ISSUE:
Lubricant leaking from the rear axle on F-250 and F-350 trucks, with Ford 10.25" full float axles may be caused by the hub seal. The
leaking condition could affect trucks with single or dual rear wheels.
ACTION:
To correct this, install a new design hub seal with improved sealing qualities. The new hub seal is "green" in color to assist in part
identification. Refer to the appropriate Light Truck Shop Manual, Volume A, Section 15-09 and the following service procedure for
removal and installation instructions.
