The driver’s side axle shaft will need to be disconnected.

14 Remove the upper strut mount nuts and remove the strut from the vehicle. (Figures 15, 16)

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

1 Install the new coilover strut into the vehicle. Loosely thread on the upper strut mount nuts to retain the strut. (Figures 17, 18)

2 Push down on the lower control arm to slide the lower strut mount over the axle shaft. (Figure 19)

3 Use a jack or other appropriate equipment to raise the lower control arm and reconnect the spindle to the upper control arm. Tighten hardware to manufacturer’s specifications. (Figure 20)

4 Reinstall the lower strut mount bolt and nut. Tighten to manufacturer’s specifications. (Figures 21, 22)

5 Reinstall the brake caliper. Tighten all hardware to manufacturer’s specifications. (Figure 23)

6 Reinstall the wheel speed sensor. Tighten to manufacturer’s specifications. (Figures 24, 25)

7 Reconnect the sway bar to the strut Tighten to manufacturer’s specifications.

8 Reconnect the steering arm to the knuckle. Tighten to manufacturer’s specifications. (Figures 26, 27)

9 Tighten the upper strut mount nuts to manufacturer’s specifications. (Figure 28)

10 Seal off and secure the air line in a safe location.

12 Front coilover strut installation complete.

1 Ensure the vehicle is properly lifted according to the manufacturer’s instructions.

2 Ensure the air suspension is deflated and deactivated according to the manufacturer’s instructions.

4 Remove the air line from the air spring. Remove the air spring. (Figures 30, 31)

5 Remove the lower shock mount bolt. (Figures 32, 33)

6 Remove the wheel well liner. (Figure 34)

7 Remove the upper shock mount bolts and remove the shock. (Figures 35, 36)

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

1 Install the new shock into the vehicle. (Figure 37)

2 Install the upper shock mount bolts. Tighten to manufacturer’s specification. (Figure 38)

3 Install the lower shock mount bolt. Tighten to manufacturer’s specification. (Figures 39, 40)

4 Place the upper spring seat and isolator onto the top of the coil spring. Place the lower spring perch onto the bottom of the coil spring. (Figures 41, 42)

5 Using an appropriate spring compressor, compress the spring and install the spring assembly into the spring pocket. Be sure to keep the isolator properly aligned with the coil spring. (Figures 43, 44)

6 Seal off and secure the air line in a safe location.

Electronic Bypass Module (EBM) Installation

1 Locate the air suspension control module under the driver side seat and disconnect the two (2) harnesses. The harnesses will remain disconnected. (Figures 45, 46)

2 According to the table below, splice the EBM harness wires to the applicable control module harness wires using the four (4) supplied heat-shrink butt connectors. (Figures 51, 52)

Electronic Bypass Module FROM COLOR TO COLOR PIN # HARNESS CONNECTOR Black Black 21 C2 Red Pink / Lt. Green 14 Blue Yellow/Gray 2 C1 Green Yellow 1

3 Connect the EBM to the EBM harness. (Figures 49, 50)

4 Place the EBM in a suitable spot, away from friction or pinch points.

Do not plug the suspension control modules back in. They remain unplugged. There should be no suspension error lights present in the instrument cluster.
