Driveline Application: Center support bearing for two-piece propeller shaft

Professional installation recommended. Proper driveline service is critical:

1. Raise and secure the vehicle - Safely raise the vehicle and support on jack stands
2. Mark the drive shaft - Mark the drive shaft orientation to maintain factory balance
3. Remove the drive shaft - Unbolt and remove the propeller shaft from the vehicle
4. Remove the old center bearing - Unbolt and remove the center bearing assembly from the chassis crossmember
5. Inspect the drive shaft - Check the drive shaft tube and yokes for damage or wear
6. Inspect U-joints - Check U-joints for wear, play, or damage; replace if necessary
7. Inspect rubber cushion - Check the rubber mounting cushion for cracks or deterioration
8. Clean mounting area - Clean the crossmember mounting surface and surrounding area
9. Prepare the new bearing - Inspect the new bearing and verify it matches the original
10. Install the new bearing - Position the new bearing on the drive shaft and secure
11. Install the assembly - Position the drive shaft assembly and secure the bearing to the crossmember
12. Torque to specification - Tighten mounting bolts to manufacturer specification
13. Reinstall the drive shaft - Reconnect the drive shaft to the transmission and rear axle
14. Check alignment - Verify proper driveline alignment
15. Lower the vehicle - Lower the vehicle to the ground
16. Test drive - Test drive the vehicle to verify smooth, vibration-free operation
