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.

Note: Use Tooling (A) in order to raise the front axle until the wheels clear the ground. This will release the driveline torque windup in the front axle.
