• Q: How to Maintain and Fix a Steering Knuckle on 2006 Jeep Commander?

  A: To work on and service the steering knuckle, raise and support the vehicle and then take off the tire and wheel assembly. Support the caliper so that it doesn't lean on the hose, then remove the caliper and its adapter without danger to the hose (1). Throw out the O-ring and pull off the disc brake rotor. After that, loosen the bolt at the wheel speed sensor (2) and remove the wires from the retaining clips on the knuckle. If your machine has four-wheel drive, remove the nut from the axle shaft and then take off the hub/bearing (3). Take off the outer tie rod end retaining nut and detach the outer tie rod end (3) from the steering knuckle using special tool 8677(5). Take the lower ball joint nut off and cut the ball joint using wheel C-4150A, so it separates from the knuckle (1). Separate the upper ball joint from the knuckle by removing its nut and using tool 8677. The last step is to take out the knuckle (3) from within the vehicle. For installation, set the knuckle (1) onto the vehicle, place the lower ball joint into the knuckle and tighten it with the lower ball joint nut to 95 Nm (70 ft. lbs.). Insert the upper ball joint into the knuckle, screw on the upper ball joint nut and tighten it securely using 95 Nm (70 ft. lbs.). Connect the tie rod end to the steering knuckle and toss on the hub/bearing (3), finalizing with a tightness of 115 Nm (85 ft. lbs.). Should the vehicle have four-wheel drive, put on the axle shaft nut and tighten it to 135 Nm (96 ft. lbs.). Reapply the wheel speed sensor (2), hook up the wire to the knuckle, then attach the disc brake rotor (1) and caliper adapter (1). After that, reinstall the wheel and tire and have the wheel alignment done once more.
