OVERHAUL



200SX(Halfshaft Assembly)

See Figures 4 through 14

When overhauling the halfshaft assembly on the 240SX use this procedure as a service guide. Review the complete procedure before starting.

  1. Clamp the halfshaft in a vise using soft jaws.
  2.  
  3. Using pliers, pry the plug from the wheel side of the halfshaft.
  4.  
  5. Remove the plug seal, spring, spring cap and the boot bands.
  6.  

Never reuse boot bands once they have been removed.

  1. Scribe a matchmark on the spider assembly and the halfshaft.
  2.  
  3. Remove the spider assembly with a press. Do not attempt to touch the contact surface of the halfshaft end at the spring cap or housing subassembly. Always support the halfshaft with your hand while you are removing the spider assembly.
  4.  
  5. Draw out the slide joint boot and the boot bands.
  6.  
  7. Loosen the vise and turn the halfshaft around so that the differential end is up.
  8.  
  9. Using a hacksaw, cut off the hold joint boot assembly and then remove the housing subassembly.
  10.  

When cutting the hold joint boot assembly, make sure that the halfshaft is pushed into the housing subassembly in order to prevent the spider assembly from being scratched. Never reuse the boot assembly after it has been removed.

  1. Remove and discard the boot band and then remove the spider assembly as detailed in Steps 4-5.
  2.  
  3. Cut off the remaining part of the hold joint boot assembly and remove it from the housing subassembly. Be careful not to scratch the housing ring or assembly.

  9. Remove all remaining parts of the hold joint boot assembly and the boot band from the halfshaft.
  10.  
  11. Attach a housing ring, an O-ring, a housing subassembly and a housing cover to a new hold joint boot assembly. Place the assembled unit flange in a vise. Don't forget to grease the O-ring.
  12.  
  13. Place a board on a housing cover to prevent it from being scratched. Use a mallet and bend the edge over along the entire circumference.
  14.  
  15. Withdraw the housing subassembly, install a new boot band and then hold the joint boot assembly on the halfshaft.
  16.  
  17. Install the spider assembly securely, making sure that the matchmarks are aligned. Make sure that when press fitting the assembly, the serration chamfer faces the shaft.
  18.  
  19. Stake the serration sides evenly at three places, avoiding areas that have been previously staked. Always stake two or three teeth in an area where the staked gap is more than 0.1mm.
  20.  
  21. Pack with grease.
  22.  
  23. Install the greased O-ring to the housing assembly and then place the hold joint boot assembly so that its flange is in the vise. Be sure that no other part of the assembly is in the vise.
  24.
