Service and repair of the lower Ball Joint requires using two specific tools: Ball Joint remover/installer set (J9519-E) plus Ball Joint separator (J23742). First put the vehicle on stands and then lift it to suitable height. Take off the wheel while sitting the floor jack beneath the lower
Control Arm to hold its position and shield staff from harm. Set the floor jack beneath the lower Control Arm and lift it to stabilise the Control Arm. Use a wire to suspend the brake caliper before taking out the front braking unit. You need to unlock both lower Ball Joint parts before using the j23742 Ball Joint separator to free the joint from its spot on the
Steering Knuckle. Use a screwdriver to move the lower Control Arm out of the splash shield as you lift the upper Control Arm with a pry bar and place a wooden block between the frame and upper Control Arm to block the knuckle assembly. Put the lower Ball Joint remover/installer set j9519-30 to work when disconnecting the lower Ball Joint from the lower Control Arm. Check the tapered opening in the Steering Knuckle for damage and debris before deciding to replace the part if needed. Press a new Ball Joint into the lower Control Arm until it reaches the lower part using j9519-30 set butts. Take out the wooden blocking tool from the knuckle assembly area. Put the Ball Joint stud into the Steering Knuckle followed by the nut and tighten it to 94 ft. Lbs. At 128 nm while lining up the slot with the hole. Push a new cotter pin through the nut slots to the Ball Joint hole before curving it to stop the nut from sliding loose. Place the grease fitting on the Ball Joint and lubricate it. After this put back the front brake caliper and tire wheel unit. Take the safety stands out and release the vehicle to test the front wheel alignment.
