When pulling out the axle shaft in the 200SX, do not destroy the differential carrier seal or the CV boot. Start with both jacking and lifting the rear of the car off the ground, then unbolting the spring stay. Remove the four flange bolts of the axle shaft on the wheel side and pull the axle shaft, grasped at the center only, out of the differential carrier using some pry bar. The installation process is the reverse of the removal process, beginning with the differential end and proceeding to the wheel end; the four flange bolts need to be tightened to the following torque setting by the engine type. Again, loosening the CV boots of the 240SX requires some protection; hence, try covering them with some cloth. Lift the back of the car up and secure it, loosen and remove the rear tire and its assembly, and unbolt the adjusting cap and Cotter pin on the wheel bearing locknut. Pull the parking brake handle inward and release the rear wheel locknut and separate the axle shaft from the differential side where the small flange bolts are fixed. Move the axle shaft at the center and pull it from the wheel hub through wrench or a prybar or wooden block with up mallet and lock nut for temporary basis. For installation, align the shaft on the wheel hub, assume the lock nut; make sure it does not harm oil seal or either end of the axle shaft. Toward the axle shaft, secure the differential and fasten the flange bolts tightening them to the required torques. Apply the parking brake before tightening the locknut, replace the lost or damaged cotter pin with a new one, the adjusting cap, then fit the rear wheel and tyre assembly before lowering the vehicle. That was when dealing with the 240SX axle shaft assembly replacement, clamp the axle shaft in a vise with soft jaws, pry off the plug from the wheel side, and also take off the plug seal, spring, the spring cap, and the boot bands although it is very important not to reuse the boot bands again. Scratch a matchmark on the spider assembly and the axle shaft before using a press to take out the spider assembly with support to the axle shaft. Extract the slide joint boot and boot bands, raise the joint end of the axle shaft with the differential facing up and, using a cutting tool, cut off the hold joint boot assembly to liberate the housing subassembly. Take off the housing ring, the boot band, the housing cover with the O-ring. Connect a new hold joint boot assembly that is accompanied by a housing ring an O-ring and housing cover and see that the O-ring has been greased. In the outline, this is but to hammer the edge of the housing cover with a mallet, fit a new boot band, and fasten the joint boot assembly to the axle shaft. Place the spider assembly properly, also make sure that match mark is aligned with the other one, then stake the serration sides properly, next step is to pack with grease and the last step is to install the greased O-ring in the housing assembly. Place the housing subassembly, fold the edge in the same way, apply a sealant on the boot and place the boot along with installing the boot bands. Swing the axle shaft round so that the wheel end is uppermost; it is easier that way to install the new boot bands, the joint boot, and the housing, without scratching them. Last to be fitted is the spider assembly, the large diameter boot band, pack with grease and secure the spring cap, spring, and plug seal before using a hammer to lock the plug and replace the axle shaft with the specified amount of grease for either side or both.
