Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove the Wheel

Tools Required: Socket set, ratchet, lug wrench
Loosen the lug nuts on the wheel corresponding to the strut being replaced.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove the Strut Assembly

Tools Required: Socket set, torque wrench, strut compressor
Remove the bolts securing the strut to the knuckle (usually at the bottom).
Remove the top strut mount nuts located in the engine bay or under the rear deck (depending on model).
Use a strut compressor to safely compress the coil spring if reusing the spring.
Carefully remove the strut assembly from the vehicle.

4. Replace the Strut

Tools Required: Socket set, torque wrench
Install the new strut into the strut mount and secure it using the top nuts. Torque to manufacturer specifications.
Reinstall the strut into the knuckle and secure it with the bolts. Torque to manufacturer specifications.

5. Reassemble the Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the specified value.
Reconnect the negative battery terminal.

6. Final Inspection

Check for any leaks around the new strut.
Ensure all bolts are tightened to the specified torque values.
Perform a test drive to ensure proper handling and performance.
