Removal

NOTICE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part number or equivalent part, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Jacking and Lifting Service and Repair.

2. NOTICE: Disconnect the Electronic Power Assist Steering (EPAS) steering gear power supply electrical connector or damage to the steering gear internal power relay may occur resulting in steering gear replacement.

NOTICE: The ignition must be off when disconnecting Electronic Power Assist Steering (EPAS) electrical connectors. Failure to follow this direction may lead to DTCs being set in the EPAS module that can not be cleared, and result in the need to install a new EPAS assembly.
