Knuckle

When replacing a Steering Knuckle begin by elevating and supporting the entire vehicle. The starting point consists of removing the brake caliper and rotor and detaching the stabilizer shaft link from the lower Control Arm together with disconnecting the Wheel Speed Sensor connector. Lift the lower Control Arm with a jackstand then extract the outer tie rod ball stud from the linking mechanism that attaches to the Steering Knuckle. The Steering Knuckle needs removal after using j-42188-b to separate both upper and lower ball joint studs from the knuckle. At the end of the process remove the Steering Knuckle from the vehicle. To begin installation you must attach the Steering Knuckle to both upper and lower control arms after you remove the jackstand. Place the steering linkage outer tie rod ball stud onto the Steering Knuckle while observing fastener caution requirements. Reattach the stabilizer shaft link to the lower Control Arm while fastening it to a torque of 72 nm (53 lb ft). After connecting the Wheel Speed Sensor electrical connector you must install the brake rotor along with the caliper. Put the tire on the wheel and lower the car before verifying and correcting front wheel toe alignment if needed.

The start of front Steering Knuckle replacement requires vehicle elevation and support. Disconnect the brake caliper and remove rotor before detaching the stabilizer shaft link from the lower Control Arm along with separating the Wheel Speed Sensor electrical connector. Support the lower Control Arm using a jackstand. Use the ball joint separator (J 42188) to detach the outer tie rod ball stud from the Steering Knuckle using this tool before working on the upper Control Arm ball joint stud and lower ball joint stud. The vehicle should have its Steering Knuckle removed after the separation process completes. Begin installation by connecting the Steering Knuckle to both the upper and lower control arms followed by dismounting the jackstand. Connect the steering linkage outer tie rod ball stud to its position on the Steering Knuckle then install the stabilizer shaft link onto the lower Control Arm before torquing the stabilizer shaft link nut to 72 nm (53 ft. Lbs.). The Wheel Speed Sensor electrical connector needs to be connected first followed by installation of the brake rotor and caliper as well as the tire and wheel assembly before the vehicle can be lowered to check the required front wheel toe alignment.

Remove the suspension knuckle itself.

Reconnect the steering linkage outer tie rod ball stud to the steering knuckle, followed by the stabilizer shaft link to the lower control arm.

Remove the brake caliper and rotor, then detach the stabilizer shaft link from the lower control arm and disconnect the wheel speed sensor electrical connector.

Install the spindle nut, washer, and retainer, followed by the outer tie rod end.

Separate the suspension knuckle from the upper control arm and the lower control arm ball joint stud.

Remove the brake caliper and rotor, then detach the stabilizer shaft link from the lower control arm and disconnect the wheel speed sensor electrical connector.

Support the lower control arm using a jackstand.

Remove the jackstand and install the steering linkage outer tie rod ball stud to the steering knuckle.

Remove the brake caliper and rotor, then detach the stabilizer shaft link from the lower control arm and disconnect the wheel speed sensor electrical connector.
