ISSUE:

Some 2006 F-250-F-550 Super-Duty vehicles built between 5/1/2005 - 9/30/2005 may exhibit a driveline vibration of 90-115 hertz (Hz) at speeds between 40-50 MPH (64-80 Km/h) caused by driveshaft universal joints (U-joints).
ACTION:

Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE



Test drive the vehicle using a vibration analyzer while the vibration is occurring. The most accurate readings can be obtained with the accelerometer placed on the seat track.
Record the frequency at which the vibration is occurring. If the frequency is between 90-115 Hz, speeds of 40-50 MPH (64-80 Km/h), continue with this procedure. If the frequency is outside of 90-115 Hz, speeds of 40-50 MPH (64-80 Km/h), do not continue with this procedure and perform normal vibration diagnostics using Workshop Manual (WSM), Section 205-00.Inspection Of The Rear Driveshaft U-joint Assembly



Disconnect/remove the rear driveshaft from vehicle following WSM, Section 205-01.
Inspect the U-joint assembly at each end of the rear driveshaft where present (transmission, transfer case, or axle).
Rotate the universal joint through both planes - it should rotate smoothly and with little effort.
Listen/feel if the joint binds during rotation.
Inspect the snap rings to ensure that they are fully seated in the groove.
If inspection of the universal joint yields any of the above concerns, then the joint assembly should be replaced with the appropriate U-joint kit.
Install the U-joint assembly per WSM, Section 205-01. The flange should only be replaced if damaged, or if the snap rings do not seat fully in the flange yoke groove.
If the U-joints do not exhibit tightness or binding, and the efforts are loose, reinstall rear driveshaft following WSM, Section 205-01 with new fasteners and perform normal diagnostics to determine the cause of the vibration using WSM, Section 205-00.

88mph doesn't pertain to this.
