Removal and Installation

NOTICE: While repairing the power steering system, care should be taken to prevent the entry of contaminants or failure of the power steering components may result.

NOTICE: The steering gear bolts must not be reused. The threads of the bolts are coated with a dry adhesive. When the bolts are removed, the dry adhesive is degraded. If the bolts are reused, failure of the bolts and/or steering gear may occur.

NOTICE: Do not allow the steering column shaft to rotate while the intermediate shaft is disconnected or damage to the clockspring can result. If there is evidence that the shaft has rotated, the clockspring must be removed and recentered. For additional information, refer to Restraints and Safety Systems &/or Air Bag Systems.

NOTICE: The sector shaft arm-to-sector shaft nut must not be reused. The threads of the nut are coated with a dry adhesive. When the nut is removed, the dry adhesive is degraded. If the nut is reused, failure of the nut and/or sector shaft arm and shaft may occur.

NOTICE: New O-ring seals must be installed on the pressure and return line/hose fittings or a fluid leak may occur.
