Solution

1. Preparation

Gather tools: jack, jack stands, wrench set, socket set, and a spray lubricant.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.

2. Inspect Suspension Components

Step 1: Remove the front and rear wheels to gain access to suspension components.
Step 2: Visually inspect control arms, bushings, and shocks for signs of damage or wear.
Step 3: Check sway bar links for any play and inspect bushings for deterioration.

3. Replace Worn Components

Step 1: If any components are found to be worn, replace them as follows:
- Control Arms: Remove the bolts securing the control arm and replace with a new unit. Torque to manufacturer specifications (typically around 50-60 Nm).
- Shock Absorbers: Remove the bolts securing the shock, replace with new shocks, and torque bolts to specifications (usually around 80-100 Nm).
Step 2: Replace sway bar bushings and links if they are damaged. Use a lubricant on the new bushings to prevent future squeaks.

4. Lubrication

Step 1: Apply a suitable lubricant to all moving parts, including bushings and joints.
Step 2: Ensure excess lubricant is wiped away to avoid attracting dirt.

5. Reassemble and Lower Vehicle

Step 1: Reinstall the wheels and torque lug nuts to specifications (usually around 120 Nm).
Step 2: Lower the vehicle and perform a final check of all components.
