Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which struts or shocks need replacement.
Secure the vehicle with jack stands for safety.

3. Remove the Old Struts/Shocks

Front Struts:
- Remove the wheel by loosening the lug nuts with a socket set.
- Disconnect the brake line from the strut if applicable.
- Unbolt the strut from the steering knuckle and any upper mounting points (usually under the hood) using a socket wrench.
Rear Shocks:
- Remove the wheel.
- Unbolt the bottom of the shock from the rear axle and the top from the shock tower using appropriate sockets.

4. Install New Struts/Shocks

Front Struts:
- Position the new strut in place and bolt it to the upper mount and steering knuckle, ensuring that all bolts are tightened to the manufacturer's torque specifications.
- Reconnect the brake line if it was disconnected.
Rear Shocks:
- Position the new shock in place and bolt it to the bottom and top mounts, ensuring proper alignment.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications.
Recheck all connections and ensure everything is secure.
