Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface, set the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove the Wheel

Tools Required: Socket set, lug wrench
Loosen the lug nuts on the wheel associated with the strut (front or rear).
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Strut

Tools Required: Socket set, torque wrench, strut spring compressor
Locate the upper strut mounting bolts under the hood or in the trunk (depending on the strut location).
Remove the upper mounting bolts using a socket.
Underneath the vehicle, locate the lower strut mounting bolts and remove them.
Use a strut spring compressor to safely compress the coil spring if necessary, then remove the strut assembly from the vehicle.

4. Install the New Strut

Tools Required: Torque wrench, strut spring compressor
Place the new strut assembly into position.
Reinstall the lower mounting bolts and torque them to the manufacturer’s specifications.
Reattach the upper strut mounting bolts and torque them accordingly.
If applicable, ensure the coil spring is properly seated and decompressed.

5. Reassemble the Wheel

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then torque the lug nuts to the manufacturer’s specifications.

6. Final Checks

Reconnect the negative battery terminal.
Perform a visual inspection to ensure all components are securely fastened.
