REMOVAL & INSTALLATION




WARNING
Be careful not to over-extend the inboard CV-joint. When either end of the halfshaft is disconnected, over-extension of the joint could result in separation of internal components and possible joint failure. Use CV-joint boot protectors any time service is performed on or near the halfshafts. If these precautions are not taken, boot or interior joint damage may result, with possible eventual joint failure.

  1. Raise and safely support the vehicle.
  2.  
  3. Remove the wheel and tire assembly.
  4.  
  5. Install modified boot protector J-34754 or equivalent, on the outer CV-joint.
  6.  
  7. Insert a drift punch into the caliper and rotor to prevent the rotor from turning, then remove the hub nut.
  8.  
  9. Disconnect the stabilizer link, if necessary.
  10.  
  11. Remove the ball joint cotter pin and nut. Loosen the ball joint in the knuckle using a suitable ball joint tool, being careful not to damage the ball joint and grease seal. If removing the right halfshaft, turn the wheel to the left; if removing the left halfshaft, turn the wheel to the right.
  12.  
  13. Using a prybar between the suspension support and the lower control arm, separate the ball joint from the steering knuckle.
  14.  
  15. Partially install the hub nut to protect the threads, then remove the halfshaft from the hub using tool J-28733 or equivalent. Move the strut and knuckle rearward.
  16.  
  17. Separate the halfshaft from the transaxle using a suitable prybar and a wood block fulcrum to protect the transaxle case.
  18.  


WARNING
If equipped with anti-lock brakes, be careful not to damage the toothed sensor ring on the halfshaft or the wheel speed sensor on the steering knuckle.

To install:

  1. If installing the right side halfshaft, install tool J-37292-A or equivalent, so it can be pulled out after the halfshaft is installed.
  2.  
  3. Install the halfshaft into the transaxle by placing a small prybar into the groove on the inner CV-joint housing and tapping until seated. Verify that the halfshaft snapring is seated by grasping the inner CV-joint housing and pulling outward. DO NOT PULL ON THE HALFSHAFT.
  4.  
  5. Install the halfshaft into the hub and bearing assembly. Loosely install a new hub nut (and washer, if equipped).
  6.  
  7. Connect the ball joint to the steering knuckle and install the nut.
  8.  
  9. On Deville and Fleetwood, tighten the ball joint nut to 88 inch lbs. (10 Nm), then tighten to 41 ft. lbs. (55 Nm) minimum. Install a new cotter pin. If it is necessary to align the slot in the nut, tighten the nut (up to one more flats).
  10.  
  11. On Eldorado and Seville, tighten the ball joint nut to 84 inch lbs. (10 Nm), then an additional 120 degrees. A minimum torque of 37 ft. lbs. (50 Nm) must be obtained when tightening the nut. If the minimum torque is not obtained, inspect for stripped threads. If the threads are okay, replace the ball joint and knuckle. Install a new cotter pin after the ball joint nut has been torqued. If necessary, turn the nut up to an additional 60 degrees (one flat) to allow for installation of the cotter pin. NEVER loosen the nut to allow for cotter pin installation.
  12.  
  13. Insert a drift punch into the caliper and rotor to prevent the rotor from turning. On 1990-91 vehicles, tighten the hub nut to 185 ft. lbs. (251 Nm). On 1992-up vehicles, tighten the hub nut to 110 ft. lbs. (145 Nm), except on Deville and Fleetwood equipped with J55 brake option, in which case the torque is 130 ft. lbs. (177 Nm).
  14.  
  15. Connect the stabilizer link, if removed.
  16.  
  17. Remove the boot protector.
  18.  
  19. If tool J-37292-A or equivalent, was installed, remove it by pulling in line with the handle. Make sure it is completely removed and no pieces are left inside the transaxle.
  20.  
  21. Install the wheel and tire assembly and lower the vehicle.
  22.

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.
  10.
