same as the lateral link, so maybe the name is another suspension link? I do not know, but I will be physically going to the parts store today for a print out with the parts labeled if possible. Like I mentioned, the parts look the exact same. One might latch on different, but looking at the video it looks the same to me. I cannot figure it out without the labeled parts. Thank you for your help.

Hi! It’s the lower arm, thank you. I’ve contacted my parts store and they have it in stock. Thanks for the labeled image!
