Toyota Corolla 1970-1987 Repair Guide

Halfshafts

Print

The axleshafts on front wheel drive vehicles are often referred to as halfshaft assemblies

The halfshaft CV-joints are packed with grease for lubrication during assembly. The joints are then covered with rubber CV-boots for protection. If a boot becomes torn or otherwise damaged, it should be replaced immediately to prevent possible damage to the CV-joints from dirt or moisture. The CV-boots should be inspected any time the vehicle is raised to help prevent costly repairs should a CV-joint fail.

REMOVAL & INSTALLATION



See Figures 1 through 16

  1. Unless air tools are available, remove the cotter pin and hub nut lock before the vehicle is raised. Have an assistant step on the brake pedal and at the same time, loosen and remove the bearing locknut.
  2.  
  3. Raise the front of the vehicle and support it with jackstands. Remove the tires.

Be sure to cover the halfshaft input hole

  1. Installation is in the reverse order of removal. Please note the following:
    1. Install the outboard side of the shaft into the axle hub and then insert the inner end into the differential. Finger tighten the six nuts. Be careful not to damage the boots during installation.
    2.  
    3. Tighten the steering knuckle-to-lower arm bolts to 47 ft. lbs. (64 Nm).
    4.  
    5. With the vehicle on the ground, tighten the bearing locknut to 137 ft. lbs. (186 Nm) and be sure to use a new cotter pin on the locknut cap.
    6.

OVERHAUL



See Figures 17, 18, 19 and 20

  1. Remove the halfshaft from the vehicle. For details, please refer to the removal and installation procedure found earlier in this section.
  2.  
  3. Before disassembling a halfshaft, check the following to determine it's condition:
    1. Check to see that there is no play in the outboard joint.
    2.  
    3. Check to see that the inboard joint slides smoothly in the thrust direction.
    4.  
    5. Check to see that there is no abnormal play in the radial direction of the inboard joint.
    6.

Fig. Fig. 19: Lock the boot clamp as shown

  1. Place matchmarks on the inboard joint tulip and on the tripod. Remove the tulip from the halfshaft. When matchmarking the tulip to the tripod, never punch the marks.
  2.  
  3. Remove the snapring on the tripod with snapring pliers. Punch matchmarks on the shaft and the tripod and then gently tap the tripod off of the shaft. Never tap on the roller.
  4.  
  5. Remove both boots.
  6.  
  7. Tape the halfshaft splines, then install the boot and a new clamp to the outboard joint.
  8.  
  9. Repeat Step 1 for the inboard joint.
  10.  
  11. Position the beveled side of the tripod axial spline toward the outboard joint. Align the matchmarks made previously, then using a brass drift or hammer, tap the tripod onto the halfshaft.
  12.  
  13. Install a new snapring.
  14.  
  15. Attach the boot to the outboard joint. Pack the boot with grease supplied in the boot kit.
  16.  
  17. Pack the tulip with grease, align the matchmarks and then install the tulip to the halfshaft.
  18.  
  19. Install the boots, making sure that the boot is in the shaft groove. Install new boot clamps and lock them into position as shown in the illustration.
  20.  

Make sure that the boot is not stretched or contracted when the halfshaft is at its standard length. The halfshaft length for the gasoline engine is right side 27.48 in. (698.5mm) and left side 16.54 in. (420.5mm). The standard length for the diesel engine is right side 27.76 in. (705.5mm) and left side 16.46 in. (418.5mm)

  1. Once the halfshaft is properly assembled, install the shaft back in the vehicle. BE VERY careful not to tear the new boots upon installation or you will have to start all over again.
