Center Support: Service and Repair
Coupling Shaft/Center Bearing Alignment
Vehicle noise and vibration can be caused by dislocated or failed driveshaft center bearing support rubber insulator, contaminated driveshaft center
bearing support, or excessive compression of the rubber insulator.
The service for this condition is as follows:
1. Remove the coupling shaft from the vehicle.
2. Remove the driveshaft center bearing bracket and retainer.
3. Remove the rubber insulator.
4. Press driveshaft center bearing support and bearing retainer off the coupling shaft.
5. Press the dust slinger off the coupling shaft.
6. Replace with Center Bearing Assembly Kit E4TZ-4800-A.
7. Install driveshaft center bearing support in rubber insulator and press bearing on shaft with the turned-in lip toward the dust slinger (forward). The
support bracket must be installed with the deep flange rearward.
8. Reassemble the coupling shaft.
9. Reinstall the driveline in the vehicle with the yokes phased properly.
10. Road test to verify resolution of condition.
11. If vibration still exists, insert 1.59-mm (1/16-inch) shims between driveshaft center bearing bracket and support plate (on bolt ends of driveshaft
center bearing bracket) to reduce compression of the rubber insulator as required.
