Hazard Alert Messages
Read and observe all Warning and Caution hazard alert messages in
this publication. They provide information that can help prevent
serious personal injury, damage to components, or both.
To prevent serious eye injury, always wear safe eye protection
when you perform vehicle maintenance or service.
Park the vehicle on a level surface. Block the wheels to
prevent the vehicle from moving. Support the vehicle with
safety stands. Do not work under a vehicle supported only by
jacks. Jacks can slip and fall over. Serious personal injury and
damage to components can result.
Tighten fasteners to the correct torque specifications. Do not
over-tighten or under-tighten fasteners, which can cause the
wheels to separate from the vehicle. Serious personal injury
and damage to components can result.
Assembly

mallet to install the seal.

that the seal inner diameter and the inner bearing turn freely
to prevent damage to components.
