Jeep 4877659AD Knuckle

If you're working on a 4WD model, remove the driveaxle/hub nut. Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands before removing the wheel. Remove the brake disc and wheel speed sensor, and if equipped with 4WD, take out the axle shaft nut. Next, remove the three hub bearing mounting bolts and take off the hub/bearing. Remove the outer tie-rod end retaining nut and separate the outer tie-rod end from the steering knuckle. Loosen the nut on the lower balljoint stud without removing it, then disconnect the balljoint from the steering knuckle using a balljoint removal tool; if you lack this tool, a picklefork type separator can be used, but it may damage the balljoint boot. Repeat this for the upper balljoint stud and then remove the knuckle. Carefully inspect the steering knuckle for cracks, particularly around the steering arm and spindle mounting area, and check the balljoint stud holes for elongation or cracks; if any issues are found, replace the steering knuckle. Installation is the reverse of removal, ensuring all suspension fasteners are tightened to the specified torque.
