Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.

2. Remove Wheels

Use a lug wrench to loosen and remove the lug nuts from the front or rear wheels.
Safely remove the wheels and set them aside.

3. Remove Old Struts

Front Struts:
1. Disconnect the sway bar link from the strut.
2. Remove the lower strut mounting bolts using a socket and ratchet.
3. Remove the upper strut mounting nuts from the strut tower under the hood.
4. Carefully pull the strut assembly out of the vehicle.
Rear Struts:
1. Remove the lower and upper mounting bolts on the rear strut.
2. Take out the strut assembly from the vehicle.

4. Install New Struts

Front Struts:
1. Position the new strut assembly into place and secure it at the upper mount.
2. Tighten the upper mounting nuts to the manufacturer’s torque specification (typically around 30-40 ft-lbs).
3. Reattach the lower strut mounting bolts and tighten to specification.
Rear Struts:
1. Position the new rear strut into place and secure it with the upper and lower mounting bolts.
2. Tighten all bolts to the manufacturer's torque specifications.

5. Reinstall Wheels and Lower Vehicle

Place the wheels back on the vehicle and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Fully tighten the lug nuts to the manufacturer’s torque specification (typically around 100-150 ft-lbs).

6. Final Check

Inspect all components to ensure proper installation.
Reconnect any removed sway bar links or other suspension components.
