  1. With the vehicle on the ground, depress the brake pedal and loosen the drive axle-to-hub nut.
  2. Caution: Ensure that the vehicle is properly supported and squarely positioned. To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which the components are being removed.

  3. Raise the vehicle on a hoist.
  4. Remove the road wheel corresponding to the drive axle being removed.
  5. Remove the side splash shield corresponding to the drive axle being removed.

  6. Object Number: 877532  Size: SH
    4.1. Remove the 2 push pins.
    4.2. Remove the lower shield to cradle molded-in fasteners at the cradle by gently prying at the 3 fastener locations.

    Important: For the left side, remove the front section of the shield first, then the rear. For the right side, remove the rear section of the shield first, then the front

    Important: If molded-in fasteners are damaged or broken, drill out with a 8 mm (5/16 in) bit and replace with a push pin.

  7. If the left drive axle or the intermediate axle shaft is to be removed, place an approved container under the transaxle, remove the drain plug, and drain the fluid.

  8. Object Number: 859514  Size: SH
  9. Remove the drive axle nut and washer and discard the nut.
  10. Remove and discard the lower control arm-to-steering knuckle cotter pin.

  12. Object Number: 871526  Size: SH

    Notice: On ABS equipped vehicles, the outer CV joint has a speed sensor ring. Using the incorrect tool or procedure to separate the control arm from the knuckle can damage the ring, resulting in a loss of ABS operation.

    Notice: Do not attempt to separate the joint using a wedge-type tool because seal may be damaged.

  13. Using the SA9132S , separate the lower control arm from the steering knuckle.

  14. Object Number: 859978  Size: SH
  15. Remove the torque prevailing nut and discard. A new nut will be required during re-assembly.

  16. Object Number: 859514  Size: SH

    Notice: Do not attempt to separate the joint using a wedge-type tool because seal may be damaged.

  17. Using the SA91100C , separate tie rod end from steering knuckle.
  18. Remove the lower control arm-to-steering knuckle castle nut.

  19. Object Number: 864782  Size: SH

    Notice: Be sure to use cloths where the pry bar contacts the front stabilizer shaft and cradle to avoid surface damage to these components.

  20. Position a long pry bar at the proper cradle and front stabilizer shaft locations.
  21. Notice: Be careful not to allow steering knuckle to contact the ball stud seal. Contact may cause the seal to rip, requiring control arm replacement.

    Important: Place a cloth over the ball stud boot, protecting it from damage caused by contact with the steering knuckle.

  22. Pull down on pry bar, separating the lower control arm ball stud from the steering knuckle. Pull the steering knuckle away from the ball stud.

  23. Object Number: 871530  Size: SH

    Notice: To prevent damage to CV Joint boots, be careful not to allow them to contact other parts during the removal/installation process. Also, never pull on the shaft assembly.

    Important: If difficulty is encountered in separating the axle from the hub, tap on the end of the drive axle, using a block of wood and a hammer. Do not hammer directly on the end of axle.

  24. While pulling the knuckle/strut assembly away from the vehicle, pull the outer end of the drive axle out of the wheel hub.

  25. Object Number: 861887  Size: SH
  26. Support or suspend the drive axle assembly.

  27. Object Number: 861890  Size: SH
  28. For the right side drive axle, remove the drive axle from the intermediate axle shaft by tapping the axle at the correct location with a hammer, using a block of wood between the hammer and the drive axle. Separate the drive axle from the intermediate shaft.

  29. Object Number: 864656  Size: SH

    Notice: When inserting pry bar between the transaxle and drive axle, be careful not to contact transaxle oil seal or axle shaft deflector ring. Damage can occur to transaxle oil seal or axle shaft deflector ring if contact is made, requiring seal or deflector ring replacement.

  30. For the left side drive axle only, remove the drive axle by inserting a large pry par into the correct location and prying the axle out of the transaxle.
  31. Remove the drive axle from the vehicle.
