Halfshafts

Print

IDENTIFICATION



All LH platform vehicles are equipped with an unequal length driveshaft system. The left side of the vehicle is equipped with a longer driveshaft (also called a halfshaft) than the right side of the vehicle. The LH platform uses solid interconnecting shafts on both sides of the vehicles. The halfshaft assemblies are three piece units. Each halfshaft has a tripod joint, an interconnecting shaft and a outer CV-Joint. The tripod joint is splined onto the transaxle stub shaft and the outer CV-Joint has a stub shaft that is splined into the front wheel hub and bearing assembly.

WARNING
Allowing the CV-joint assemblies to dangle unsupported or pulling or pushing the ends can damage boots or CV-joints. Always support both ends of the halfshaft to prevent damage or disengagement of the Tripod joint.

  1. Disconnect the negative battery cable.
  2.  
  3. Raise and support the vehicle safely.
  4.  
  5. Remove the front wheels.
  6.  
  7. Remove the front caliper assembly from the steering knuckle.
  8.  
  9. Remove the front brake rotor from the hub by pulling it straight off wheel mounting studs.
  10.  
  11. Remove the speed sensor cable routing bracket from the strut assembly.
  12.  
  13. Remove the hub and bearing-to-stub axle retainer nut.
  14.  
  15. Install a puller tool onto the hub and bearing assembly and secure it into place using the wheel lug nuts.
  16.  
  17. Protect wheel stud threads by installing a wheel lug nut onto a wheel stud. Install a flat blade prying tool to prevent the hub from turning. Using the puller tool, force the halfshaft outer stub axle from the hub and bearing assembly.
  18.  
  19. Dislodge the inner Tripod joint from the stub shaft retaining snapring on the transaxle. To do this, insert a prybar between the transaxle case and the inner Tripod joint and pry on Tripod joint.
  20.  

Do not try to remove the inner Tripod joint from the transaxle stub shaft at this time. Only disengage the inner Tripod joint from the retainer snapring.

  1. Remove the strut assembly-to-steering knuckle attaching bolts from the strut assembly.
  2.  


WARNING
The strut assembly to steering knuckle bolts are serrated (toothed) where they go through the strut assembly and steering knuckle. When removing the bolts, turn the nuts off the bolt. Do not turn the bolts in the steering knuckle or damage to the steering knuckle will result.

  1. Separate the top of the steering knuckle from the lower end of the strut.
  2.  
  3. Hold the outer joint assembly with one hand. Grasp the steering knuckle with the other hand and rotate it out and to the rear of the vehicle, until the outer CV-joint clears the hub and bearing assembly.
  4.  


WARNING
When removing the outer CV-joint from the hub and bearing assembly, do not allow the flange disc on the hub and bearing assembly to become damaged. If this happens, dirt and water can enter the bearing which will cause premature bearing failure.

  1. Remove the halfshaft inner joint from the transaxle stub shaft by grasping the inner Tripod joint and the interconnecting shaft and pulling both pieces at the same time. Take care not to pull on the interconnecting shaft to remove or separation of the spider assembly will occur.
  2.  

To install:
  1. Replace the inner Tripod joint retaining circlip and O-ring seal on the transaxle stub shaft. These components are not reusable and must be replaced whenever the halfshaft is removed.
  2.  
  3. Apply an even coat of grease on the splines of the inner Tripod joint, where the O-ring seats against the Tripod joint.
  4.  
  5. Install the halfshaft through the hole in the splash shield. Grasp the inner joint in 1 hand and interconnecting shaft in the other. Align the inner Tripod joint spline with the stub shaft spline on the transaxle. Use a rocking motion with the inner Tripod joint to get it past the circlip on the transaxle stub shaft.
  6.  
  7. Continue pushing Tripod joint onto transaxle stub shaft until it stops moving. The O-ring on the stub shaft should not be visible when the inner Tripod joint is fully installed. Check that the inner Tripod joint is locked in position by grasping the inner joint and pulling. If locked in position, the joint will not move on the stub shaft.
  8.  
  9. Hold the outer CV-joint assembly with one hand. Grasp the steering knuckle with the other and rotate it out and to the rear of the vehicle. Install the outer CV-joint into the hub and bearing assembly.
  10.  
  11. Install the top of the steering knuckle into the strut assembly. Align the steering knuckle to strut assembly mounting holes.
  12.  
  13. Install the strut assembly-to-steering knuckle attaching bolts. Install the nuts to the attaching bolts and while holding the bolt heads, tighten nuts to 125 ft. lbs. (170 Nm). Turn the nuts on the bolts. Do NOT turn the bolts.
  14.  
  15. Install a new hub and bearing assembly-to-stub shaft retainer nut. Tighten but do not torque the nut at this time.
  16.  
  17. Install the speed sensor cable routing bracket and secure attaching screw.
  18.  
  19. Install the brake rotor and the caliper assembly. Install the caliper guide pin bolts to steering knuckle and tighten to 30 ft. lbs. (41 Nm).
  20.  
  21. Install the front wheels and lug nuts. Torque the lug nuts, in sequence, to 95-100 ft. lbs. (129-135 Nm). Lower the vehicle to the ground. Pump the brakes until a firm pedal is obtained.
  22.  
  23. Apply the brakes and torque the new stub shaft-to-hub and bearing assembly retainer nut to 120 ft. lbs. (163 Nm).
  24.  


