Personal injury or death can result from improper lifting or blocking. When a hoist or jack is used to lift any part or component, stand clear of the area. Be sure the hoist or jack has the correct capacity to lift a component. Install blocks or stands before performance of any work under a heavy component. Approximate weights of the components are shown. Clean all surfaces where parts are to be installed. |

Personal injury can result from driveline torque windup under load. Unequal wheel speed can result in driveline torque windup which can cause driveline components to be under load during disassembly. Relieve the driveline torque windup before disassembly. |
