So im looking to buy a new rear control arm bushing i have been looking at rockauto.com for the part but im not sure what one i need! can someone help me locate the right part for a 2003 svt focus thanks

If it is the part I am thinking of it is not replaceable, you need to get a new control arm. At least on my rear control arms there is a groove that holds the bushings that makes pressing them in and out not feasible. I ordered MEVOTECH MS40153 Control Arm. Do you have a picture of which bushing you want to replace?
