Notes:

• The tie rod is mounted in the steering knuckle "upside down" in the pictures above.
• The wheeling bearing dust boot is not present
• The lower ball joint nut is missing
• The swaybar -> steering knuckle nut is not present
• The upper ball joint pinch bolt and nut are not present
• Grease is not present on the lower control arm steering stop or steering knuckle steering stop
  
• The tie rods and upper ball joint shown above are aftermarket napa chassis parts manufactured by the dana corporation. The blue dust boot is constructed of polyurethane and contains a lubricant pressure relief system.
  
• The lower control arm is from a 1998 police interceptor and utilizes the staked styled bushings manufactured by the lemforder corporation.
• The upper control arm is from a 2001 civilian grand marquis with the handling and performance package (HPP)
  
• The empty hole in front of the lower bump stop has not been used in any crown vic manufactured since 1992. In the pre-1992 vehicles, it was where the front stabilizer bar links attached though.
• The shock absorber pictured is marketed under the gabriel brand name. The top washer and nut do have some surface rust present on them, but a pneumatic impact wrench was able to seperate the two apart. The shock absorber unit had only been installed for around two summer months prior to being removed. And it had not been in contact with any winter chloride road salts when the pictures were taken.
  
• The brake rotor is from a production 2002 crown victoria lx sport and is 12.4" in diameter. The brake caliper bracket is the later style 1998+ one for the dual piston calipers.
• The suspension spring is "NUL" code one from a 1998 police interceptor
• The lower control arm is considerably longer than the upper one (SLA suspension). The upper control arm also integrates a strong anti-dive curvature.
  
• Electronic vehicle dynamics simulation software is avaliable in various software products including: Performance Trends Suspension Analyzer and MSC Adams.
