Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the 12V battery to prevent electrical issues.
Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Strut spring compressor (if necessary)

2. Remove Strut Assembly

Lift the vehicle using a jack and support it securely with jack stands.
Remove the front wheels to access the strut assembly.
Detach the brake line bracket from the strut (if applicable).
Remove the lower strut bolts using a socket wrench.
Unscrew the top strut mount nuts from inside the engine bay or trunk area (depending on strut location).
Carefully remove the strut assembly from the vehicle.

3. Inspect and Replace Components

Inspect the strut for any oil leaks or physical damage.
Check the strut mounts for signs of wear; replace if necessary.
If using a strut with a coil spring, use a strut spring compressor to safely remove the coil spring from the strut.
Replace any worn components (strut, mount, or other parts).

4. Reinstall Strut Assembly

Position the new or inspected strut assembly back into the vehicle.
Secure the top mount with nuts and torque them to manufacturer specifications (check torque values in the service manual).
Reattach the lower strut bolts and torque to proper specifications.
Reconnect the brake line bracket.

5. Final Checks

Reinstall the front wheels and lower the vehicle.
Reconnect the battery.
Perform a visual inspection of the installation to ensure everything is secure.
