The coil spring suspension replacement of a Steering Knuckle requires first lifting and supporting the vehicle and then removing the tire followed by the wheel. A suitable jack should be used to support the lower
Control Arm during Wheel Hub and bearing removal. First disconnect the electronic suspension control (ESC) link rod from its sensor before detaching the outer tie rod from the knuckle. First remove the brake hose bracket retaining bolt from the knuckle and then use j 43631
Ball Joint remover with j 45851 Ball Joint separator protector adapters to remove the upper retaining nut which isolates the upper Ball Joint from the Steering Knuckle followed by removing the lower Ball Joint. The mechanic should remove the Steering Knuckle followed by a cleaning step which removes contaminants from the upper and lower ball joints as well as the Tie Rod End while checking the tapered areas of the knuckle. Steering knuckles must be replaced when tapered holes show signs of elongation or out-of-roundness or damage. Lay the Steering Knuckle into position then attach the lower Ball Joint next and finish with the retaining nut tightened to 100 nm (74 ft. Lbs.). The upper Ball Joint requires installation on the Steering Knuckle before implementing its retaining nut which should get tightened to 50 nm (37 ft. Lbs.). The brake hose bracket retaining bolt fits onto the knuckle and receives a torque of 9 nm (80 inch lbs.). Now secure the outer tie rod into position on the Steering Knuckle and the Wheel Hub and bearing assembly. Attach esc link rod to sensor before installing tire and wheel and removing vehicle stands before lowering the car.
