Halfshaft

Print

The following procedures cover vehicles equipped with manual or automatic transaxles.

REMOVAL & INSTALLATION



The outer CV-joint cannot be removed from the halfshaft. Replacement of a CV-joint boot requires removal of the halfshaft. If the outer CV-joint has failed the entire shaft must be replaced as an assembly.

  1. With the vehicle on the ground, raise the locking tab on the spindle nut and loosen it with a suitable socket.
  2.

  4.  
  5. Drain the differential or transaxle lubricant.
  6.  
  7. Remove the strut fork nut and strut pinch bolt. Remove the strut fork.
  8.  
  9. Remove the lower ball joint nut, then separate the lower ball joint using a suitable ball joint removal tool.
  10.  
  11. Pull the knuckle outward and remove the halfshaft outboard CV-joint from the knuckle using a plastic mallet.
  12.  
  13. Using a small prybar with a 3.5 x 7mm tip, carefully pry out the inboard CV-joint approximately 1 / 2 in. (13mm) in order to force the spring clip out of the groove in the differential side gears.
  14.  


WARNING
Be careful not to damage the oil seal. Do not pull on the inboard CV-joint, it may come apart.

  1. Pull the halfshaft out of the differential or the intermediate shaft. Replace the spring clip on the end of the inboard joint.
  2.  
  3. Be sure to mark the roller grooves during disassembly to ensure proper positioning during reassembly.
  4.  
  5. Remove the front and rear boot retaining bands, then separate the inboard joint from the halfshaft assembly.
  6.  
  7. Mark the spider gear and the driveshaft so they can be installed in their original positions.
  8.  
  9. Remove snapring, spider gear, then remove the stopper ring.
  10.  
  11. Be sure to mark the position on the shaft where the dynamic strut goes, to ensure it will be reinstalled in its original position. Remove the inboard CV-joint boot, dynamic strut, then the outboard CV-joint boot.
  12.  

To install:
  1. Wrap the spline with vinyl tape to prevent damage to the boots. Install the outboard boot, dynamic strut, and inboard boot, then remove the vinyl tape.
  2.  
  3. Install the stopper ring onto the halfshaft groove, then install the spider gear in its original position by aligning the marks.
  4.  
  5. Fit the snapring into the halfshaft groove.
  6.  
  7. Pack the outboard joint boot with CV-joint grease only. Do not use a substitute, or mix types of grease.
  8.  
  9. Fit the rollers to the spider gear with their high shoulders facing outward. Reinstall the rollers in their original positions on the spider gear.
  10.  
  11. Pack the inboard joint boot with a suitable CV-joint grease.
  12.  
  13. Fit the inboard joint onto the halfshaft. Hold the halfshaft assembly so the inboard joint points up to prevent it from falling off.
  14.  
  15. With the boots installed, adjust the CV-joints in or out to place the inner boot ends in the original positions.
  16.  
  17. Install the new boot bands on the boots and bend both sets of locking tabs. Lightly tap on the locking tabs to ensure a good fit.
  18.  
  19. Always use a new set ring whenever the driveshaft is being installed. Be sure the driveshaft locks in the differential side gear groove and that the CV-joint stub-axle bottoms in the differential or the intermediate shaft.
  20.  
  21. Tighten the ball joint nut to the proper specification for your vehicle, as follows:

    The ball joint nut to 29-35 ft. lbs. (39-47 Nm). from 8

  32.  

CV-JOINT OVERHAUL



These vehicles use several different types of joints. Engine size, transaxle type, whether the joint is an inboard or outboard joint, even which side of the vehicle is being serviced could make a difference in joint type. Be sure to properly identify the joint before attempting joint or boot replacement. Look for identification numbers at the large end of the boots and/or on the end of the metal retainer bands.

The 3 types of joints used are the Birfield Joint, (B.J.), the Tripod Joint (T.J.) and the Double Offset Joint (D.O.J.).

Do not disassemble a Birfield joint. Service with a new joint or clean and repack using a new boot kit.

The distance between the large and small boot bands is important and should be checked prior to, and after boot service. This is so the boot will not be installed either too loose or too tight, which could cause early wear and cracking, allowing the grease to get out and water and dirt in, leading to early joint failure.

The driveshaft joints use special grease; do not add any grease other than that supplied with the kit.

Double Offset Joint (D.O.J.)

The Double Offset Joint (D.O.J.) is bigger than other joints and, in these applications, is normally used as an inboard joint.

  1. Remove the halfshaft from the vehicle, as outlined earlier.
  2.  
  3. Side cutter pliers can be used to cut the metal retaining bands. Remove the boot from the joint outer race.
  4.  
  5. Locate and remove the large circlip at the base of the joint. Remove the outer race (the body of the joint).
  6.  
  7. Remove the small snapring and take off the inner race, cage and balls as an assembly. Clean the inner race, cage and balls without disassembling.
  8.  
  9. If the boot is to be reused, wipe the grease from the splines and wrap the splines in vinyl tape before sliding the boot from the shaft.
  10.  
  11. Remove the inner (D.O.J.) boot from the shaft. If the outer (B.J.) boot is to be replaced, remove the boot retainer rings and slide the boot down and off of the shaft at this time.
  12.  

To install:
  1. Be sure to tape the shaft splines before installing the boots. Fill the inside of the boot with the specified grease. Often the grease supplied in the replacement parts kit is meant to be divided in half, with half being used to lubricate the joint and half being used inside the boot.
  2.  
  3. Install the cage onto the halfshaft so the small diameter side of the cage is installed first. With a brass drift pin, tap lightly and evenly around the inner race to install the race until it comes into contact with the rib of the shaft. Apply the specified grease to the inner race and cage and fit them together. Insert the balls into the cage.
  4.  
  5. Install the outer race (the body of the joint) after filling with the specified grease. The outer race should be filled with this grease.
  6.  
  7. Tighten the boot bands securely. Make sure the distance between the boot bands is correct.
  8.  
  9. Install the halfshaft to the vehicle.
  10.  

Tripod Joint (T.J.)

  1. Disconnect the negative battery cable. Remove the halfshaft from the vehicle.
  2.  
  3. Use side cutter pliers to remove the metal retaining bands from the boot(s) that will be removed. Slide the boot from the T.J. case.
  4.  
  5. Remove the snapring and the tripod joint spider assembly from the halfshaft. Do not disassemble the spider and use care in handling.
  6.  
  7. If the boot is be reused, wrap vinyl tape around the spline part of the shaft so the boot(s) will not be damaged when removed. Remove the dynamic damper, if used, and the boots from the shaft.
  8.  

To install:
  1. Double check that the correct replacement parts are being installed. Wrap vinyl tape around the splines to protect the boot and install the boots and damper, if used, in the correct order.
  2.  
  3. Install the joint spider assembly to the shaft and install the snapring.
  4.  
  5. Fill the inside of the boot with the specified grease. Often the grease supplied in the replacement parts kit is meant to be divided in half, with half being used to lubricate the joint and half being used inside the boot. Keep grease off the rubber part of the dynamic damper (if used).
  6.  
  7. Secure the boot bands with the halfshaft in a horizontal position. Make sure distance between boot bands is correct.
  8.  
  9. Install the halfshaft to the vehicle and reconnect the negative battery cable.
  10.
