Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and floor jack.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use the floor jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Components

Sway Bar Links:
- Remove the nuts securing the sway bar links using a socket.
- Replace with new sway bar links if worn or damaged.
- Torque the nuts to the manufacturer’s specifications (typically around 40-50 ft-lbs).
Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Unbolt the strut from the knuckle and the top mount (refer to the service manual for exact steps).
- Replace with new struts if they show signs of leakage or wear.
- Reassemble and torque all bolts to the specified values.
Control Arms:
- Check the bushings for wear and replace if necessary.
- Unbolt the control arm from the chassis and knuckle.
- Install a new control arm, ensuring all bolts are torqued properly.

4. Reassemble

Reinstall the wheel and lower the vehicle.
Tighten the lug nuts to the manufacturer’s specification (typically around 80-100 ft-lbs).
