Mitsubishi Eclipse 1990-1998 Repair Guide

Halfshafts

Print

REMOVAL & INSTALLATION



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 2 types of joints used are the Birfield Joint, (B.J.) and the Tripod Joint (T.J.). Special grease and clamps are used with these joints and is normally supplied with the replacement joint and/or boot kit. Do not use regular chassis grease.

1990-94 Vehicles

See Figures 1 and 2

If the vehicle is going to be rolled while the halfshafts are out of the vehicle, obtain 2 outer CV-joints or proper equivalent tools and install to the hubs. If the vehicle is rolled without the proper torque applied to the front wheel bearings, the bearings will no longer be usable.

  1. Disconnect the negative battery cable.
  2.  
  3. Raise and safely support the vehicle. Remove the wheel and tire assemblies.
  4.  
  5. Remove the cotter pin, halfshaft nut and washer. Discard the cotter pin.
  6.  
  7. Raise the vehicle and support safely. If removing the right halfshaft, remove the retainer bolt and the speedometer drive from the right extension housing.
  8.  
  9. Remove the lower ball joint and the tie rod end from the steering knuckle.
  10.  
  11. On halfshafts with an inner shaft (AWD vehicles), remove the center support bearing bracket bolts and washers. Now 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.
  12.  
  13. On one piece halfshafts (FWD vehicles), remove the halfshaft from the hub/knuckle 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.
  14.  


WARNING
Do not pull on the shaft; doing so damages the inboard joint. Do not insert the prybar too far or the oil seal in the case may be damaged.

OVERHAUL



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 2 types of joints used are the Birfield Joint, (B.J.) and the Tripod Joint (T.J.). Special grease and clamps are used with these joints and is normally supplied with the replacement joint and/or boot kit. Do not use regular chassis grease.

Correct installation of the CV-boot is essential for its longevity. A specification is given for the distance between the large and small boot bands. 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.

FWD Vehicle
1990-94 VEHICLES

See Figures 5 and 6

Both of the halfshaft boots are going to be removed from the T.J. case side of the halfshaft.

  1. Disconnect the negative battery cable. Remove the halfshaft from the vehicle.
  2.  
  3. Remove the T.J. boot bands from the boot. Side cutter pliers can be used to cut off the metal retaining bands. Remove the T.J. case from the halfshaft.
  4.  
  5. Remove the snapring next to the tripod joint spider assembly from the halfshaft with snapring pliers. Remove the spider assembly from the shaft.
  6.  

Do not disassemble the spider and use care in handling.

  1. If the boot is be reused, wrap vinyl tape around the spline part of the shaft so the boot will not be damaged when removed. Remove the dynamic damper, if used, and boots from the shaft.
  2.

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. 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).
  4.  
  5. Secure the boot bands with the halfshaft in a horizontal position. Make sure the boot span on the halfshaft is 3.23-3.47 in. (82-88mm) in length.
  6.  
  7. Install halfshaft into vehicle.
  8.
