Start your Steering Knuckle replacement work on a 4wd vehicle by first raising the vehicle and applying support before removing both the tire and wheel. Rotate the
Torsion Bars while removing the wheel drive shaft before finally taking out the Wheel Hub and bearing. First remove the outer tie rod to Steering Knuckle retaining nut then disconnect the outer tie rod from the Steering Knuckle by using the steering linkage and tie rod puller (J 24319-B). The first step requires removal of the brake hose bracket retaining bolt on the Steering Knuckle before extracting the upper
Ball Joint retaining nut to separate the upper Ball Joint from the Steering Knuckle using the Ball Joint remover (J 43631) and Ball Joint separator protector adapters (J 45851). Use this same procedure to disconnect the lower Ball Joint which attaches to the Steering Knuckle by removing the lower
Control Arm retaining nut. Thoroughly wipe the tapered section along with threads from the upper Ball Joint, lower Ball Joint, and tie rod end once you remove the Steering Knuckle before inspecting the knuckle's taper holes and mounting surfaces for deterioration. Embed the new Steering Knuckle into position then tighten the lower Ball Joint retaining nut to 100 nm (74 ft. Lbs.) and the upper Ball Joint retaining nut to 50 nm (37 ft. Lbs.). Both the brake hose bracket and outer tie rod should be installed onto their corresponding positions on the Steering Knuckle. Tighten the Steering Knuckle retaining bolt to 10 nm (88 inch lbs.) and secure the outer tie rod with a nut torque of 63 nm (47 inch lbs.). The Wheel Hub and bearing installation starts first followed by the wheel drive shaft and tire and wheel components. Torsion bars must be loaded next and the vehicle needs to be lowered before an alignment is performed.
