DISASSEMBLY

NOTICE: Suspension fasteners are critical parts that affect the performance of vital components and systems. Failure of these fasteners may result in major service expense. Use the same or equivalent parts if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Tighten fasteners as specified.

NOTE: Disassembly steps in this procedure may contain assembly details.

1. Remove the shock absorber and spring assembly.
   Refer to: Shock Absorber and Spring Assembly (204-01A Front Suspension - RWD, Removal and Installation).
   

1.   WARNING: Coil springs and strut assemblies are compressed under extreme load. Always use a spring compressor for disassembly. Follow procedure instructions carefully and make sure the spring compressor has the correct spring plates or adapters. Failure to follow these instructions may result in serious personal injury.

   NOTICE: When installing a suitable spring compressor, use care not to damage the spring coating.

   NOTICE: Take extra care not to damage the component.

   NOTICE: Do not use power tools to remove the nut.

   Compress the coil spring enough to relieve the tension on the strut assembly.
