Fig. Fig. 4: Remove the center bearing bracket

These models use a driveshaft with three U-joints and a center support bearing. The driveshaft is balanced as an assembly.

  1. Raise and safely support the vehicle.
  2.  
  3. Matchmark the flanges on the driveshaft and differential so the driveshaft can be reinstalled in its original orientation; this will help maintain drive line balance.
  4.  
  5. Unbolt the rear flange and the center bearing bracket.
  6.  
  7. Withdraw the driveshaft from the transmission and pull the driveshaft down and back to remove.
  8.  
  9. Plug the transmission extension housing to prevent oil leakage.
  10.  

To install:
  1. Lubricate the sleeve yoke splines with clean engine oil prior to installation. Insert the driveshaft into the transmission and align the flange matchmarks.
  2.  
  3. Install the flange and the center bearing bolts.
  4.  
  5. On 200SX and 240SX, torque the center bearing support bracket bolts to 19-29 ft. lbs.
  6.  
  7. On 200SX with CA20E and VG30E engines, torque the flange bolts to 29-33 ft. lbs. (39-44 Nm) and on the 240SX torque to 29-33 ft. lbs. (39-44 Nm).

U-JOINT REPLACEMENT



Disassembly
  1. Mark the relationship of all components for reassembly.
  2.  
  3. Remove the snap-rings. On early units, the snap-rings are seated in the yokes. On later units, the snap-rings seat in the needle bearing races.
  4.  
  5. Tap the yoke with brass or rubber mallet to release one bearing cap. Be careful not to lose the needle rollers.
  6.  
  7. Remove the other bearing caps. Remove the U-joint spiders from the yokes.
  8.  

Inspection
  1. Spline backlash should not exceed 0.5mm.
  2.  
  3. Driveshaft run-out should not exceed 0.6mm.
  4.  
  5. On later model with snap-rings seated in the needle bearing races, different thickness of snap-rings are available for U-joint adjustment. Play should not exceed 0.02mm.
  6.  
  7. U-joint spiders must be replaced if their bearing journals are worn more than 0.15mm from their original diameter.
  8.  

Assembly
  1. Place the needle rollers in the races and hold them in place with grease.
  2.  
  3. Put the spider into place in its yokes.
  4.  
  5. Replace all seals.
  6.  
  7. Tap the races into position and secure them with snap-rings.

DRIVESHAFT VIBRATION



To check and correct an unbalanced driveshaft, proceed as follows:

  1. Remove the undercoating and other foreign material which could upset shaft balance. Roadtest the vehicle.
  2.  
  3. If vibration is noted, disconnect driveshaft at differential carrier companion flange, rotate companion flange 180° degrees and reconnect the driveshaft.
  4.  
  5. Roadtest the vehicle, if vibration still exists replace driveshaft assembly. Note that driveshaft should be free of dents or cracks and run-out should not exceed 0.6mm.
  6.
