Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Raise and support vehicle.
  4.  
  5. Remove wheel and tire assembly.
  6.  
  7. Remove cotter pin, nut lock and spring washer from end of halfshaft stub shaft and hub nut.
  8.  
  9. With aid of a helper applying brakes to keep front hub from turning, remove hub nut.
  10.  
  11. Access and remove front brake rotor.
  12.  
  13. Disconnect vehicle wiring harness from wheel speed sensor connector.
  14.  
  15. Unclip wheel speed sensor connector and routing clip from frame rail outer reinforcement.
  16.  
  17. Remove screw fastening wheel speed sensor routing bracket to strut assembly.
  18.  
  19. Open routing clip at knuckle and remove wheel speed sensor cable.
  20.  
  21. Push in on end of halfshaft stub shaft, pushing its splines out of hub splines.
  22.  
  23. Remove nut attaching outer tie rod to steering knuckle by holding outer tie rod stud stationary while loosening and removing nut with a wrench.
  24.  
  25. Remove tie rod from steering knuckle using Remover, Special Tool C-3894-A.
  26.  
  27. Remove two bolts attaching strut clevis to steering knuckle.
  28.  
  29. Tip knuckle outward at top and remove halfshaft stub shaft from hub and bearing. Suspend driveshaft straight outward using a bungee cord or wire. Do not allow driveshaft to hang by inner joint.
  30.  
  31. Remove ball joint nut using a power impact wrench. Because tapered stud is held sufficiently in knuckle at this time, it is not necessary to hold stud stationary to remove nut.
  32.  
  33. Reinstall ball joint nut until top of nut is even with top of ball joint stud. This action will keep stud from distorting while stud is released from knuckle in following step.
    WARNING
    Do not remove ball joint stud from steering knuckle using a hammer. Damage to Aluminum knuckle, ball joint or control arm will result.


    NOTE
    Lubricate Remover, Special Tool C-4150A, screw-drive threads before use to ease use and promote tool longevity.

  34.  
  35. Place Remover, Special Tool C-4150A, over ball joint stud and nut as shown. Release ball joint stud from steering knuckle by tightening tool screw-drive. To ease remover installation and use, it may help to rotate knuckle around so inside of knuckle faces outward.
  36.  
  37. Remove tool and nut from top of ball joint stud.
  38.  
  39. Remove steering knuckle from vehicle.
  40.  
  41. If hub and bearing needs to be transferred, remove four bolts attaching hub and bearing to knuckle, then remove hub and bearing.
  42.  

To install:

  1. If hub and bearing needs to be installed in knuckle, place hub and bearing squarely into center hole of knuckle with wheel speed sensor positioned toward trailing end of knuckle. Align threaded mounting holes of hub and bearing with mounting holes in steering knuckle, then install four mounting bolts. Progressively tighten mounting bolts in a crisscross pattern. Tighten mounting bolts to 45 ft. lbs. (65 Nm).
    WARNING
    Before installing knuckle on ball joint stud, wipe ball joint stud and knuckle contact area free of any grease or debris, otherwise damage to knuckle can occur. Use a clean shop cloth with Mopar® Brake Parts Cleaner applied to it for proper cleaning. Do not spray stud directly.

  2.  
  3. Place knuckle on ball joint stud.
  4.  
  5. Install a NEW steering knuckle to ball joint stud nut. Tighten nut by holding ball joint stud with hex wrench while turning nut with a wrench. Using a crowfoot wrench on a torque wrench, tighten nut to 60 ft. lbs. (81 Nm). Then, tighten nut an additional 1 / 4 (90°) turn after that torque is met.
  6.  
  7. Slide halfshaft stub shaft into hub and bearing assembly.
    WARNING
    The steering knuckle to strut assembly attaching bolts are serrated and must not be turned during installation. Install nuts while holding bolts stationary in steering knuckle.


    NOTE
    If vehicle being serviced is equipped with eccentric cam strut attaching bolts, eccentric cam bolt must be installed in bottom (slotted) hole on strut clevis bracket.


    NOTE
    The strut clevis-to-steering knuckle bolts are installed differently on each side. Left hand side bolts are to be installed from vehicle rear to front. Right side bolts are to be installed from vehicle front to rear.

  8.  
  9. Align steering knuckle in clevis bracket of strut. Install strut clevis-to-steering knuckle attaching bolts. Install nuts on ends of bolts and tighten to 60 ft. lbs. (81 Nm). Then, tighten nuts an additional 1 / 4 (90°) turn after that torque is met.
    WARNING
    Before installing tie rod stud in knuckle steering arm, wipe stud and knuckle contact area free of any grease or debris, otherwise damage to knuckle can occur. Use a clean shop cloth with Mopar® Brake Parts Cleaner applied to it for proper cleaning. Do not spray stud directly.

  10.  
  11. Install outer tie rod stud into knuckle steering arm from bottom. Start nut onto tie rod stud. While holding stud stationary using a socket, tighten nut using a wrench. Using a crowfoot wrench on a torque wrench, tighten nut to 35 ft. lbs. (47 Nm). Then, tighten nut an additional 1 / 2 (180°) turn after that torque is met.
  12.  
  13. Place wheel speed sensor cable grommet in clip at knuckle. Close clip.
  14.  
  15. Attach wheel speed sensor routing bracket to strut assembly. Tighten screw to 115 inch lbs. (13 Nm).
  16.  
  17. Clip wheel speed sensor connector and routing clip to frame rail outer reinforcement.
  18.  
  19. Connect vehicle wiring harness to wheel speed sensor connector.
  20.  
  21. Install brake rotor, then install disc brake caliper and adapter assembly.
  22.  
  23. Verify that wheel speed sensor is not routed improperly allowing cable to come in contact with brake rotor or other moving parts.
  24.  
  25. Install washer and hub nut on end of halfshaft stub shaft. With aid of a helper applying brakes to keep front hub from turning, tighten hub nut to 180 ft. lbs. (244 Nm).
  26.  
  27. Install spring washer and hub nut lock over hub nut and stub shaft. Install a NEW cotter pin securing nut lock in place and tightly wrap cotter pin prongs around nut lock.
  28.  
  29. Install tire and wheel assembly. Tighten wheel mounting nuts to a torque of 100 ft. lbs. (135 Nm).
  30.  
  31. Lower vehicle.
  32.  
  33. Pump brake pedal several times to ensure vehicle has a firm brake pedal before moving vehicle.
  34.  
  35. Check and adjust brake fluid level as necessary.
  36.  
  37. Perform wheel alignment.
  38.
