A vehicle support system and proper vehicle positioning are necessary before beginning the rear spring, insulator, and jounce bumper replacement. The first step begins by removing the wheel and tire from the rear position followed by placing an adjustable jack stand under the lower Control Arm. Begin by taking out the lower stabilizer shaft link bushing and nut then follow with removal of the lower shock absorber bolt and lower bolts from the knuckle. The adjustable jack stand will lower the vehicle to remove the rear spring , insulator and jounce bumper and spring seat . Position the spring seat together with the jounce bumper , rear spring and insulator onto the lower Control Arm during installation. Start by lifting the lower Control Arm with the adjustable jack stand before installing the lower bolts for the knuckle. Remove the stand afterward. First install the lower stabilizer shaft link bushing with its matched nut then add the lower shock absorber bolt. To complete the process install the rear tire and wheels then remove the support before lowering the vehicle.