WARNING
When tightening the stub shaft retaining nut, be careful not to exceed the maximum torque specification of 120 ft. lbs. (163 Nm). If this specification is exceeded, failure of the halfshaft could result.

  1. Reconnect the negative battery cable. Road test vehicle to check for noise or vibration.

The inner tripod joint boots used on the Chrysler LH vehicles use no internal retention in the tripod housing to keep the joint assembly retained in the housing. Therefore, do not pull on the interconnecting shaft to separate the tripod housing from the transaxle stub shaft. This will damage the inner boot.

Inner Tripod Boot
  1. Disconnect the negative battery cable.
  2.  
  3. Raise and support the vehicle safely. Remove the appropriate wheel.
  4.  
  5. Remove the halfshaft requiring boot replacement.
  6.  
  7. Remove the large boot clamp which retains the inner Tripod joint boot to the Tripod joint housing. Remove the small clamp which retains the inner Tripod joint boot to the interconnecting shaft. Discard the clamps.
  8.  
  9. Remove the boot from the Tripod joint housing and slide it down the shaft.
  10.  
  11. Slide the interconnecting shaft and spider assembly out of the Tripod joint housing.
  12.  


WARNING
When removing the spider joint from the tripod housing, be careful not to allow the rollers and needle bearings to fall off of the spider assembly.

  1. Remove the snapring which retains the spider assembly to the shaft. Slide the spider assembly off the shaft. If the spider assembly will not come off the shaft, tap on the spider body using a brass drift. Do not hit the outer Tripod bearings in an attempt to remove the spider assembly.
  2.  
  3. Slide the boot from the interconnecting shaft.
  4.  
  5. Thoroughly clean and inspect the spider assembly, Tripod joint housing and interconnecting shaft for excess wear.
  6.  

If any parts show excess wear, the halfshaft assembly will require replacement. Component parts of the halfshaft assemblies are not serviceable. The inner Tripod joint boot is made of 2 types of material depending on the application. The high temperature application is made from silicone rubber, which is soft. The standard temperature application boot is composed of hytrel plastic which is hard. The replacement boot must be of the same composition as the original boot.

To install:
  1. Slide the new boot retainer clamp onto the interconnecting shaft followed by the new boot.
  2.  
  3. Install the spider assembly onto the shaft and install snapring. Make sure the snapring is fully seated in the groove of the shaft.
  4.  
  5. Distribute one half of the grease provided in the boot service kit into the Tripod housing. Put the remaining grease into the CV-boot.
  6.  
  7. Slide the spider assembly and the interconnecting shaft into the Tripod joint housing. Position the sealing boot over the retaining groove on the interconnecting shaft. Be sure that only the thinnest groove on the interconnecting shaft is visible.
  8.  
  9. Install the boot retaining clamp in position over the boot and crimp closed using tool C-4975 or equivalent.
  10.  


WARNING
Before crimping the CV-boot-to-Tripod housing clamp, the inner joint must be at the correct stroke position. This is required to ensure that the proper amount of air is inside the boot before the clamp is crimped. Failure to do this will result in inner CV-boot failure.

  1. Position the sealing boot into the Tripod housing retainer groove. Install clamp on boot. Make sure the inner Tripod joint is in at the correct position. The distance between the inner clamp and the end of the housing is 8.5 inch (216mm) for standard application joint or 7.8 inch (198mm) on high temperature applications. With the distance at the correct value, crimp the sealing boot onto the Tripod housing using tool C-4975 or equivalent.
  2.  
  3. Install the halfshaft into the vehicle.
  4.  
  5. Install the wheel and lug nuts. Torque the lug nuts, in a star pattern sequence, to 95-100 ft. lbs. (129-135 Nm).
  6.  
  7. Lower the vehicle. Reconnect the negative battery cable.

  12.  
  13. Slide boot off the shaft. Thoroughly clean and inspect the CV-joint assembly and interconnecting shaft for damage or excess wear.
  14.  

If any parts show signs of excess wear, the halfshaft assembly will require replacement. Component parts for the halfshaft assemblies are not serviceable.

To install:
  1. Slide a new seal boot-to-interconnecting shaft retainer clamp, followed by the new boot, onto the shaft. Install the outer CV-joint assembly onto the interconnecting shaft pushing on the shaft until the retaining snapring is seated in the groove on the shaft. Be sure the snapring is fully seated.
  2.  
  3. Distribute one half of the grease provided in the boot service kit into the joint housing. Put the remaining grease into the CV-boot. Do NOT use any other type of grease.
