Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, stable surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, securing it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove the Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Remove the wheel to access the strut assembly.

4. Remove the Strut Assembly

Disconnect any brake line or ABS sensor wire attached to the strut.
Remove the bolts securing the strut to the knuckle using a socket set.
Remove the top strut mount bolts from the engine bay or under the dashboard, depending on the model.
Carefully take out the strut assembly from the vehicle.

5. Inspect and Replace

Inspect the strut for any physical damage; if damaged, replace with new struts.
Install new struts by reversing the removal steps, ensuring all bolts are tightened to the manufacturer’s torque specifications.

6. Reassemble

Reattach the wheel and tighten the lug nuts in a crisscross pattern.
Lower the vehicle back to the ground and reconnect the negative battery terminal.
