  Q: How to replace the Rear Ride Height Sensor on Cadillac STS?

  A:

  A correct replacement of the Electronic Suspension Rear Position Sensor demands that technicians both raise and support the vehicle. Remove the tire and wheel. Pull out the ride sensor link which connects the ball stud at the upper control arm and the ride sensor harness terminal. Remove the rear ride sensor by first loosening its retaining nut while using gentle taps on the rear ride sensor retaining stud to separate it from the frame connection. The sensor must be placed inside the vehicle while verifying that the fastener reaches its lowest position on the keyhole before rotating the sensor-bracket assembly until the bracket slot receives the entire tab. The sensor bracket needs rotation until it reaches proper level position. Connect the rear ride height sensor retaining nut with 9 N.m (80 lb in) torque value. The installation process includes joining the ride sensor harness connector to its dedicated pin on the controlling ball stud of the upper control arm. Attachment of the tire and wheel follows before lowering the vehicle.

  Q: How to replace the Ride Height Sensor and Bracket at the front on Cadillac STS?

  A:

  The first step to replace the Ride Height Sensor along with its Bracket at the front requires a vehicle lift for support followed by tire and wheel removal.

Pull out the front ride sensor component from the vehicle equipment. To install the sensor, mount it correctly while tightening the front ride sensor retaining nut to 9 Nm (80 inch lbs.) and follow the service precautions regarding fasteners. Install the front ride sensor link to the upper control arm ball stud followed by connecting the front ride sensor harness connector before putting back the tire along with wheel and letting the vehicle rest on the ground.
