Mopar 5168420AE Front Steering Knuckle

The bushing is present on the spring link which faces the rear knuckle; this bushing is covered by a metal sleeve which has to be pulled back before the spring link is disengaged from the knuckle and this needs specific tools. Unless the assembly is dropped at a dealer service department or to a qualified repair shop, both link and knuckle are again separable using some other tools and apart from this, a new metal sleeve is required for joining both of these. To be able to dismantle the spring link and the knuckle, the sub-frame has to be lowered one side at any one time and this requires using a good floor jack, jack stands and wooden blocks. To start with, free the wheel lug nuts, lift the rear of the car and then using the frame rails jack the car up and place it on supporting stands before nuts and bolts of the wheel are removed. Subsequently, disconnect the ABS wheel speed sensor, release the harness connected with the brake backing plate, thereafter, the hub and bearing assembly. Then, take off the rear parking brake shoes and disconnect the parking brake cable from the knuckle as well. Remove the fasteners of the spring link to subframe mounting and unbolt all the links connected to the knuckle apart from the spring link before taking out the knuckle gently. Installation is done in reverse of the removal and after tightening of all the spring link nut, it is recommended that the spring link should be lifted with the help of a floor jack and brought to normal height before tightening the toe link mounting fasteners to the recommended torque using a wood block and floor jack.

Loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands before removing the wheel. Next, take out the brake disc, wheel speed sensor, and the small bracket that holds the brake hose and ABS wheel speed sensor harness to the knuckle. Disconnect the tie-rod end from the steering knuckle, then separate the upper control arm, tension strut, and lower control arm from the steering knuckle. Carefully inspect the steering knuckle for cracks, particularly around the steering arm and spindle mounting area, as well as the balljoint stud holes; if any elongation or cracks are found, replace the steering knuckle. Balljoint removal will require special tools available at most auto parts stores, or the knuckle can be taken to a qualified repair facility for removal. Remove the hub or hub and bearing assembly, brake dust shield, or lower balljoint as necessary for replacement. Installation is the reverse of removal, ensuring that all suspension fasteners are tightened to the specified torque, followed by tightening the wheel lug nuts to the appropriate torque.
