Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use safety glasses and gloves.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Components

Inspect Shock Absorbers:
- Remove the wheel for access.
- Check for any oil leakage or physical damage.
- If damaged, remove the shock absorber by unbolting the top and bottom mounts.
- Replace with new shock absorbers, ensuring to torque the bolts to manufacturer specifications (typically around 40-50 Nm).
Check Sway Bar Links and Bushings:
- Inspect sway bar links for wear; replace if there is excessive play.
- Remove the sway bar links using a socket set.
- Replace worn bushings using a bushing removal tool, and apply grease to new bushings before installation.
Examine Control Arms:
- Check lower control arms for cracks or wear in the bushings.
- If needed, remove the control arm by loosening the bolts and replace with a new component, ensuring to torque bolts to specifications.

4. Reassemble and Lower Vehicle

Reattach wheels and ensure all fasteners are properly torqued.
Lower the vehicle off the jack stands.
