Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, safety glasses
Ensure the vehicle is parked on a flat surface, and engage the parking brake.

2. Remove Wheel

Loosen lug nuts slightly while the wheel is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel by fully unscrewing the lug nuts and taking the wheel off.

3. Inspect and Replace Components

Sway Bar Links:
- Inspect for any wear or looseness.
- If damaged, remove the sway bar link using a socket wrench.
- Install the new sway bar link and torque it to the manufacturer’s specifications.
Struts and Shocks:
- Check for fluid leaks or physical damage.
- If necessary, remove the strut assembly by unbolting the top mount and lower attachment points.
- Replace with new struts/shocks and reassemble, ensuring all bolts are torqued to spec.
Control Arm Bushings:
- Inspect bushings for wear or separation.
- If needed, remove the control arm by unbolting it from the chassis and steering knuckle.
- Replace bushings or entire control arm, then reinstall and torque to spec.

4. Reassemble and Lower Vehicle

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Tighten the lug nuts to the specified torque.
