How to replace the front steering knuckle on a 4WD on GMC Sierra 1500?

Start the steerable knuckle replacement by first lifting the 4wd vehicle before supporting it while removing the tire and wheel. The next step involves removing the Wheel Hub combined with the bearing assembly. Lift the lower Control Arm using a suitable jack while you disconnect the outer tie rod from the Steering Knuckle. Begin by removing the brake hose bracket retaining bolt from the Steering Knuckle followed by removing the upper Control Arm retaining nut. The Ball Joint separation process starts through joint removal operation using j 43631 Ball Joint remover (J 43631) and j 45851 Ball Joint separator protector adapters (J 45851) on the Steering Knuckle's upper Ball Joint. Unload the lower Control Arm retaining nut before using the same tools to break apart the lower Ball Joint. Follow Steering Knuckle removal by cleaning the tapered parts and threads of the upper Ball Joint, lower Ball Joint and Tie Rod End free from grease and contaminants. Steering Knuckle replacement is required when inspection reveals elongated, out-of-round or damaged mounting surfaces or taper holes. Attach the new Steering Knuckle followed by installing the lower Ball Joint then torque its retaining nut to 100 nm (74 ft. Lbs.). Fasten the upper Ball Joint retaining nut while maintaining a torque of 50 nm (37 ft. Lbs.). Reinstall the brake hose and its mounting bracket retaining bolt while tightening it to 9 nm (80 inch lbs.). Next, connect the outer tie rod to the Steering Knuckle. Install first the Wheel Hub and bearing assembly and then replace the tire and wheel. Depress the lower Control Arm support before lowering the vehicle to perform alignment checks.
