Halfshaft

Print

REMOVAL & INSTALLATION



The halfshaft assembly consists of a sub-axle shaft and a halfshaft with 2 constant velocity (CV) joints. The CV-joints are factory packed with special grease and enclosed in sealed rubber boots. The outer joint cannot be disassembled except for removal of the boot.

1986-89 Integra

CAUTION
Spindle nut torque is very high. Tighten or loosen the spindle nut only with the vehicle on the ground. Attempting to loosen or torque the spindle nut while the vehicle is on jack stands or a lift may cause the vehicle to fall.

  1. Loosen, but do not remove, the front wheel spindle nut with a 32mm socket.
  2.  
  3. Raise and safely support the vehicle.
  4.  
  5. Drain the transaxle.
  6.  
  7. Remove the wheel lug nuts and the wheel.
  8.  
  9. Remove the spindle nut.
  10.  
  11. Using a floor jack to support the lower control arm, remove the lower arm ball joint cotter pin and nut.
  12.  

Make sure a floor jack is positioned securely under the lower control arm, at the ball joint. Otherwise, the lower control arm may jump suddenly away from the steering knuckle as the ball joint is removed.

  1. Separate the ball joint from the front hub with a ball joint puller.
  2.  
  3. Slowly lower the floor jack to lower the control arm.
  4.  
  5. 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.
  6.  

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.
  2.  

To install:
  1. If either the inboard or outboard joint boot bands have been removed for inspection or disassembly of the joint (only the inboard joint can be disassembled), be sure to repack the joint with a sufficient amount of CV-joint grease.
  2.  
  3. Make sure the CV-joint sub-axle bottoms during installation so the spring clip may hold the halfshaft securely in the differential/intermediate shaft groove. Always replace the spring clip with a new one.
  4.  
  5. Torque the ball joint nut to 29 ft. lbs. (40 Nm), then tighten as required to insert a new cotter pin.
  6.  
  7. With the vehicle on the ground, torque the spindle nut to 134 ft. lbs. (185 Nm) and stake the nut.
  8.  

Except 1986-89 Integra

CAUTION
Spindle nut torque is very high. Tighten or loosen the spindle nut only with the vehicle on the ground. Attempting to loosen or torque the spindle nut while the vehicle is on jack stands or a lift may cause the vehicle to fall.

  1. With the vehicle on the ground, raise the locking tab on the spindle nut and loosen it with a suitable socket.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Raise and safely support the vehicle and remove the spindle nut and front wheels.
  6.  
  7. If removing the right side halfshaft, drain the transaxle or differential oil.
  8.  
  9. Remove the damper fork nut and damper pinch bolt. Remove the damper fork.
  10.  
  11. Remove the lower ball joint nut and separate the lower ball joint using a suitable puller with the pawls applied to the lower arm.
  12.  
  13. Pull the knuckle outward and remove the halfshaft outboard CV-joint from the knuckle using a suitable plastic mallet.
  14.  
  15. 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.
  16.  

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.
  2.  
  3. To remove the intermediate shaft, remove the 3 bolts. Lower the bearing support close to the steering gear box and remove the intermediate shaft from the differential. To prevent any damage from the differential oil seal, hold the intermediate shaft horizontal until it is clear of the differential.
  4.  

To install:
  1. If either the inboard or outboard joint boot bands have been removed for inspection or disassembly of the joint (only the inboard joint can be disassembled), be sure to repack the joint with a sufficient amount of the correct CV-joint grease.
  2.  
  3. 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 subaxle bottoms in the differential or the intermediate shaft.
  4.  
  5. Torque the ball joint nut to 40 ft. lbs. (55 Nm) on Integra, 43 ft. lbs. (60 Nm) on Vigor or 54 ft. lbs. (75 Nm) on Legend. Then tighten the nut as required to install a new cotter pin.
  6.  
  7. Torque the lower damper nut and bolt to 47 ft. lbs. (65 Nm) and the upper pinch bolt to 32 ft. lbs. (44 Nm).
  8.  
  9. With the vehicle on the ground, torque the spindle nut, then stake the nut.

    Vigor-180 ft. lbs. (250 Nm)
     
    1986-90 Legend-180 ft. lbs. (250 Nm)
     
    1991-93 Legend-242 ft. lbs. (335 Nm)
