CENTER BEARING SHIMMING
Drive-away shudder is the predominant symptom associated with driveline angles condition on vehicles with two-piece driveshafts. After eliminating
coupling shaft phasing as the possible cause, driveline angles should be measured and corrected. Drive-away shudder can usually be serviced by
shimming down the driveshaft center bearing bracket in 6.35-mm (1/4-inch) increments using shims EOTZ-4A209-A or equivalent until the drive-away
shudder is eliminated. Plate stock must be used to maintain proper preload compression of the rubber insulator.
1. Replace the existing bolts with the appropriate length 7/16-14 hex-head bolts.
2. Tighten bolts to 51-73 Nm (38-54 ft. lbs.).
3. Road test to verify resolution of condition.
If the drive-away shudder cannot be serviced by shimming down the driveshaft center bearing bracket, check driveline angle.
