Vibration/ noise concerns involving driveshaft vibration on the subject vehicles may be solved by replacing the standard two-piece driveshaft with a
one-piece graphite driveshaft using the procedure outlined below.
CAUTION: Never replace a two-piece driveline with a one-piece STEEL driveline as vehicle damage may result leaving vehicle inoperative.
1.
Remove the existing two-piece driveshaft from the vehicle.
2.
Remove the two-piece driveshaft center bearing support plate. Rivets are to be removed by chiseling off the heads. Drilling or the use of cutting
torch may result in damage to the crossmember.
NOTE:
The support plate must be removed to prevent interference with the new driveshaft.
3.
When installing the one-piece driveshaft, be sure that the yellow dots on the driveshaft and axle flange are aligned. If the yellow dot on the axle
flange is not visible, the vehicle will have to be test driven to determine the best orientation. Tighten U-bolt nuts to 8-15 ft.lbs. Nuts must be
retightened evenly and within the specified torque to prevent premature U-joint bearing failure.
4.
Test drive vehicle to confirm fix.
