Use care when removing the halfshaft. When either end of the shaft is disconnected, overextension of the joint could result in separation of internal components and possible joint failure.

  1. Disconnect the negative battery cable.
  2.  
  3. Raise and safely support the vehicle. Remove the tire and wheel assembly.
  4.  
  5. If necessary, loosen or remove the stabilizer shaft link.
  6.  

Make sure to use the proper tools when separating the ball joint. Failure to use the proper tools can damage the ball joint and seal.

  1. Remove the lower ball joint cotter pin and nut, then loosen the joint using a suitable ball joint separator tool. If removing the right halfshaft, turn the wheel to the left, if removing the left halfshaft turn the wheel to the right.
  2.  
  3. Place a prybar between the suspension support and lower control arm, then separate the joint.
  4.  
  5. Insert drift into rotor and caliper to prevent rotor from turning, then remove the hub nut and washer using a hub nut socket tool.
  6.  
  7. Separate the axle from the hub using a suitable puller; the hub nut can be partially installed to protect the threads. Move the strut and knuckle rearward.
  8.

  1. Remove the inner joint from the transaxle using a suitable slide hammer and axle shaft remover tool.
  2.  

If equipped with the anti-lock brake system, care must be taken to prevent damage to the toothed sensor ring on the halfshaft and the wheel speed sensor on the steering knuckle.

To install:

  1. If installing the right side halfshaft, install a suitable axle seal protector, tool J 37292-A or equivalent. Install the tool in a position so it can be pulled out after the halfshaft is installed (T-handle between 5 and 7 o'clock position).
  2.  
  3. Seat the halfshaft into the transaxle by placing a suitable screwdriver into the groove on the joint housing and tapping until seated. Make sure the halfshaft is seated into the transaxle by grasping the housing and pulling outboard. Do not pull on the halfshaft.
  4.  
  5. Install the halfshaft into the hub and bearing assembly. Install a new hub nut. Insert a drift into the caliper and rotor to prevent the rotor from turning. Tighten the hub nut to 107 ft. lbs. (145 Nm).
  6.  
  7. Install the lower ball joint to the knuckle, and tighten the ball joint nut as follows:
    1. Step 1: Tighten the nut to 88 inch lbs. (10 Nm).
    2.  
    3. Step 2: Tighten the nut an additional 120° (2 flats on the nut), during which a torque of 41 ft. lbs. (55 Nm) must be obtained.
    4.  

  8.  
  9. Install a new cotter pin. If necessary to align the slot into the nut, tighten the nut up to one more flat. Never loosen the nut to install the cotter pin!
  10.  
  11. Install the stabilizer shaft link assembly and tighten the nut to 13 ft. lbs. (17 Nm).
  12.  
  13. If a boot protector was installed, remove it by pulling in line with the handle.
  14.  
  15. Install the tire and wheel assembly, then carefully lower the vehicle. Tighten the lug nuts to 100 ft. lbs. (135 Nm).
  16.

WARNING
Use care when removing the halfshaft to prevent the inner CV-joint from becoming over-extended. Over-extension of the joint could result in separation of internal components and possible joint failure.

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2.  
  3. Install a boot protector on the outer CV-joint boot.
  4.  
  5. Remove or disconnect the following:

    Front wheel
     

  6.  
  7. Loosen the stabilizer shaft link assembly bolt (to accommodate ball joint separation).
  8.  
  9. Remove the ball joint cotter pin and nut. Loosen the joint.
    NOTE
    The grease fitting may have to be removed from the ball joint for tool access.

  10.  
  11. Separate the lower control arm from the joint.
  12.  
  13. Remove or disconnect the following:

    Hub nut
     
    Halfshaft from the hub
     

  14.  
  15. Move the strut and knuckle rearward.
  16.  
  17. Remove the halfshaft from the transaxle.
    WARNING
    If equipped with anti-lock brakes, care must be used to prevent damage to the toothed sensor ring on the halfshaft and the wheel speed sensor on the steering knuckle.

When removing the halfshaft for any reason, the transaxle sealing surface (the male/female shank of the halfshaft) should be inspected for corrosion. If corrosion is present, the surface should be cleaned with 320 grit cloth or equivalent. Transmission fluid can be used to clean off any remaining debris. The surface should be wiped dry and the halfshaft reinstalled free of any build-up.
