Removal & Installation




CAUTION
To prevent personal injury and/or component damage, do not allow the weight of the vehicle to load the front wheels, or attempt to operate the vehicle, when the halfshaft(s) or halfshaft nut(s) are removed. To do so may cause the inner bearing race to separate, resulting in damage to brake and suspension components and loss of vehicle control.


WARNING
Wheel drive shaft boots, seals and clamps should be protected from sharp objects any time service is performed on or near the halfshaft(s). Damage to the boot(s), the seal(s) or the clamp(s) may cause lubricant to leak from the joint and lead to increased noise and possible failure of the halfshaft.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Raise and suitably support the vehicle.
  4.  
  5. Remove the wheel and the tire.
  6.  
  7. Remove the control link.
  8.  
  9. Remove the front halfshaft nut. Insert a drift or a flat-bladed tool into the caliper and the rotor to prevent the rotor from turning.
  10.  
  11. Disconnect the outer tie rod assembly from the steering knuckle.
  12.  
  13. Separate the ball joint from the steering knuckle.
  14.  
  15. Separate the front halfshaft from the front halfshaft bearing using a slidehammer and adapter.

To install

  1. Install the front wheel drive axle into the transaxle.
  2.  
  3. Verify that the front halfshaft retaining ring is properly seated:

    Grasp the inner housing and pull the inner housing outward. Do not pull on the front wheel drive axle shaft.
     
    The front wheel drive axle will remain in place when the front halfshaft retaining ring is properly seated.
     

  4.  
  5. Install the front wheel drive axle into the front halfshaft bearing.
  6.  
  7. Connect the ball joint to the steering knuckle.
  8.  
  9. Connect the outer tie rod assembly to the steering knuckle.
  10.  
  11. Install a new front halfshaft nut. Insert a drift or a flat-bladed tool into the caliper and the rotor to prevent the rotor from turning. Tighten the nut to 118 ft. lbs. (160 Nm).
  12.  
  13. Install the control link.
  14.  
  15. Install the wheel and the tire.
  16.  
  17. Lower the vehicle.
