    Q:
    How to replace the steering knuckle on a 4WD on Chevrolet Silverado 3500 Classic? Posted by Customer
    A:
    You should start by lifting the vehicle before supporting it when you want to replace a 4wd Steering Knuckle. Start by removing the wheel, then the tire followed by Wheel Hub alongside bearing assembly removal. A proper jack needs to stabilize the lower Control Arm before disconnecting the outer tie rod from the Steering Knuckle. The Steering Knuckle must yield the brake hose bracket retaining bolt. Use the Ball Joint separator (J-42188-B) to part the upper Ball Joint and Steering Knuckle after extracting the upper Control Arm retaining nut. Insulate the lower Ball Joint from the Steering Knuckle by first using the Ball Joint remover (J 43631) with Ball Joint separator protector adapters (J 45851). Stripping the Steering Knuckle requires cleaning the tapered areas and threads of all three components - the upper Ball Joint, lower Ball Joint, and tie rod end - from any remaining grease or contaminants. Examine the mounting surfaces as well as the taper holes on the Steering Knuckle. Replace the Steering Knuckle when it shows signs of elongated tapered holes or out of round or damaged condition. Insert the new Steering Knuckle then bolt the lower Ball Joint to its mounting position. Finally torque the retaining nut to 100 nm (74 ft. Lbs.). Install the upper Ball Joint to the Steering Knuckle followed by installing its retaining nut which needs to be tightened to 50 nm (37 ft. Lbs.). Screw in the brake hose and bracket retaining bolt onto the Steering Knuckle before tightening the bolt to 9 nm (80 inch lbs.). After connecting the outer tie rod with the Steering Knuckle you should install the Wheel Hub and bearing assembly before installing tire and wheel. After removing the lower Control Arm support, lower the vehicle before performing alignment.

    Q:
    How to replace the rear steering knuckle on Chevrolet Silverado 1500? Posted by Customer
    A:
    First, lift the vehicle to take off the tire and wheel, to change the rear Steering Knuckle. Next, take out the Wheel Hub and bearing, then the upper and the lower ball joints. Use the universal steering linkage puller having j 24319-b code, after unscrewing the outer tie rod retaining nut and bracket to disconnect the outer tie rod from the Steering Knuckle. Loosen the park brake cable retaining bolt from the Steering Knuckle and replace it with a new one. Get the Steering Knuckle and remove it from the vehicle. To fix, place the new Steering Knuckle on the vehicle, fix the ubi a and lower Ball Joint. Apply the retaining bolt of the park brake cable to the Steering Knuckle driving it to 65 nm (48 ft. Lbs.). Then, install the Wheel Hub and bearing, and the outer tie rod retaining nut, and tighten it to 55 nm (40 Ft. Lbs). Fasten the outer tie rod retaining bracket and tighten it to 65 nm (48 ft. Lbs.). Finally, you can re-install the tire and wheel, lower the car, and do a four-wheel alignment.

    Q:
    How to replace the steering knuckle in a torsion bar suspension system on GMC Yukon XL 2500? Posted by Customer
    A:
    Vehicles with torsion bar suspensions need a complete lift and support system before technicians can remove the tire and wheel. If your vehicle includes an electronic suspension control link rod you must disconnect this component from the sensor before supporting the Control Arm with a safety stand. When replacing a Steering Knuckle in a torsion bar setup start by unloading torsion bars before proceeding to remove the Wheel Hub bearing assembly and then the tie rod from the Steering Knuckle. Use the j 43631 (Ball Joint Remover) with j 45851 (Ball Joint Separator Protector Adapters) to separate the upper Ball Joint from the Steering Knuckle. Start by removing the upper Control Arm retaining nut then remove the brake hose bracket retaining bolt from the Steering Knuckle. The process to separate the lower Ball Joint from the Steering Knuckle uses the same tools to remove the retaining nut then install Ball Joint remover model j 43631 and separator protector adapters j 45851. Before reinstallation clean all threads and tapered areas of both ball joints and the Tie Rod End before inspecting the Steering Knuckle's tapered mounting surfaces. Replace the knuckle if you find elongated or damaged or misshaped holes. Thread the new Steering Knuckle onto the vehicle before installing the lower Ball Joint and securing its retaining nut with 100 nm (74 ft. Lbs.) torque. Fitting the retaining nut to the upper Ball Joint-aiming at 50 nm (37 ft. Lbs.) torque. Install the brake hose and the bracket retaining bolt to the Steering Knuckle before tightening the bolt to 9 nm (80 inch lbs.). Once that step is completed, add the outer tie rod to the Steering Knuckle and the Wheel Hub and bearing assembly. After connection of the esc link rod to the sensor (if equipped) you must install the tire and wheel along with loading torsion bars and removing safety stands before lowering the vehicle to perform wheel alignment verification steps.
