vibration
i have a nasty shake only at 40-50 mph. its the motor which is a 7.3 cause i get up to this speed then throw it in neutral and turn off the motor still there till under 30 i had the front end checked and tires rotated and balanced still there. my guess is drivshaft or carrier bearing. any ideas guys its 2002 crew cab 4x4 7.3L with 70000 miles

I agree. It sounds like a u-joint or driveshaft center support bearing. Ford also has a TSB on the subject.
TSB 04-22-7
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 use1. 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.
