Center Bearing

Print

A fully sealed ball type bearing provides support to the two-piece propeller shaft in the center of the vehicle. The bearing is housed n a rubber dampened insulator ring that allows the bearing some (minimal) movement. Once the bearing has been pressed out of insulator, the bearing must be replaced because the seal is damaged upon removal.

REMOVAL & INSTALLATION



Special tools which may be necessary for the repair procedure:



J 22912-01 Rear Pinion Bearing Remover
 
J 42099 Center Bearing Installer
 

  1. Remove the propeller shaft.
  2.  
  3. Remove the propeller shaft slip yolk bootstrap and remove the boot.
  4.  


NOTE
Marking the propeller shaft must be performed to ensure correct spline alignment, as well as, retaining the production balance of the propeller shaft assembly.

  1. Mark the halves of the propeller shaft near the slip joint.
  2.  
  3. Separate the propeller shaft halves.
  4.  
  5. Remove the front propeller shaft bearing retaining ring from the journal.
  6.  
  7. Remove the slinger.
  8.  
  9. Remove the bracket bolts, and washers; remove the bracket from the insulator.
  10.  


NOTE
During the next step, only tighten the tool (J 22912-01) enough so that the tool supports the inner race and does to clamp onto the journal. Damage to the journal will occur.

  1. Install the J 22912-01 onto the shaft
  2.  
  3. Support the tool in a vice.
  4.  
  5. Drive the propeller shaft from the bearing using a deadblow hammer.
  6.  
  7. Remove the rear slinger.
  8.  

To install:

  1. Install the rear slinger.
  2.  
  3. Using tool J 42099, install the bearing onto the journal.
  4.  
  5. Install the bracket to the insulator.
  6.  
  7. Tighten the bolts to 16 ft. lbs. (22 Nm).
  8.  
  9. Install the slinger. Install the retaining ring.
  10.  
  11. Install the slip yolk boot onto the propeller shaft.
  12.  
  13. Clean the slip yolk journal mating surfaces.
  14.  
  15. Lubricate the slip yolk journal splines with grease, GM P/N 12345740, or equivalent.
  16.  


NOTE
When reassembling the propeller shaft halves, align both markings previously made, as well as the blind spline of the journal. If the propeller shaft halves are aligned properly, they should join with little effort. Do not force the halves together.

  1. Join the propeller shaft halves.
  2.  
  3. Install the slip yolk bootstrap.
  4.  
  5. Install the propeller shaft.
  6.
