To change the Steering Knuckle, first, the vehicle is raised and supported. Drill the Wheel Bearing and the outer tie rod to knuckle nut hole. With the use of the universal steering linkage puller (J 24319-B), remove the tie rod from the Steering Knuckle. Next, you are to remove the lower Control Arm and the strut to Steering Knuckle nuts and bolts after which you remove the Steering Knuckle from the car. For installation, connect the Steering Knuckle to the strut assembly, and if needed, the abs harness bracket, tighten the bolts and nuts to 120 n.m (89 lb ft). Route the axle through the Steering Knuckle, then install the lower Control Arm and finally the outer tie rod to the Steering Knuckle and torque the nut to 20 n.m (15 lb ft) then turn it a further 180 degrees then check the achieved torque to 50 n.m (37 lb ft). Lastly install the Wheel Bearing, brake rotor, brake caliper, and front wheels and bring the vehicle down then take a road test to confirm alignment and correct any lead or pull guiding any necessary attention.

The replacement of a Steering Knuckle begins with vehicle lifting and proper stabilization. First, remove the Wheel Bearing followed by the outer tie rod to knuckle nut. The universal steering linkage puller (J 24319-B) functions to disconnect the tie rod from the Steering Knuckle. Start by uninstalling the bolts of both the lower Control Arm and the strut to Steering Knuckle assembly before removing the Steering Knuckle block from the car. During installation process install the Steering Knuckle on the strut assembly and the optional abs harness bracket while tightening all bolts and nuts to 120 nm (89 ft. Lbs.). First guide the axle through the Steering Knuckle and install both the lower Control Arm and outer tie rod to the Steering Knuckle before tightening the nut to 20 nm (15 ft. Lbs.). Finish by turning the nut an additional 180 degrees and verifying the torque requirement at 50 nm (37 ft. Lbs.). Install the Wheel Bearing and brake rotor and brake caliper along with the front wheels onto the vehicle before lowering it for a road test to check alignment and resolve any lead or pull symptoms.

The wheel bearing, brake rotor, brake caliper, and front wheels.

Remove the lower shock to knuckle bolt, the coil spring, the toe link, the upper control arm to knuckle bolt and nut, the trailing arm to knuckle bolts, and the stabilizer shaft link to knuckle bolt.

Install the trailing arm to knuckle bolts and tighten them to 180 N.m (133 lb ft).

Lower the vehicle and perform a vehicle wheel alignment.
