To remove the control arm first undo the wheel lugs but do not take the nuts off completely, then find a comfortable working position on the side of the vehicle and and lift the rear of the vehicle using the jack and place it on the jackstands. Next to do is strip off the tire and wheel assembly, after that, take off the cotter pin along with the nut from the balljoint stud. To remove the lower arm abut from the ball joint, employ the two-jaw puller, then after doing this, take out the strut rod nut and its retainer from the lower arm. Next to do this, loosen the pivot bolt securing the lower arm to the body of the car and then pull on the lower arm to take it off. To install the assembly, initially, fix the strut rod to the lower arm and the lower arm to the body with the nuts and bolts which are then tightened to the recommended torque value and new cotter pin installed at the lower arm to the ball joint nut. Tighten the strut rod to the lower arm and tighten the arm to the body to the torque indicated, then fit the tire and wheel and using a jerk tighten the nuts loosely before using the spring jack lowering the vehicle and tightening the nuts. On the actual assembly of the suspension, it is recommended to align the wheels afterwards. Regarding balljoint removal and installation, when the control arm has been removed, the two bolts fastening the balljoint to the carrier of the rear axle must be undone in order to disconnect the balljoint and the carrier. When fitting the balljoint to the car, the procedure is the reverse, but for these nuts tighten them till you get the right torque recommended.
