NOTE: Suspension fasteners are critical components because they affect performance of vital components and systems and their failure can result in major service expense. Install new components with the same component number or an equivalent component if installation is necessary. Do not use an installation component of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these components.

WARNING: Always secure transmission, transfer case, and axle assemblies to their service jack. Avoid obstructions while lowering and raising the jack. Improperly secured assemblies or contact with obstructions may cause the assembly to fall off the jack, which could result in serious personal injury.

Use a suitable transmission jack to support the axle.
