Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool down if it has been recently driven.

2. Inspect Suspension Components

Sub-steps:
- Lift the vehicle using a hydraulic jack and secure it with jack stands.
- Visually inspect struts and shocks for leaks or damage.
- Check control arms and bushings for wear or corrosion.
Tools Required: Hydraulic jack, jack stands, flashlight.

3. Tighten or Replace Loose Hardware

Sub-steps:
- Use a socket set to check and tighten all bolts related to the suspension components.
- If any bolts are stripped, replace them with OEM parts.
Tools Required: Socket set.

4. Replace Worn Components

Sub-steps:
- If any suspension components are found to be damaged or worn, proceed with removal:
  - Remove the wheel to access suspension components.
  - Detach the strut or shock absorber by unbolting it from the control arm and upper mounts.
  - Install the new strut/shock and secure with manufacturer-specified torque settings.
Tools Required: Socket set, torque wrench, possibly a spring compressor if replacing struts.

5. Reassemble and Lower Vehicle

Sub-steps:
- Reattach the wheel and secure all lug nuts to the manufacturer's torque specifications.
- Lower the vehicle from the jack stands and remove the jack.
Tools Required: Torque wrench.
