Installation of the halfshafts may require a special tool for the spline alignment of the halfshaft end and the transaxle case. Do not perform this procedure without access to this tool. The Kent Moore tool Number is J-34296 and J-34297

  1. Raise the front of the vehicle and support it on jackstands, then remove the wheel and the tire assembly.
  2.  
  3. Remove the cotter pin from the drive axle.
  4.  
  5. Have a helper firmly apply the brakes, and loosen the hub nut.
  6.  
  7. Remove the caliper assembly.
  8.  

It is not necessary to disconnect the brake hose from the caliper. Position the caliper out of the way and secure with mechanics wire.

  1. Using the removal tool HT72520000 or equivalent, remove the tie rod ball joint from the steering knuckle.
  2.  
  3. On 1982-86 vehicles, disconnect the ball joint from the lower control arm, by removing the mounting nuts from the bottom of the control arm.
  4.  
  5. On 1987-90 vehicles, disconnect the ball joint from the steering knuckle, using removal tool HT72520000 or equivalent.
  6.  
  7. Using a block of wood and a mallet, separate the halfshaft from the hub/steering knuckle assembly. If the assembly is difficult to separate it may be necessary to use a press/puller tool.
  8.  

In order to protect the halfshaft from damage, it is a good idea when striking the halfshaft, to temporarily install the hub nut.

  1. Drain the lubricant from the transaxle.
  2.  
  3. Support the engine properly and remove support bracket if so equipped.
  4.  
  5. Remove the halfshaft from the right side on automatic transaxle equipped vehicles and on all manual transaxles as follows:
    1. Insert a suitable prybar between the inner CV-joint and the transaxle.
    2.  
    3. Carefully pry the halfshaft from the transaxle.
    4.  

  6.  

When removing the driveshaft from the transaxle, do not pull on the driveshaft. The driveshaft will separate at the sliding joint (damaging the boot).

  1. Remove the left side halfshaft on automatic transaxles as follows:
    1. Remove the right side halfshaft as outlined above.
    2.  
    3. Insert a slotted screwdriver, from the right side of the transaxle.
    4.  

  2.  

Make certain that the screwdriver is properly aligned into the slot in the halfshaft.

  1. Tap the screwdriver with a mallet to remove the left side halfshaft from the transaxle.
  2.  

  1. Pull the hub/steering knuckle assembly away from the vehicle and remove the halfshaft from the transaxle.
  2.  

After removing the halfshaft from the transaxle, be sure to install a holding tool to hold the side gear in place while the axle is removed.

To install:
  1. Always use a new circlip on the driveshaft and install a new oil seal to the transaxle.
  2.  
  3. Install the halfshaft into the transaxle.
  4.  

When installing the driveshaft into the transaxle, use oil seal protector tool KV38105500 or equivalent to protect the oil seal from damage; after installation, remove the tool.

  1. Align the halfshaft with the hub/knuckle assembly and connect the lower control arm-to-ball joint.
  2.  
  3. On 1982-86 vehicles, connect the lower control arm to the ball joint and tighten the control arm-to-ball joint nuts to 40-47 ft. lbs. (54-64 Nm).
  4.  
  5. On 1987-90 vehicles, connect the lower ball joint to the steering knuckle and tighten the stud nut to 43-54 ft. lbs. (59-74 Nm).
  6.  
  7. Connect the tie rod to the steering knuckle and torque the tie rod stud nut to 22-36 ft. lbs. (30-49 Nm).
  8.  
  9. Install then hub nut and tighten to 87-145 ft. lbs. (118-197 Nm).
  10.  
  11. Install new cotter pin in drive axle and mount the caliper assembly.
