Solution

1. Preparation

Gather tools and parts needed for the strut replacement.
Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel on the side where strut replacement is needed.

3. Remove the Old Strut

Disconnect any brake line brackets or sensors attached to the strut assembly.
Remove the lower strut mounting bolt using a socket set.
Use a wrench to remove the top strut nuts from the strut tower inside the engine compartment.

4. Install the New Strut

Position the new strut in place and secure it with the top nuts first.
Tighten the top nuts to the manufacturer's specified torque (usually around 20-30 ft-lbs, but check your service manual).
Reattach the lower mounting bolt and torque it to specifications.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Repeat the process for the other side if necessary.
Perform a test drive to ensure proper handling and comfort.
