Precautions for Steering System

• Before disassembly, thoroughly clean the outside of the unit. 
• Disassembly should be done in a clean work area. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter. 
• Place disassembled parts in order, on a parts rack, for easier and proper assembly. 
• Use nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might interfere with their operation. 
• Before inspection or reassembly, carefully clean all parts with a general purpose, non-flammable solvent. 
• Before assembly, apply a coat of recommended power steering fluid ^*  to hydraulic parts. Vaseline may be applied to O-rings and seals. Do not use any grease. 
• Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during installation. Perform functional tests whenever designated.
