What is this called?

I was having some issues with the front left tire where I could hear a terrible squeaking noise. At first I thought it was the wheel bearings going out on it, but after noticing that this part was rather loose (and when applied pressure and turned), it made a very similar noise to that of what I heard while driving. I looked on the other side and see that the part can't be turned on that side, so I know something isn't quite right here.

This is on a 2001 Chevy Blazer

Any help is appreciated. Thanks.

sway bar end links

Thanks :)

When replacing make sure you have a good pry bar and a buddy to make it easier I found mine harder to do but I didn't loosen up the sway bar any

Probably a good idea to get the whole link and not just bushings. They usually break the bolt, and the washers deformed.

Yeah get the kit they're fairly inexpensive and replace both at once one of mine was missing I'll be the first to tell you it's like being on a boat on pavement
