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 for protection.

2. Inspect Suspension Components

Raise the vehicle using a jack and secure it on jack stands.
Visually inspect control arms, bushings, and struts for signs of wear or cracks.
If any components are damaged, proceed to replace them.

3. Check Brake Components

Remove the wheel to access the brakes.
Inspect brake pads for thickness and wear; replace if less than 3mm.
Check brake rotors for grooves or warping; replace if necessary.
Apply brake grease to the back of the brake pads to minimize squeaking.

4. Inspect and Lubricate Moving Parts

Inspect all moving parts such as sway bar links and bushings.
Apply appropriate grease to bushings and joints as needed.
Ensure all bolts are torqued to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and lug nuts, torquing to manufacturer specifications.
Carefully lower the vehicle from the jack stands.
