The problem
OPERATION UNDER EXTREME CONDITIONS OF HIGH HUMIDITY, SALT AND DIRT CAN CAUSE RUSTING OF THE SPLINED SECTION OF THE UPPER STEERING SHAFT. THIS CAUSES INCREASED STRESSES BETWEEN THE STEERING COLUMN UNIVERSAL JOINT CONNECTION AND THE INPUT SHAFT OF THE STEERING GEAR. CONTINUED OPERATION UNDER THESE CONDITIONS COULD RESULT IN UNACCEPTABLE MOTION OF THE LINKAGES.
What owners should do
ALL AFFECTED VEHICLES WILL BE EQUIPPED WITH A GREASE FITTING ON THE SPLINED SECTION OF THE UPPER SIDE OF THE UNIVERSAL JOINT.
