  Q: How Should One Service and Repair the Air Suspension Air Spring to Ensure Safety and Proper Installation on Mercury Grand Marquis?

  A: Touching the air spring requires checking for total pressure elimination to eliminate risks of damage to the vehicle and personnel injury. A breach of the air compressor system air line will create unpredictable high-pressure air releases which produces threats to personnel safety and equipment destruction. Installation or inflation of damaged and unfolded rear air springs must be prevented because refolding these items precedes any installation and dealers should replace found air springs with improper folds during inspections. It is essential to not add air to an air spring which descended from the rebound hanging stage into the jounce stop position. The installation of a replacement air spring should never receive suspension loading before the air springs reach their required inflation level. Check the shape of the air spring after it receives air pressure. You need to lift the vehicle on a sufficient device while switching off the air suspension button which exists on the left side of the luggage compartment before starting any air suspension deflation procedure. First elevate the vehicle for support after which you should eliminate the rear air spring retainer to remove the bottom of the spring from contacting the rear axle. The electrical connector needs removal after which a push on the red air line retaining ring will release the air line so that you can remove the air spring. Before inflation of the air spring installation must proceed without any compression of the suspension. Place the air spring assembly into its frame seat before adding the retainer clip and position the bottom of the air spring onto the rear axle. Complete insertion of the white air line into its fitting must be verified before final connection. Hook up the air spring solenoid valve by joining electrical wires with air lines but keep the air spring properly shaped with no wrinkles and refill its pressure.
