  1. While the vehicle is still on the ground, remove the cotter pin, and loosen the axle nut.
  2.  
  3. Raise the vehicle and support it safely.
  4.  
  5. If equipped with ABS, remove the front wheel speed sensor.
  6.  
  7. If equipped with Active Electronic Control Suspension (Active-ECS), perform the following:
  8.  

  1. Loosen the nut that secures the air line to the to the top of the strut and discard the O-ring.
  2.  
  3. Remove the bolts that secure the actuator to the top of the strut and remove the component. Disconnect the wiring harness.
  4.  

  1. Disconnect the lower ball joint and the tie rod end from the steering knuckle.
  2.  
  3. Remove the axle nut and the washer.
  4.  
  5. If removing the left side axle with an inner shaft, remove the center support bearing bracket bolts and washers. Then, remove the halfshaft by setting up a puller on the outside wheel hub and pushing the halfshaft from the front hub. Tap the shaft union at the joint case with a plastic hammer to remove the halfshaft and inner shaft from the transaxle.
  6.  
  7. If removing right side axle shafts without an inner shaft, remove the halfshaft by setting up a puller on the outside wheel hub and pushing the halfshaft from the front hub. After pressing the outer shaft, insert a prybar between the transaxle case and the halfshaft and pry the shaft from the transaxle.
  8.  


NOTE
Do not pull on the shaft; doing so damages the inboard joint.

To install:

  1. Replace the circlips on the ends of the halfshafts.
  2.  
  3. Insert the halfshaft into the transaxle. Be sure it is fully seated.
  4.  
  5. Pull the strut assembly out and install the other end to the hub.
  6.  
  7. Install the center bearing bracket bolts and tighten to 33 ft. lbs. (45 Nm).
  8.  
  9. Install the washer on the axle shaft so the chamfered edge faces outward. Install the axle nut, but do not tighten it fully at this time.
  10.  
  11. Connect the ball joint to the steering knuckle. Torque the new retaining nut to 43-52 ft. lbs. (60-72 Nm) and secure with a new cotter pin.
  12.  
  13. Connect the tie rod end to the steering knuckle. Torque the retaining nut to 21 ft. lbs. (29 Nm) and secure with a new cotter pin.
  14.  
  15. If equipped with ABS, install the front wheel speed sensor.
  16.  
  17. If equipped with Active-ECS, perform the following:
  18.  

  1. Install the air line with a new O-ring.
  2.  
  3. Install the actuator to the top of the strut. Connect the wiring harness.
  4.  

  1. Install the wheel and lower the vehicle to the floor.
  2.  
  3. Tighten the axle nut to 145-188 ft. lbs. (200-260 Nm) and secure with a new cotter pin.
  4.  

CV-JOINTS 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.).


NOTE
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.


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

Double Offset Joint

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.
  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.  

Except Double Offset Joint
  1. Disconnect the negative battery cable. Remove the halfshaft.
  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.
