The center bearing is a sealed unit which must be replaced as an assembly if defective.


WARNING
It is extremely important to matchmark the driveshaft components to their mating surfaces, prior to disassembly. Failure to due so may result in a severe vibration problem, due to the misalignment of the driveline components.

  1. Remove the driveshaft.
  2.  
  3. Paint a matchmark across where the flanges behind the center yoke are joined. This is for assembly purposes. If you don't paint or somehow mark the relationship between the 2 shafts, they may be out of balance when you put them back together.
  4.  
  5. Remove he bolts and separate the shafts. Make a matchmark on the front driveshaft half which lines up with the mark on the flange half.
  6.  
  7. Hold the driveshaft using special tool ST38060002 or equivalent, while unbolting the companion flange from the front driveshaft. Do not place the front driveshaft tube in a vise. The best way is to grip the flange while loosening the nut. It is going to require some strength to remove.
  8.  
  9. Press the companion flange off the front driveshaft and press the center bearing from its mount.
  10.  

To install:
  1. The new bearing is already lubricated. Install it into the mount, making sure that the seals and so on are facing the same way as when removed.
  2.  
  3. Slide the companion flange, onto the front driveshaft, aligning the marks made during removal. Install the washer and locknut. If the washer and locknut are separate pieces, tighten them to 145-175 ft. lbs. (197-238 Nm). If they are a unit, tighten it to 180-217 ft. lbs. (245-295 Nm). Check that the bearing rotates freely around the driveshaft. Stake the nut.
  4.  
  5. Connect the companion flange to the other half of the driveshaft, aligning the marks made during removal. Tighten the bolts securely.
  6.  
  7. Install the driveshaft.
