Just a quick question-
I have this vibration between 45-55mph at the gas(diesel) pedal and seems to be right under the floor as well? I am taking it to see how the alignment is but is there anyone who has had the same symptoms? Thanks in advance.

I had a vibration between 70-78. It was the rear universal joint.

 

JMACC did you ever find out what that vibration was?

 

Actually- no I still haven't found the culprit. I am assuming its a u-joint,I had the front end checked and its right on the money. Next step could be to have the wheels and tires rebalanced? But with the christmas season upon us time is limited, so after the holiday u-joints will be the order of the day(all of them).
With 134,000 miles its probably a good idea.Thanks for the reply and I'll post when the joints are done to see if it makes a diff.

What year and model?

 

Its a 2000 CC Lariat 4x4 with an 8' bed and of course a PSD.

 

I have a 2002 CC 8' bed PS SD and I have been fighting a vibration for about the last 30K miles. It has 70K now and I can't find it. The vibration is in the foot pedal and also in the steering wheel and seat.. I have done the wheel thing and the dealer even changed out the torque convertor. If you come up with any thing I would be interested.

 

FYI - This may apply to your vibration.

FORD: 1999-2005 F-Super Duty


ISSUE:
Some 1999-2005 Super Duty F-Series 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 inch 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 3 threads past the nut. Use Motorcraft Threadlock 262 (TA-26), 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.



Before beginning the repair, road test the vehicle to gain a feel for the harshness of the shudder/vibration.
Install one (1) shim, (DO NOT use Threadlock on the bolts at this point), re-road test vehicle.
If condition is corrected, apply Threadlock and torque bolts as directed above. Return the vehicle to the customer.
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.
