Application

All Ford/Lincoln/Mercury vehicles so equipped



Tools You Will Need

1 ¾” cap screw (part OEM-723-3018) Diagnosis

Usual Symptoms (complaints)

1. Springs keep losing air.
2. Low ride height.
3. No ride height.
4. Suspension will not raise up.

Location and Usual Operation

1. There is only a single Height Sensor for the air suspension.
2. The Sensor is located above the rear axle housing attached to the car body and one of the axle locating arms.
3. There is a single, gray two wire electrical connector attaching it to the system.
4. The Height Sensor provides information to the suspension module based on the variance in actual length of the sensor from end to end depending upon the load in the vehicle.
5. When the vehicle is loaded, the body ground clearance decreases and thereby decreases the overall length of the Sensor.

Diagnosis

1. Diagnosis is visual.
2. The Sensor will be disconnected from the ball mount.

Disassembly

Verify Disconnection

1. Turn off air suspension switch in the trunk.
2. Raise necessary area of vehicle. (Usually Driver side rear)
3. Position Safety stands as needed.
4. Locate the sensor and confirm dislocation.

Removal from Vehicle

1. Pull top clip toward bottom of the sensor while wiggling it off the upper ball joint.
2. Disconnect the electrical connector.
3. Remove the sensor.
4. Remove the lower clip from the sensor.

Modifications

1. Start by drilling out the old ball joint pivot on the lower mounting bracket.
   



2. Next drill out the bottom socket of the sensor itself. You can not use the original socket opening because it is at a right angle to the new joint. NOTE: THE SENSOR JOINTS ARE FIXED!! THE BODY OF THE SENSOR DOES NOT ROTATE!!!
   
   
   
3. Use a Dremel or file to remove the plastic ‘bump’ above the drill site.

Assembly

1. Assemble the parts as pictured using flat washers and also using a lock washer under the nut. DO NOT USE LOCKWASHERS ON THE CAP SCREW!!! I switched to a 1 ¾” cap screw because it bottomed out in the joint before it could crush the plastic sensor socket. Check the clearance before assembly. You may need some BB’s under the cap screw to space it out far enough.
   
   
   
2. Install the assembly back on the car in the same position it was removed.
   
   
   
3. Lower car to ground.
4. Turn on the air suspension switch.
5. Recheck the car height.
6. Adjust as needed.

This has been operational on my 95 for about 8 months now, without any problems. Total cost was less than $20. Parts were obtained from my local lawnmower repair shop. And, you get 2 in the package!! Good thing 'cause the one on my riding lawnmower fell off the next day after I did the modification on the car . . . .
