Ensure the engine is off, and allow any hot components to cool down.

2. Inspect and Tighten Suspension Components

Sub-steps:
1. Use a jack to raise the vehicle and secure it on jack stands.
2. Remove the wheels to access the suspension components.
3. Inspect all bolts and nuts associated with the suspension for tightness; refer to the service manual for torque specifications.
4. Use a torque wrench to tighten any loose fasteners to the manufacturer's specifications.

3. Replace Worn Suspension Parts

Sub-steps:
1. Identify any worn or damaged components (e.g., bushings, struts, or shocks).
2. If replacement is necessary, use appropriate tools (e.g., socket set, torque wrench).
3. Remove the worn component following the reverse order of installation.
4. Install the new part, ensuring it is secured to the correct torque specifications.
5. Reattach any other components removed during the process.

4. Reassemble and Lower the Vehicle

Sub-steps:
1. Reinstall the wheels and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and onto the ground.
3. Use the torque wrench to tighten the lug nuts to the manufacturer's specifications.
