Hazard Alert Messages
Read and observe all hazard alert messages in this publication.
DANGER
Park the vehicle on a level surface. Block the wheels to prevent
the vehicle from moving. Support the vehicle with safety stands.
NEVER work under a vehicle supported only by jacks. Jacks can
slip and fall over. Failure to use a jack stand can result in serious
personal injury and damage to components.
DANGER
Only service a driveline when the engine is OFF. A rotating
driveline can cause serious personal injury.
WARNING
NEVER use a steel hammer to seat bearing cups into yoke
bores. A steel hammer can cause the yoke or bearing cup to
crack and break off. Serious personal injury and damage to the
trunnion, yoke or bearing cup can result.
WARNING
To prevent eye injury, always wear eye protection when
performing vehicle maintenance or service.
