Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the battery to prevent electrical issues during strut replacement.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Loosen the lug nuts on the front or rear wheel where the strut is being replaced.
Raise the vehicle using a jack and securely place jack stands under the vehicle.
Remove the lug nuts and take off the wheel.

3. Remove Strut Assembly

Tools Required: Socket set, torque wrench
Locate the strut mounting bolts at the top and bottom of the strut assembly.
Use the socket set to remove the lower strut bolts from the wheel hub.
Access the upper strut mounts under the hood and remove the nuts securing the strut to the body.
Carefully pull out the strut assembly from the vehicle.

4. Install New Struts

Tools Required: Torque wrench, new struts, strut mounting hardware
Position the new strut assembly into place.
Secure the top of the strut with the upper nuts and torque them to manufacturer specifications.
Attach the lower strut to the wheel hub and torque the bolts to the recommended specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specifications.
Reconnect the battery and perform a test drive to ensure proper installation and function.
