Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, strut spring compressor, and a wrench set.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during the repair.

2. Lift the Vehicle

Use the jack to lift the vehicle at the designated lift points.
Secure the vehicle on jack stands to ensure stability.

3. Remove the Wheel

Using the socket set, remove the lug nuts and take off the wheel to access the strut assembly.

4. Disconnect the Strut

Locate and remove the bolts securing the strut to the steering knuckle using the wrench set.
Remove the top strut mount bolts accessible from the engine bay, while ensuring to support the strut with a jack or have an assistant hold it.

5. Remove the Old Strut

Carefully lower the strut from its position and remove it from the vehicle.
If equipped, use a strut spring compressor to safely disassemble the strut assembly and remove the spring from the old strut.

6. Install the New Strut

If the spring was removed, install it onto the new strut using the spring compressor. Ensure that it is seated correctly.
Install the new strut into the vehicle, securing it in place with the top mount bolts and lower bolts to the steering knuckle. Torque to manufacturer specifications.

7. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and then torque the lug nuts to the specified value.

8. Final Checks

Reconnect the battery and check for any error codes or warning lights.
Perform a visual inspection to ensure everything is installed correctly.
