So I ran the search but I found no results for what I'm about to ask. <p>My car, unfortunately, suffers from rear side hop. It's quite annoying on the highway going over bumps and stuff - makes you think the rear is getting away from you for a second. <br>I've read that to fix this issue some have replaced the "rear bushings" <br>What are those "rear bushings" and where do I get them from? Upgraded ones perhaps?<br>Is this something that could be fixed under warranty?
