Fasten the front suspension crossmember front bolts and nuts to the lower Control Arm. Tighten them to 115 nm (84 ft. Lbs.) with 120 degrees of rotation added. Install the knuckle to the joint stud and fasten it using the nut. Torque it at a minimum of 55 nm or 41 ft. Lbs. And a maximum of 65 nm or 55 ft. Lbs. Then add the cotter pin.
