  1. Remove the halfshaft from the vehicle, then clamp it in a vise. Use soft jaws or wood blocks to protect the finish on the halfshaft.
  2.  
  3. Cut and remove the boot retaining clamps with wire cutters. Some technicians may use a grinder to cut the bands, especially the smaller swaged band. Use care not to cut through the boot and damage the sealing surface of the CV-joint housing.

  1. Separate the boot from the inner CV-joint the large diameter and slide the boot away from the joint along the axle shaft.
  2.  
  3. There is a three-arm bearing called a "spider" that is retained on the halfshaft, or axle shaft, by a snapring. Move the CV-joint housing away from the spider to locate the snapring which is in a groove on the end of the drive axle. Spread the ears of the ring and remove the retaining ring along with the spider. Use the same pliers to remove the spacer ring which sits next to the spider on the axle shaft.
  4.  
  5. Slide the CV-joint boot from the axle shaft. If just the boot is being replaced, and the joint is still in good condition (the boot is being replaced before the old one failed), it is possible to reassemble using a new boot and the special grease usually found in a Boot Kit. Flush the grease from the joint and repack the boot with half of the grease provided with the new boot. If, however, the boot was torn and the joint contaminated with water or dirt, the joint will have to be replaced or overhauled, using the procedures found in this section.
  6.  
  7. Clean all parts well. The spider assembly and the housing must be thoroughly cleaned with a suitable solvent. All traces of old grease and any contaminates must be removed. Dry all parts. Refill the housing with approximately half of the grease from the service kit and provided with the new boot. The other half of the grease goes inside the replacement boot.
  8.  
  9. Install the new boot and clamps (do not tighten yet) on the halfshaft. Make sure the boot is pointing in the correct direction. With the boot in place, install the spacer snapring, the spider assembly and the outer retaining ring. Make sure all retaining snaprings are properly seated in their grooves. Position the new clamps on the boot. The factory uses a special swaging tool for the original installation. Service replacement CV-boot kits normally come with clamps that can be tightened with pliers.
  10.  


NOTE
The seal must not be dimpled, stretched or out of shape in any way. If the seal is NOT shaped correctly, carefully insert a thin, flat blunt tool (NO SHARP EDGES) between the large seal opening and the tripot bushing to equalize the pressure. Shape the seal properly by hand and remove the tool.

NOTE
A number of components will not be reused. Procure the necessary parts before starting this job. CV-Boot Repair Kits normally come with all the parts required, but you should check that all parts are on hand before starting this procedure.

  1. Remove the halfshaft from the vehicle, then clamp in a vise. Use soft jaws or wood blocks to protect the finish on the halfshaft.
  2.  
  3. Cut and remove the boot retaining clamps with wire cutters.
  4.  
  5. Separate the boot from the CV-joint race at the large diameter and slide the boot away from the joint along the axle shaft.
  6.  
  7. Wipe the grease from the face of the CV-joint inner race.
  8.  
  9. Locate the retaining ring located on the shaft where is passes through the big end of the joint. It may be under a thick layer of CV-joint grease. Spread the ears of the retaining ring with lock ring pliers and remove the outer joint assembly from the halfshaft.
  10.  
  11. Slide the CV-joint boot from the axle shaft. If just the boot is being replaced, and the joint is still in good condition (the boot is being replaced before the old one failed), it is possible to reassemble using a new boot and the special grease usually found in a CV-boot kit. Flush the grease from the joint and repack the boot with half of the grease provided with the new boot. If, however, the boot was torn and the joint contaminated with water or dirt, the joint will have to be replaced or overhauled, using the procedures found in this section.

  1. Install the new boot and clamps (do not tighten yet) on the axle shaft. Make sure the boot is pointing in the correct direction. With the boot in place, install the joint to the drive axle shaft and snap the race retaining ring into place. Put the remainder of the special CV-Joint grease that came in the boot kit, into the joint. Position the new clamp on the boot. The factory uses a special swaging tool for the original installation. Service replacement CV-boot kits normally come with clamps that can be tightened with pliers.

Inspection



Front wheel drive vehicles use drive axles (also called halfshafts) which are flexible shaft assemblies that transmit the rotational forces from the transaxle to the front wheel assemblies. The axle assembly is made up of an inner and outer Constant Velocity Joint (commonly called a CV-Joint) connected to an axle shaft. The inner joint is completely flexible and can move in-and-out as the suspension also moves. The outer joint is also flexible but cannot move in-and-out. These CV-joints are expensive, precision-made assemblies and are protected from the elements by flexible covers called CV-boots. If the boot becomes damaged or torn, the special CV-joint lubrication can run out and dirt, water and debris will get in, damaging the precision surfaces and quickly ruining the joint.

Fig. All torn boots should be replaced immediately

The CV-boots should be checked for damage every time the oil is changed and any other time the vehicle is raised for service. Heavy grease thrown around the inside of the front wheel(s) and on the front brake caliper can be an indication of a torn boot. Thoroughly check the boots for missing clamps and tears. If the boot is damaged, it should be replaced immediately. Please refer to Section 7 for the procedure.

Overhaul



Outer CV-Joint
  1. Remove the halfshaft and separate the outer CV-joint from the axle shaft following the CV-boot removal and installation procedure. 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 degrees 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.
  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.

Fig. Assembling the overhauled outer CV-joint to the halfshaft

To install:

  1. Lightly coat the ball grooves with the provided special CV 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.
  6.  
  7. Install the joint onto the axle. Make sure the retaining ring is properly seated in its groove.
  8.  
  9. Install the boot and clamps using the procedures for Boot Removal and Installation found in this section. Make sure the lip on the rubber boot is in the proper groove in the outer race.
  10.  
  11. Install the halfshaft in the vehicle, as outlined earlier in this section.
