Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather tools and safety equipment (jack stands, wheel chocks).
Disconnect the battery if working on electronic components.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure the vehicle with jack stands for safety.

3. Remove the Struts

Front Struts:
1. Remove the wheel lug nuts using a socket set and take off the front wheels.
2. Disconnect the brake line bracket from the strut.
3. Remove the bolts securing the strut to the steering knuckle.
4. Unbolt the top strut mount under the hood.
5. Carefully remove the strut assembly from the vehicle.
Rear Struts:
1. Remove the rear wheels.
2. Unbolt the lower strut mounting bolts.
3. Remove any necessary components blocking access to the top strut mount.
4. Unbolt the top strut mount from inside the trunk.
5. Remove the rear strut assembly.

4. Inspect and Replace

Inspect the old struts for signs of wear, including any fluid leakage.
Compare with new struts to ensure correct specifications.
Install new struts by reversing the removal steps, ensuring all bolts are tightened to manufacturer specifications (refer to the repair manual for torque values).

5. Reassemble and Lower the Vehicle

Reattach the wheels and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then torque the lug nuts to the specified values.
Reconnect any components that were disconnected during the removal process.
