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.
Use a brass or synthetic mallet for assembly and disassembly
procedures. Do not hit steel parts with a steel hammer. Pieces
of a part can break off. Serious personal injury and damage to
components can result.

fastener with a wrench. Do not use an impact wrench or hit the
fastener with a hammer.
2. Repeat Step 1 until you can remove the fastener.
