0 SK-4085 Arnott Front Right Shock BMW X3/X4 (F25/F26 Chassis), with VDC, RWD, and AWD 200

Coil Strut Removal

1 Raise the vehicle and remove the front wheel to expose the front coil strut. (Figure 1)

2 Disconnect the acceleration sensor from the bracket on the coil strut. (Figure 2)

3 Disconnect the coil sensor from the coil strut. (Figures 3, 4)

4 Disconnect the sway bar link and the brake hose from the strut tab. (Figures 5, 6, 7)

5 Remove the strut pinch bolt securing the strut to the wheel hub carrier. (Figure 8)

6 Tap the wheel hub carrier slightly with a hammer to separate the strut from the wheel hub carrier. (Figures 9, 10)

7 Remove the bolt from the strut bar. (Figures 11, 12)

8 Remove the three (3) top bolts from the top strut mount. (Figures 13, 14)

9 Remove the coil strut assembly from the vehicle. (Figure 15)

10 Removal complete.

Coil Strut Disassembly

Use a spring compressor tool for the following removal steps.

1 Remove the bolt and the acceleration sensor from the old strut. Then, mount it to the new strut. (Figures 16, 17, 18)

2 Put the coil strut assembly into the coil compressor tool to loosen tension on the top mount. (Figures 19, 20)

3 Remove the lock nut from the top of the strut to remove the top mount. (Figures 21, 22)

4 Remove the strut from the coil spring. (Figure 23)

5 Remove the top mount, bump stop, and rubber spring isolator from the old strut for reuse on the new strut. Discard the old top lock nut. (Figure 24)

6 Coil strut disassembly complete.

Coil Strut Reassembly

Tighten all nuts and bolts to the manufacturer's specifications during the assembly process.

1 Install the rubber spring isolator from the previous strut and align the rubber point with the respective hole on the spring seat. (Figures 25, 26)

2 Install the bump stop and dust cover from the old strut on the new strut. (Figure 27)

3 Remove the top lock nut from the new Arnott strut to be used later. (Figure 28)

4 Add the new strut to the coil spring in the spring compressor tool. (Figure 29)

5 Mount the old top mount on the new strut by using the new top lock nut and tighten to the manufacturer's specifications. (Figures 30, 31, 32)

6 Align the lower coil winding with the rubber spring isolator before releasing tension from the coil spring. (Figure 33)

7 Now use the compressor tool to release tension from the coil spring, making sure the lower coil winding is properly seated in the rubber isolator. (Figures 34, 35)

8 Push the bump stop and dust cover back into the top mount. (Figures 36, 37)

9 Coil strut reassembly complete.

Coil Strut Installation

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

1 Place the assembled Arnott coil strut into the vehicle. (Figure 38)

2 Align the top mount to the holes in the strut tower. (Figure 39)

3 Reinstall the 3 top bolts on the top strut mount to the strut tower and tighten to the manufacturer's specifications. (Figure 40)

4 Connect the strut bar by reinstalling the bolt to the strut's top mount. (Figure 41)

5 Align the locating pin to the center of the wheel hub carrier. (Figure 42) Make sure that it is fully mounted into the strut seat of the wheel hub carrier. (Figures 43, 44)

6 Remount the lower bolt that secures the strut to the wheel hub carrier. Ensure that the wire bracket is securely seated. (Figure 45) Use a torque wrench to tighten the lower bolt. (Figure 46)

7 Reconnect the sway bar link and the brake hose, and reinstall and tighten the nut. (Figure 47)

8 Reconnect the coil sensor. (Figures 48, 49)

9 Reconnect the acceleration sensor. (Figure 50)

10 Installation complete.

A wheel alignment is strongly recommended after installation.
