Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, inspection mirror, pry bar.
Safety Warnings: Ensure the vehicle is on a flat surface and use jack stands for safety. Wear safety glasses when inspecting.

2. Remove Wheels

Loosen lug nuts with a socket set while the vehicle is on the ground.
Raise the vehicle using a jack and secure it on jack stands.
Remove lug nuts completely and take off the wheels.

3. Inspect and Replace Suspension Components

Sway Bar Links:
- Use a wrench to remove the bolts securing the sway bar links to the sway bar and lower control arm.
- Inspect for wear and replace if necessary.
Shocks/Struts:
- Remove the top nut securing the shock/strut assembly in the engine bay.
- Detach the lower mount bolts from the control arm.
- Replace with new shocks/struts if worn.
Control Arm Bushings:
- Use a pry bar to check for play in the control arms.
- Replace bushings if they show signs of excessive wear or damage.

4. Reassemble and Torque Components

Reinstall all components in the reverse order of removal.
Ensure all bolts and nuts are torqued to manufacturer specifications using a torque wrench.

5. Reinstall Wheels

Place wheels back on the hubs and hand-tighten lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the specified torque.
