The xAxis Sealed Flex Joint is a straight replacement for the cross axis balljoint found in the rear lateral link on the Dodge Caliber, Jeep Compass, and Patriot. Use press 29507 and balljoint press #72509 or 40920 to press out the original cross xaxis balljoint and press in the xAxis. The same xAxis is used in SPC # 67455 if you want a remove and replace arm that offers camber adjustment. California Residents WARNING
