Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Lift the Vehicle

Using a hydraulic jack, lift the vehicle and secure it with jack stands.
Remove the wheels for better access to suspension components.

3. Inspect and Replace Components

Bushings:
- Remove the control arms and sway bar links if bushings are worn.
- Replace with OEM or high-quality aftermarket bushings. Torque to manufacturer specifications.
Shock Absorbers:
- If shocks are leaking or not functioning properly, remove and replace them.
- Install new shocks, ensuring all mounting bolts are tightened to specified torque values.
Springs:
- Inspect coil springs for breaks or sagging; replace if necessary.

4. Lubrication

Apply appropriate lubricant to all moving parts of the suspension system, including bushings and joints, that are not sealed.

5. Reassemble

Reinstall wheels, ensuring all lug nuts are tightened to the specified torque.
Lower the vehicle from jack stands.
