Solution

1. Preparation

Tools Required: Socket set, wrench set, jack, jack stands, strut spring compressor, torque wrench, screwdriver, and safety goggles.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for added safety.
Disconnect the battery to ensure electrical safety while working with the struts.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle depending on which struts are being replaced.
Secure the vehicle with jack stands to ensure it is stable while you work.

3. Remove the Wheel

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

4. Detach the Strut Assembly

Front Struts:
1. Remove the bolts securing the strut to the steering knuckle (usually two bolts).
2. Remove the upper strut mounting nuts from the engine bay (typically three nuts on top).
Rear Struts:
1. Remove the bolts securing the bottom of the strut to the trailing arm.
2. Remove the upper strut mounting nuts from inside the trunk (access may require removing trim).

5. Compress the Spring

Using a strut spring compressor, carefully compress the spring on the strut assembly to relieve tension. Ensure equal compression on both sides for safety.

6. Replace the Strut

Remove the old strut from the spring and replace it with the new strut.
Reassemble the spring onto the new strut assembly and carefully release the spring compressor.

7. Reinstall the Strut Assembly

Position the new strut assembly back into the vehicle.
Secure the upper mount with the nuts and torque to the manufacturer's specifications.
Reattach the strut to the steering knuckle or trailing arm, ensuring all bolts are torqued correctly.

8. Reinstall the Wheel

Put the wheel back on and hand-tighten the lug nuts.

9. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.

10. Final Tightening

Once the vehicle is on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque value.
