How to replace the lower ball joint on Buick Century?

Start by removing the lower Control Arm and securing it in the vice before starting the job. Use a tool to cut the ball stud rivets and then hit them out with a drift punch and hammer to dismantle the ball stud from the lower Control Arm. Place the ball stud on the Control Arm then insert the bolts starting with the new ball studs which point downward away from the stud. Secure the new ball stud nuts afterward. The fastener functions as a prevailing torque type but you can reuse it when both parts are rust-free and clean plus the fastener generates 2 n.m (18 lb in) of torque before fixing in place. New fasteners need replacement when these conditions are not met. Insert the lower Control Arm while tightening new ball stud nuts to 68 n.m (50 lb ft) settings.
