Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is on a level surface and safely raise it using jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Sub-steps:
1. Loosen the lug nuts on the wheel where the strut is located.
2. Use a jack to lift the vehicle and secure it on jack stands.
3. Remove the lug nuts and take off the wheel.

3. Disassemble Strut Assembly

Tools Required: Socket set, torque wrench, strut spring compressor
Sub-steps:
1. Remove the bolts securing the strut to the lower control arm and any other attachments.
2. Take out the bolts securing the strut mount at the top of the strut tower.
3. Use a strut spring compressor to safely compress the spring and remove it from the strut assembly.

4. Replace the Strut

Tools Required: Torque wrench, impact wrench (if available)
Sub-steps:
1. Install the new strut by reversing the disassembly steps.
2. Ensure the strut mount is securely fastened to the strut tower.
3. Torque all bolts to the manufacturer specifications (typically found in the service manual).

5. Reassemble and Test

Tools Required: Torque wrench, socket set
Sub-steps:
1. Reattach the lower control arm to the new strut, ensuring all bolts are torqued to specification.
2. Reinstall the wheel and torque the lug nuts in a star pattern to the recommended torque.
3. Lower the vehicle and reconnect the negative battery terminal.
