DRIVE-AWAY SHUDDER OR VIBRATION
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. 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.

Yes, the center carrier bearing. Also I have seen the rear ends give trouble even taking off straight ahead. The way to usually take care of that is to change the fluid in the rear end and add 2 bottles of ford friction modifier.

Mine had dry U-joints. Sealed OEM w/ no zerts. Couldn't see anything wrong with them 'til they were apart, lots of spalling. :cool: JB

the friction modifier was mainly for clutch chatter on pull out and turns really wont help straight pull away.
Yea, thats what I was meaning but I have actually ran into the clutch pack chattering in a straight line taking off. Did a service and added ford friction modifier with fluid and cured the problem. Not really sure exactly why but it fixed it.

yea I agree it could work,when do you get a perfectly flat surface? Or are the tires always the same exact size? If the rear tires are not spining exactly the same amount the limited slip is always working.I have run into stranger shit that could not be explained.

Ran into this same problem with a 2006 Dodge 3500 last month. Got really bad with a loaded trailer behind it. Turned out to be the rear u-joint. I know you have replaced the joints, but I have installed alot of new parts that turned old quick.
