Halfshaft

Print

The halfshaft assemblies used on these cars are flexible units consisting of an inner Tri-Pot joint and an outer Constant Velocity (CV) joint. The inner joint is completely flexible, capable of up and down, in and out movement. The outer joint is only capable of up and down movement.

NOISE DIAGNOSIS



  1. Clicking noise in turn: inspect for worn or damaged outer CV-joint and outer dust boots.
  2.  
  3. Clunk when accelerating from coast to drive: inspect for worn or damaged outer CV-joint.
  4.  
  5. Shudder or vibration during acceleration: inspect for excessive joint angle, excessive toe, incorrect trim height, worn or damaged outer CV-joint and sticking spider assembly.
  6.  
  7. Vibration at highway speeds: inspect for out of balance rear tires or wheels, out of round tires or wheels, worn outer CV-joint and binding or tight joint.
  8.  

REMOVAL & INSTALLATION



Use care when removing the halfshaft. Tri-pot joints can be damaged if the drive axle is over-extended. It is important to handle the halfshaft in a manner to prevent over-extending.

  1. Disconnect the negative battery cable.
  2.  
  3. Raise the car and support with jackstands. Remove the wheel and tire.
  4.  
  5. Remove the brake calipers, bracket assemblies and hang out of the way with wire.
  6.  
  7. Remove the brake rotors.
  8.  
  9. Remove the four hub/bearing retaining bolts and hub.
  10.  
  11. If equipped with ABS brakes, remove the ABS sensor mounting bolt and position the sensor out of the way.
  12.  
  13. Place a drain pan under the transaxle.
  14.  
  15. RIGHT: using an axle shaft removing tool J-33008 or equivalent, separate the halfshaft from the transaxle.
  16.  
  17. LEFT: using a suitable prybar, separate the halfshaft from the transaxle. Pry on the frame and the groove provided on the inner joint.
  18.  
  19. Separate the halfshaft from the bearing assembly, if not removed.
  20.  

To install:
  1. Install the halfshaft/bearing assembly through the knuckle and into the transaxle until the retaining clip engages. Do NOT overextend the inner joint.
  2.  
  3. Install the ABS sensor.
  4.  
  5. Tighten the bearing assembly retaining bolts to 52 ft. lbs. (70 Nm).
  6.  
  7. Remove the drain pan and install a new halfshaft nut and washer.
  8.  
  9. Install the rotor, brake caliper and wheels.
  10.  
  11. Lower the vehicle and tighten the halfshaft axle nut to 184 ft. lbs. (250 Nm).
  12.  
  13. Add the necessary amount of transaxle fluid. Refer to Routine Maintenance of this repair guide.
  14.  
  15. Connect the negative battery cable.

Outer Joint Boot
  1. Cut and remove the boot retaining clamps with wire cutters.
  2.  
  3. Remove the race retaining ring with snapring pliers. Remove the joint and boot assembly from the axle shaft. Refer to Step 1 of the CV-joint procedures.
  4.  
  5. Flush the grease from the joint and repack the boot with half of the grease provided with the new boot.
  6.  
  7. Install the new boot and clamps first. Second, install the joint and snap the race retaining ring into place. Put the remainder of the grease into the joint.
  8.  
  9. Using an axle seal clamp tool J-35910 and a torque wrench, tighten the small clamp to 100 ft. lbs. (136 Nm). Tighten the large clamp to 130 ft. lbs. (176 Nm).
  10.  

Outer Joint Assembly
  1. Remove the large boot clamp and joint assembly from the axle as previously mentioned. Clean out the grease from the joint to aid in disassembly.
  2.  
  3. Use a brass drift to gently tap on the cage until tilted enough to remove the first ball. Remove the other balls in a similar manner.
  4.  
  5. Pivot the cage and inner race at 90 to the center line of the outer race with the cage windows aligned with the lands of the outer race. Lift the cage out with the inner race. Refer to Step 2 of the CV-joint procedures.
  6.  
  7. Rotate the inner race up and out of the cage as in Step 2. Clean all parts with solvent and blow dry with compressed air.
  8.  

To install:
  1. Lightly coat the ball grooves with the provided grease.
  2.  
  3. Install the inner race into the cage, cage into the outer race and balls into the cage as removed.
  4.  
  5. Refill the joint with half the grease provided. Install the boot and clamps. Install the joint onto the axle. Fill the joint with the remaining grease and tighten the clamps as in the outer joint boot procedure.
  6.  

Inner Tri-Pot Boot
  1. Cut the clamps from the boot.
  2.  
  3. Remove the spider assembly from the axle by removing the shaft retaining snaprings.
  4.  
  5. Clean all metal parts with solvent and blow dry with compressed air.
  6.  

To install:
  1. Refill the housing with half of the grease provided with the new boot. Install the boot and clamps first, then the spider and snapring assembly onto the axle.
  2.  
  3. Position the axle into the Tri-Pot housing. Install the remaining grease into the joint.
  4.  
  5. Using a seal clamp tool J-35910 or equivalent, tighten the small clamp to 100 ft. lbs. (136 Nm) and tighten the large clamp to 130 ft. lbs. (176 Nm). Side cutters can be used the tighten the boot clamps, but care must be used so not to cut the new clamps.
