Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Replace Suspension Components

Inspect Shock Absorbers:
- Remove the wheel using a socket set.
- Check for oil leakage around the shock absorbers.
- If damaged, replace with new shock absorbers.
Check Sway Bar Links:
- Locate the sway bar links connected to the sway bar and lower control arm.
- If the links are worn or damaged, remove them using a wrench and socket.
- Install new sway bar links and torque to manufacturer's specifications (typically around 30-40 Nm).

3. Tighten Loose Components

Tighten Suspension Bolts:
- Using a torque wrench, check and tighten all suspension bolts to the specified torque values (consult service manual for exact figures).
Inspect Control Arms:
- Check control arm bushings for wear.
- If worn, replace the control arms and torque their bolts to specifications.

4. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Conduct a test drive to ensure the rattling noise is resolved.
