ISSUE
Some 1999-2007 F-Super Duty vehicles may exhibit excessive drive-away shudder or vibration, under moderate to heavy acceleration from a stop. This
may be due to driveline angle.
ACTION
Shim the center carrier bracket downward to correct the condition. Refer to the following Service Procedure.
SERVICE PROCEDURE
When shimming the center carrier bracket, a maximum of three (3) 1/4" shims may be used (EOTZ-4A209-A). When refastening the carrier bracket use
bolt (56564-S2). A 7/16 x 14 grade 5 bolt may be substituted providing that it extends at least three (3) threads past the nut. Use Motorcraft®
Threadlock 262, and torque bolts to 46 lb-ft (62 N.m).
NOTE
IF THE VEHICLE IS NORMALLY LOADED, ROAD TESTS WILL NEED TO BE PERFORMED WITH THE VEHICLE LOADED.
1.
Before beginning the repair, road test the vehicle to gain a feel for the harshness of the shudder/vibration.
2.
Install one (1) shim, (DO NOT use threadlock on the bolts at this point), re-road test vehicle.
a.
If condition is corrected, apply threadlock and torque bolts as directed above.
b.
If condition is not corrected, re-perform step 2 (to a maximum of three (3) shims) and reevaluate vehicle.
NOTE
IF THE CONDITION IS STILL NOT CORRECTED AFTER INSTALLING A MAXIMUM OF THREE (3) SHIMS, REFER TO WORKSHOP
MANUAL SECTION 205-00 FOR FURTHER DIAGNOSTICS.
