• Q: How to Remove and Install a Steering Knuckle on 2006 Chrysler Pacifica?

  A: First, lift and stabilize the car and once lifted, remove the tire and wheel. Now, remove the cotter pin, nut lock and spring washer from the halfshaft stub shaft and hub nut at that end. Applying brakes with the driver's side front being lifted, remove the hub nut by the helper. After that, access and remove the front brake rotor, cut the vehicle wiring harness from the wheel speed sensor connector and remove the connector and clip from the frame rail outer reinforcement. Detach the bracket screw at the strut assembly, unlock the bracket at the knuckle and pull the sensor cable out. Push towards the hub on the end of the halfshaft stub shaft to get the splines apart. After supporting the outer tie rod stud, remove the nut attaching the tie rod to your steering knuckle. Then, use Remover, Special Tool C-3894-A to separate the tie rod from the steering knuckle. Take out the bolts that join the strut clevis to the steering knuckle, tilt the knuckle up at the top to slide it off, detach the halfshaft stub shaft from the hub and bearing and suspend the driveshaft facing straight up. Replace the ball joint nut onto the stud with the power impact wrench and move the nut up until it is identical with the top of the nut so nothing is distorted. With Remover, Special Tool C-4150A, separate the ball joint stud from the steering knuckle and then pull out the steering knuckle from the vehicle. Should you need to move the hub and bearing, undo the four bolts that secure them to the knuckle. If you find any cracks, dents or stress marks where the knuckle meets the housing, the part must be changed immediately. If using the hub and bearing in the knuckle, start by placing the hub and bearing on axis, then position the wheel speed sensor towards the end of the knuckle with the hub, add the threads and fasten them with four bolts torqued to 65 Nm (45 ft. lbs.) in a line across the hub. Before putting the knuckle onto the ball joint stud, make sure to clean the area contact. Cover the end of the stud with a knuckle, fit the ball joint stud nut to a new steering knuckle and use a crowfoot wrench to tighten it to 81 Nm (60 ft.-lbs.). Add another 1/4 turn afterward. Slide the halfshaft stub shaft into the hub and bearing assembly so that the attaching bolts of the steering knuckle to strut assembly remain in position. If your strut has eccentric cam strut attaching bolts, insert the eccentric cam bolt into the bottom hole of the strut clevis bracket. Set the steering knuckle into the strut's clevis bracket, insert the bolts, tighten them up and turn them an additional 1/4 turn. You should clean the tie rod stud's place of contact and the knuckle bearing arm before putting the outer tie rod stud into the steering arm, putting the nut on the stud and tightening it to 47 Nm (35 ft. lbs.) by an extra 1/2 turn. Put the wheel speed sensor cable grommet into the clip at the knuckle and snap the clip closed, then attach the routing bracket to the strut and tighten the screw to 13 Nm (115 inch lbs.). Fasten the connector and support clip of the wheel speed sensor to the outer part of the frame rail reinforcement, connect the car wiring to the wheel speed sensor and position the brake rotor, disc brake caliper and adapter assembly after that. Be sure that the wheel speed sensor cable is not touching any moving part and especially the brake rotor. Mount the washer and hub nut on the stud at the end of the halfshaft stub shaft, then use a helping hand to press the brakes as you tighten the hub nut to 244 Nm (180 ft. lbs.). Put the spring washer and the hub nut lock over the hub nut and stub shaft, hold them in place using a new cotter pin. After that, install the tire and wheel combo, make sure the wheel mounting nuts are secure at 135 Nm (100 ft. lbs.), lower the vehicle to the ground, press the brake pedal a few times, review the brake fluid level and do a wheel alignment.
