The problem
THE PREFABRICATED PINCH BOLT CLAMP AT THE LOWER STEERING SHAFT LOWER YOKE MAY NOT PERFORM ADEQUATELY WHEN TIGHTENED TO SPECIFICATIONS. THE CLAMP MAY THEN DEFORM AND LOSS OF CLAMPING FORCE AND STEERING SHAFT DISENGAGEMENT MAY RESULT.
What owners should do
DEALER WILL RETROFIT WITH LOWER STEERING SHAFT LOWER YOKES THAT PROVIDE FOR INTEGRAL PINCH BOLT INSTALLATION IN PLACE OF PREVIOUS SEPARATELY FABRICATED CLAMP FOR THE PINCH BOLT.
