GM 19303856
Knuckle, Passenger Side

Before beginning the Steering Knuckle replacement process start by raising and supporting the vehicle while removing the tire and wheel assembly. Remove the wheel bearing/hub assembly from the complete vehicle. Through the use of a universal steering linkage puller (J 24319-B) you should separate the outer tie rod from the Steering Knuckle after removing the outer Tie Rod End retaining nut. Look for and take off the lower Ball Joint cotter pin and retaining nut before you separate the lower Ball Joint from the Steering Knuckle using the Ball Joint separator (J 43828). Next, take out the Steering Knuckle by removing its front strut to Steering Knuckle retaining bolts and nuts. The lower Ball Joint installation requires stepping by to the Steering Knuckle and applying the lower Ball Joint retaining nut before tightening it to 10 nm (89 inch lbs.) additional 180 degrees while maintaining cotter pin alignment across two slots. Heavy torque the outer Tie Rod End nut to 30 nm (22 ft. Lbs.) plus an additional 180 degrees before attaching the Steering Knuckle to its mounting bolts and nuts which need to be torqued to 147 nm (108 ft. Lbs.). Assembly begins with the Steering Knuckle/drive axle mounting of the hub and bearing before adding the brake rotor. Use a drift or screwdriver to stop the rotor from rotating before securing the drive axle nut up to 160 nm (118 ft. Lbs.). Last, install the tire and wheel while aligning the vehicle.

The Steering Knuckle replacement process starts by lifting and securing the vehicle followed by tire wheel removal then braking rotor removal and front Wheel Bearing and hub disassembly. Use the steering linkage and tie rod puller (J24319-B) to detach the tie rod from the Steering Knuckle. First remove the outer tie rod to the Steering Knuckle retaining nut. Start by taking out the retaining nut and cotter pin on the lower Ball Joint. Then use the Ball Joint separator (J43828) to separate the lower Ball Joint from the Steering Knuckle. You must unfasten all strut to Steering Knuckle mounting fasteners to extract the Steering Knuckle. Start by placing the Steering Knuckle to the strut end lower Ball Joint following the fastener notice in service precautions. Secure the strut onto the Steering Knuckle's mounting bolts while torquing them to 185 nm (136 ft. Lbs.). The installation of the lower Ball Joint retaining nut requires no backing off for proper cotter pin positioning. When attaching the outer tie rod to the steering column knuckle the lower Ball Joint retaining nut must reach 10 nm (88 inch lbs.) after adding an additional 180-300 degrees (3-5 flats) so that cotter pin alignment never exceeds 60 degrees. Secure the outer tie rod retaining nut by while torquing it to 47 nm (35 ft. Lbs.). Reinstall the Wheel Bearing followed by hub and brake rotor along with tire and wheel before performing a wheel alignment check.

Use the Steering Linkage and Tie Rod Puller (J 24319-B).

Position the new steering knuckle and install the lower ball joint into it.

Remove the lower ball joint cotter pin and retaining nut, then use the Universal Steering Linkage Puller (J24319-B) to separate the lower ball joint from the steering knuckle.

Tighten it to 10 Nm (88 inch lbs.) plus an additional 180 degrees - 300 degrees (3 - 5 flats), and then insert a new cotter pin.

Tighten to 95 Nm (70 ft. lbs.).

Install the lower ball joint retaining nut and tighten it to 10 Nm (88 inch lbs.) plus an additional 150 degrees, ensuring cotter pin alignment without backing off the nut.

Remove the wheel bearing and hub.

Utilize the Steering Linkage and Tie Rod Puller (J 24319-B).

Raise and support the vehicle.
