Diagnostic Steps

Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, strut spring compressor, impact wrench, and safety goggles.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the 12V battery to prevent electrical shorts.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which struts are being replaced.
Place jack stands under the vehicle to ensure it is securely elevated.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the strut assembly.

4. Disconnect Strut Assembly

Front Strut:
- Remove the lower strut nut and bolt using an impact wrench.
- Disconnect the sway bar link from the strut.
- Remove the upper strut mount nuts located in the engine bay or under the dash (may require lifting the front trunk liner).
Rear Strut:
- Remove the lower strut nut and bolt from the control arm.
- Disconnect any associated components that may impede strut removal (such as brake lines).
- Remove the upper strut mount nuts from the trunk area.

5. Install New Struts

Use a strut spring compressor to compress the coil spring on the new strut assembly if necessary.
Position the new strut in place and secure the upper mount using the original nuts.
Reattach the lower strut bolt and torque it to the manufacturer specifications (typically around 60-80 ft-lbs for the lower strut bolt).
Reconnect the sway bar link (for front struts).

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer's specifications (usually around 100-120 ft-lbs).

7. Reconnect Battery

Reconnect the 12V battery and ensure the electrical systems are functioning properly.
