7 If the balljoint is worn it will be necessary to renew the arm complete as the balljoint cannot be removed separately.

Refitting
8 Refitting is the reverse sequence to removal. Tighten all nuts and bolts to the specified torque with the weight of the car on its roadwheels. When refitting the Torx pinchbolt, note that the head of the bolt must face the rear of the car.
