2 Deflate and disable the air suspension system according to the manufacturer’s specifications.

3 Remove the rear wheel and fender liner. (Figure 1)

4 Disconnect the electrical connector, first disengaging the locking tab by pulling it downward. (Figures 2, 3)

5 Unscrew the air line fitting. (Figures 4, 5)

6 Remove the nut connecting the ride height sensor to the trailing arm. Move the ride height sensor out of the way to avoid damage. (Figure 6)

7 Remove the two control arm bolts. (Figures 7, 8)

Use an appropriate jack to support the wheel hub.

8 Remove the bolt connecting the clevis to the trailing arm. (Figure 9)

9 Remove the bolt connecting the trailing arm to the spindle. (Figure 10)

10 Free the trailing arm from the clevis and spindle by carefully pushing down on the trailing arm and up on the spindle. (Figures 11, 12)

11 Remove the bolt securing the strut to the clevis. (Figures 13, 14)

12 Use a wedge tool to separate the clevis and remove it from the strut. Leave the wedge tool in the clevis for easier installation. (Figures 15, 16)

13 Remove the three upper mounting bolts. (Figures 17, 18)

14 Remove the strut from the vehicle. (Figure 19)

1 Remove the alignment guide from the top of the OE strut.

2 On the new Arnott strut, unclip the electrical connector from the bracket. (Figure 20)

3 Install the guide onto the new Arnott strut, ensuring the wire guide is sitting in the dedicated space. (Figures 21, 22)

4 Route the electrical wire into the wire guide. (Figures 23, 24)

5 Reclip the electrical connector to the bracket.

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

1 Place the strut into the vehicle, lining up the alignment guide appropriately. (Figures 25, 26)

2 Loosely install the three upper mounting bolts. Do not tighten yet. (Figure 27)

3 Install the clevis onto the strut, ensuring that the base of the strut is fully seated. Do not install the bolt yet. (Figure 28)

4 Push down on the spindle and up on the trailing arm to realign the lower clevis and spindle to the trailing arm. Reinstall the trailing arm to clevis and spindle bolts but do not fully tighten yet. (Figures 29, 30)

5 Reinstall the two control arm bolts. (Figures 31, 32)

To avoid cross threading, first thread by hand and do not use impact tools.

6 Reinstall the bolt that secures the clevis to the strut. (Figure 33)

7 Reinstall the nut to connect the ride height sensor to the trailing arm. (Figure 34)

8 Remove the OE fitting from the air line. (Figure 35)

9 Remove the shipping pin and install the air line. (Figures 36, 37)

10 Plug in the electrical connector, ensuring the locking tab is engaged. (Figure 38)

11 Torque all nuts and bolts to the manufacturer’s specifications. (Figure 39)

12 Reinstall the rear wheel and fender liner.

13 Inflate and enable the air suspension system according to the manufacturer’s specifications.
