Publication Date: November 3, 2006

FORD:
1999-2007 F-Super Duty

This article supersedes TSB 05-17-6 to update the vehicle model years.

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.
    1. If condition is corrected, apply threadlock and torque bolts as directed above.
    2. 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.
