1 Locate the air suspension switch on the right side of the luggage compartment.

2 Turn the air suspension switch to the "OFF" position. (Figure 1)

6 Remove the clip that secures the top of the air spring to the chassis. (Figure 2)

To access the clip, go under the wheel arch, between the body of the vehicle and the chassis.

7 Disconnect the electrical connector. (Figures 3, 4)

8 Use pliers or a suitable hooked tool to remove the air spring solenoid retaining clip. (Figures 5, 6)

9 Rotate the solenoid counterclockwise to the first stop. (Figures 7, 8)

Slightly wiggle the solenoid as you rotate and pull it out.

10 Carefully and slowly pull the solenoid straight out to vent the air pressure from the air spring. (Figures 9, 10)

11 Once the air spring is fully deflated, slightly rotate counterclockwise again to align the tab with the opening and remove the solenoid from the air spring. (Figures 11, 12)

12 Remove the piston-to-axle spring seat clip. (Air spring is held in place with a round retainer clip under the piston cap. To unsnap the clip, gently pry between the piston and the axle. The clip will unsnap when pressure is applied). (Figure 13)

Failure to change O-rings on the solenoid can cause the air spring to leak, damage the compressor, and/or void the warranty.

To remove the air line: depress the orange collet top while pulling out on the air line.

2 Grip the top of the brass collet and remove it from the solenoid. Be very careful not to bend or distort the collet. (Figure 15)

3 Remove the nylon washer and small O-ring. (Figures 16, 17)

4 Remove the two (2) O-rings from the O-ring groove by first pinching the o-ring forward to create a lip (Figure 18). One at a time, stretch the O-rings out of the groove and off of the solenoid. (Figures 19, 20). Then, remove the large O-ring (Figure 21).

Be very careful not to damage sealing surfaces and avoid using tools that could do so.

1 Place the new small O-ring into the solenoid (Figure 22). Use a solenoid installation tool or use extreme caution to avoid scratches or damage. Be sure that the O-ring is seated properly and lying flat inside the solenoid (Figure 23).

2 Reinstall the nylon washer. (Figure 24) Inspect for scratches and replace as needed.

Before installation inspect the nylon washer for scratches and replace as needed.

3 Insert the brass collet back into the solenoid. You will need to compress the bottom of the collet while you press it back into the opening. Be very careful not to bend or distort the collet. (Figures 25, 26)

4 Once the collet is reinserted, press the orange collar top back over the top of the collet, making sure it snaps back into place. (Figure 27)

5 Roll the first O-ring over the tip of the solenoid and into the first O-ring groove. Do the same for the second O-ring, stretching over the first O-ring already seated, and place it into the second O-ring groove. (Figures 28, 29)

Apply an appropriate lubricant to O-rings to ease installation.

6 Place the large O-ring on the solenoid. (Figure 30)

1 After installing new O-rings, generously apply a non-petroleum lubricant such as silicone, lithium, or dielectric grease to the tip of the solenoid. (Figure 32)

2 Put the air spring on a table on its side or between your feet while sitting in a chair for better leverage as you install the solenoid. (Figure 33)

3 Align the appropriate solenoid tab at the opening. Push inward and clockwise to the first stop, and then to the second stop. Push in with force. (Figures 34, 35)

4 Ensure the solenoid is fully locked in place before beginning installation of the air spring onto the vehicle. (Figure 36)

5 Reinstall the solenoid retaining clip. (Figure 37)

Tighten all nuts and bolts to the manufacturer’s specifications during the installation process.

1 Once the O-rings are replaced and the solenoid and solenoid retaining clip are installed, position the air spring into the vehicle. (Figure 38)

2 Reinstall the clip that secures the top of the air spring to the chassis. (Figure 39)

3 Clip the bottom of the air spring piston to the axle. (Figures 40, 41)

It is very important to make sure the piston is clipped in and secure before inflating or pressurizing the air spring.

5 Reinstall the air line by pushing it into the solenoid fitting until you feel it pass through the internal O-ring and hit the internal stop. Gently tug the air line (without pressing the release collar) to verify it is securely locked into place.

Scratches and/or deep cuts in the air line may result in leaks. Inspect the air line before insertion. Replace the air line if damaged.

9 Turn the air suspension switch back to the "ON" position, and start the vehicle. The vehicle should rise back to factory trim height.
