The steering knuckle is a single casting with legs machined for attachment to the front strut assembly and lower control arm ball joint. It also has machined areas to support and align the caliper assembly. The knuckle also holds the front halfshaft out CV-Joint hub and bearing assembly. Be aware that a new replacement hub nut must be used for this service.

  1. Disconnect the negative battery cable.
  2.  
  3. Raise and support the vehicle safely.
  4.  
  5. Remove the front wheel(s).
  6.  
  7. Remove the front caliper assembly from the steering knuckle.
  8.  
  9. Remove the front brake rotor from the hub by pulling it straight off wheel mounting studs.
  10.  
  11. Remove the Anti-lock Brake System (ABS) speed sensor cable routing bracket from the strut assembly. Remove the screw attaching the speed sensor to the steering knuckle. If the sensor is seized, use a small hammer and a punch and gently tap the edge of the sensor ear, rocking the sensor side to side until it is free.
  12.  
  13. Remove the hub and bearing-to-stub axle retainer nut. This hub nut is a torque prevailing retaining nut and can not be reused. A NEW retaining nut MUST be used when assembling the hub to complete this repair.
  14.  
  15. Remove the three steering knuckle to hub assembly attaching bolts.
  16.  

If the metal seal on the hub and bearing assembly is seized to the steering knuckle and becomes dislodged on hub and bearing during removal, the hub and bearing must be replaced. If the flinger disc becomes damaged during the removal procedure, the hub and bearing assembly must be replaced.

  1. Remove the hub and bearing assembly from the steering knuckle by pulling it straight out of the knuckle and off the ends of the stub shaft. Due to rust and corrosion, especially on high-mileage vehicles, it will probably be necessary to gently pry the assembly out with a prybar or tap it out with a soft face hammer. Be careful not to damage the hub and bearing assembly, if it is to be reused. Once loosened, remove the hub and bearing assembly from the steering knuckle by sliding it straight out of the knuckle and off the ends of the stub shaft.
  2.  
  3. To remove the steering knuckle, remove the ball joint stud-to-steering knuckle clamp nut and bolt. Do not allow the ball joint seal to hit against the steering knuckle when the lower arm is separated from the steering knuckle.
  4.  
  5. Carefully insert a prybar between the lower control arm and the steering knuckle. Push down on the prybar to separate the ball joint stud from the steering knuckle. Take care not to cut the ball joint seal during disassembly.
  6.  
  7. Remove the strut assembly to steering knuckle nuts from the bolts.
  8.  


WARNING
The steering knuckle bolts are serrated (toothed) where they go through the strut assembly and steering knuckle. Do not turn the bolts during removal or damage to the knuckle will result.

  1. Remove the steering knuckle from the vehicle.
  2.  

To install:
  1. Clean and inspect all parts well. Check the seal boots on the lower ball joint and steering tie rod end. Begin reassembly by installing the steering knuckle onto the ball joint stud and tighten bolt to 40 ft. lbs. (55 Nm).
  2.  
  3. Position the steering knuckle neck into the strut assembly and align the bolt holes.
  4.  
  5. Install the strut assembly to steering knuckle retaining bolts and while holding the bolt heads stationary with a wrench, tighten nuts to 125 ft. lbs. (169 Nm). Use a wrench to hold the nuts while turning the bolts. Do not allow the bolts to turn in the steering knuckle or damage to the knuckle will result.
  6.  
  7. Clean the hub and bearing mounting surfaces of dirt and make sure there are no nicks present. Install the hub and bearing to the stub shaft and the steering knuckle. Install the 3 bearing assembly mounting bolts and tighten equally until the bearing assembly is seated squarely against the front of the steering knuckle. At this point, tighten the three mounting bolts to 80 ft. lbs. (110 Nm).
  8.  
  9. Install a new hub and bearing assembly-to-stub shaft retainer nut. A NEW retaining nut MUST be used when assembling the hub. Tighten but do not torque the nut at this time.
  10.  
  11. Install the speed sensor cable routing bracket and secure attaching screw. Coat the head of the speed sensor with a thin coat of high temperature multi-purpose grease and install it into the steering knuckle. Tighten he retaining screw to 60 inch lbs. (7 Nm).
  12.  
  13. Inspect the brake rotor and front disc brake pads and service or replace these items as required. Install the brake rotor and the caliper assembly. Install the caliper to steering knuckle retainer bolts and tighten to 14 ft. lbs. (19 Nm)
  14.  
  15. Install the front wheel(s) and lug nuts. Tighten the lug nuts, in a star pattern sequence, to 95-100 ft. lbs. (129-135 Nm). Lower the vehicle to the ground. Pump the brakes until a firm pedal is obtained.
  16.  
  17. With the weight on the vehicle on its wheels, apply the brakes to keep the vehicle from moving. Tighten the hub and bearing assembly to stub shaft retaining nut to 120 ft. lbs. (163 Nm).
  18.  


WARNING
When tightening the hub and bearing assembly to stub shaft retaining nut, do not exceed the maximum torque of 120 ft. lbs. (163 Nm). If the maximum torque is exceeded this may result in a failure of the halfshaft.

  1. Connect the negative battery cable.
  2.  
  3. Inspect the toe setting on the vehicle and adjust, if necessary.
  4.  
  5. Road test vehicle to verify proper operation and no front wheel bearing noise.
  6.
