  Q: How to Remove and Install a Steering Knuckle on Chrysler Concorde?

  A:

  To pull the steering knuckle out, ensure the car is elevated, remove the front wheel and tire assembly and then simply work the knuckle loose from its connectors. Take apart the caliper from the knuckle at the front of the vehicle and remove the rotor from the hub. Remove the wheel speed sensor from the steering knuckle because the outer C/V joint can become damaged when you pull out the hub and bearings; if the sensor is unable to move, use a hammer and punch instead of pliers. Remove the hub and bearing from the stub axle retaining nut and undo the three steering knuckle to hub and bearing assembly bolts. If you try to take out a seized metal seal during removal, you should replace the whole hub and bearing assembly. Pull the hub and bearing straight from the steering knuckle, but if it doesn't budge, carefully pry it open with a pry bar and tap the stub shaft with a soft face hammer. Unscrew the nut and bolt linking the ball joint stud to the steering knuckle to not damage the seal by having it brush against the knuckle. Slide the pry bar gently in between the lower Control Arm and steering knuckle to take out the ball joint stud. As you take off the strut assembly bolts, simply slide off the nuts without rotating the bolts which prevents damage. Just after taking out the inner tie rod ends, fit the new steering knuckle onto the ball joint stud and fix it by screwing on the assembly bolt and nut. Tighten the bolt with the torque wrench, using a reading of 55 Nm (40 ft. lbs.). Install the steering knuckle into the strut assembly first, without rotating any bolts and use a torque wrench to fasten the strut clevis and steering knuckle attaching bolt nuts to 150 ft./lbs. Inspect the mounting surfaces on the assembly to verify they are free of anything and put the hub and bearing assembly onto the stub shaft until it's properly attended. Screw on the three steering knuckle to hub and bearing assembly bolts and tighten them to 80 ft. lbs. (110 Nm). Attach a replacement hub and bearing axle retaining nut onto the stub shaft, but don't tighten them just yet. Apply High Temperature Multipurpose E.P. Grease to the speed sensor head prior to inserting it into the knuckle, then tighten it in place with a screw set to 7 Nm (60 inch lbs.). After that, set the brake rotor back onto the hub and bearing assembly, then attach the front Brake Caliper and tighten the bolts to 22 Nm (192 inch lbs.). Press on the brakes and then tighten the axle nut till it reaches 142 Nm (105 ft. lbs.). After that, install the wheel and tire once more, making sure to tighten the mounting stud nuts as detailed in the steps provided and repeat those steps for the entire 135 Nm (100 lb. ft.) of screwhook torque before you place the car back on the ground.

  Q: How to Service a Steering Knuckle on Chrysler Concorde?

  A:

  Before working on the steering knuckle, lift the vehicle up on jackstands or a frame contact hoist and take off the front wheel and tire assembly. Remove the front caliper from the steering knuckle and free the front rotor from the hub. Remove the wheel speed sensor to protect the outer C/V joint when you remove the hub and if the sensor can't move, use a hammer and punch to unseize it, not pliers. After that, take off the hub and bearing retaining nut, along with the three bolts connecting the steering knuckle to the hub and bearing assembly. Should the seal between the hub and bearing assembly jam and it is dislodged while removing it, then it has to be changed, as must any damaged flinger disc. Remove the hub and bearing from their place inside the steering knuckle by gently sliding them out. If it is stuck, carefully pry it out and gently knock the stub shaft with a soft face hammer. Carefully remove both stud nut and bolt so the ball joint seal remains clear of the steering knuckle. With a pry bar, split the ball joint from the steering knuckle and ensure you do not turn the bolts in the steering knuckle as you remove them. Lastly, take out the steering knuckle from the vehicle. Installation should start by connecting the steering knuckle to the ball joint stud and attaching it with the bolt, tightened to a torque of 55 Nm (40 ft. lbs.). Line up the steering knuckle with the strut assembly, avoiding twisting the bolts as you put them in, then tighten the strut clevis to steering knuckle attaching bolt nuts up to 203 Nm (150 ft. lbs.). See that the mounting surfaces are clean and not damaged, then set the hub and bearing assembly onto the stub shaft until it stays in position. Secure the hub and the bearing assembly to the three bolts and use a new retaining nut to fasten them all to 110 Nm (80 ft. lbs.). Cover the speed sensor head with High Temperature Multipurpose E.P. Grease before fitting, install it by hand with a seven Newtons millimetre (six inch pound) torque, replace the front brake rotor and caliper and tighten the caliper bolts to twenty Newtons millimetre (one hundred ninety inch pounds) torque. Following the application of the brakes, tighten the axle retaining nut to 142 Nm (105 ft. lbs.), put the wheel and tire assembly back on and tighten the wheel mounting stud nuts to 135 Nm (100 ft. lbs.) in the correct sequence. When lifted, remove the lift from the vehicle.
