Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Remove the Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel fasteners with a socket set and take the wheel off.

3. Remove the Strut Assembly

Detach the brake line and any sensors connected to the strut using appropriate tools.
Remove the nuts from the top strut mount located in the engine compartment (may require removing the engine cover).
Remove the bolts securing the strut to the lower control arm.
Carefully pull the strut assembly out of the wheel well.

4. Inspect and Replace Parts

Inspect the strut for damage; if leaking, it must be replaced.
If strut mounts or bushings show wear, replace them as well.
Install the new strut assembly, ensuring it is properly aligned.

5. Reassemble

Reattach the strut to the lower control arm and secure it with bolts, tightening to manufacturer specifications (check torque values in the service manual).
Reconnect the brake line and any sensors removed earlier.
Reinstall the top strut mount nuts and tighten them.
Replace the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Final Checks

Lower the vehicle and fully tighten the wheel lug nuts in a crisscross pattern to the specified torque.
Reconnect the battery.
