Ball Joint, Front Lower

Begin the lower Control Arm replacement process by taking out the assembly first. Place the lower Control Arm in the vise for safely holding it during installation. Begin drilling with the help of a center punch when working with a drill on rivets before removing the rivet head by drilling or grinding. Strike the lower Control Arm rivets with a punch and hammer until they let go from their position. Take out the Ball Joint from the lower Control Arm after this step. Install the Ball Joint onto the lower Control Arm while keeping the bolt in place and apply the appropriate torque during nut tightening. Secure the Ball Joint mounting parts after inserting bolts then tighten the nuts to 68 nm (50 lb ft). Sleep the Control Arm unit out of the vise and put it back into position. End your process by examining how straight the vehicle's front section is positioned.

When changing the Ball Joint of the lower Control Arm you must first remove the complete assembly. Secure the lower Control Arm inside a vise for further work. Start the drill using a center punch before drilling or grinding off the rivet's head. You should use a punch with hammer to detach the lower Control Arm rivets prior to separating them from the assembly. Proceed by removing the Ball Joint from your lower Control Arm assembly. During installation keep holding the bolt while tightening the nut to achieve the correct torque value when setting the Ball Joint onto the lower Control Arm. After positioning the Ball Joint mounting hardware secure its nuts and bolts until they reach 68 nm (50 lb ft) scale. When you finish working with the vise remove the complete lower Control Arm assembly then reinstall the entire lower Control Arm unit. All vehicle front end alignments must be checked during this stage of the project.
