  Q: What Are the Crucial Steps to Follow When Servicing Front Air Suspension to Prevent Damage or Personal Injury on Ford Crown Victoria?

  A:

  Air spring servicing requires staff to check all pressure has leaked from the air spring which avoids vehicle damage and ensures safety of personnel during the process. High-pressure air will vent uncontrollably when an air line connected to the air compressor is disconnected thus posing a risk to safety. Before installation you must refold unfolded rear air springs although this process works only for air springs which have not supported vehicle weight while improperly folded. The salesperson must replace any air springs displaying improper folding which appears either during pre-delivery checks or after delivery. Inflate any air spring only when it returns to the jounce stop from the rebound hanging position. Establish a method for air spring inflation and maintain constant observation of the conformed air spring shape throughout the inflation process. New air springs must have no applied vehicle load while undergoing the inflation procedure. The air suspension system deflation requires the vehicle to sit on a suitable lifting device followed by disconnecting power through the air suspension switch positioned on the LH side of the luggage compartment. To perform this installation workers must elevate the vehicle then remove the air spring retainer before lifting off the bottom air spring from the rear axle structure and detach both the electrical connector and air line by pressing the red retaining ring on the white air line. The installation process requires not compressing the suspension system before air spring inflation. Proceed by putting the air spring assembly into the frame seat and then fasten the spring retainer clip while resting the bottom section of the air spring onto the rear axle. Connect the air spring solenoid valve by fully inserting the white air line into the fitting then reattach electrical connections followed by air line attachment. Make sure to check that the air spring maintains its correct shape without any folds or creases prior to filling the air springs.

  Q: How to Safely Service and Repair the Air Suspension on Ford Crown Victoria?

  A:

  The first step before service or repair is to check for air pressure absence in the air spring since operating with pressure presents a risk for vehicle damage and personal injury. Supporting the air spring remains essential while you remove any attached components from it. Do not clamp any area on the air spring piston. Set the air spring on a flat working area for service operations. The next step requires removing the air spring solenoid to enable expansion of the compressed Air Bag. You should position the membrane on top of the piston before adjusting its height to the desired measurement then reinstall the solenoid to retain this level.
