CAUTION: Suspension fasteners are critical parts because they affect performance of vital
components and systems and their failure can result in major service expense. A new part with
the same part number or an equivalent part must be installed, if installation is necessary. Do
not use a part of lesser quality or substitute design. Torque values must be used as specified
during reassembly to ensure correct retention of these parts.
1. Raise the vehicle on a hoist. For additional information, refer to Section 100 - 02 .
2. Remove the wheel and tire assembly. For additional information, refer to Section 204 - 04 .
3. Remove the front wheel hub (1104). For additional information, refer to Wheel Hub and Bearing in this section.

CAUTION: Suspension fasteners are critical parts because they affect performance of vital
components and systems and their failure can result in major service expense. A new part with
the same part number must be installed if installation becomes necessary. If substitution is
necessary, the part must be of the same finish and property class. Torque values must be used
as specified during reassembly to make sure of correct retention of these parts.
1. Remove the rear wheel knuckle (5A968/5A969). For additional information, refer to Wheel Knuckle — Cobra in this section.
