To install:


NOTE
Whenever the halfshafts are removed, the axle seals should be replaced.

  2.  
  3. Install or connect the following:

    Halfshaft into the transaxle, align the serration-s and remove the alignment tool
     

  4.  
  5. Push the halfshaft, then press-fit the circular clip on the shaft into the clip groove on the side gear.
    NOTE
    After insertion, attempt to pull the flange out of the side joint to be sure the circular clip is properly seated in the side gear and will not come out.

    Halfshaft from the knuckle by lightly tapping it with a hammer. If it is hard to remove, use a puller.
     

  6.  
  7. Remove the halfshaft from the transaxle as follows:
    1. Models without support bearing: Pry the halfshaft from the transaxle.
    2.  
    3. Models with support bearing: Remove the support bearing bolts and pull the halfshaft from transaxle.
      NOTE
      When removing the halfshaft from the transaxle, do not pull on the halfshaft. The halfshaft will separate at the sliding joint (damaging the boot). Use a small prybar to remove it from the transaxle. Be sure to replace the oil seal in the transaxle.

    4.  

  8.  
  9. Remove the halfshaft from the vehicle.
  10.  

To install:

  1. Use a new circlip on the halfshaft and install a new oil seal to the transaxle.
    NOTE

  2.  
  3. Install or connect the following:
    NOTE
    After installation of the halfshaft, try to pull the flange out by hand. If it pulls out, the circular clip is not locked into the transaxle.
