Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather all necessary tools and replacement parts.
Safety gear: gloves and safety glasses.

2. Inspect and Tighten Suspension Components

Using a socket set, check the tightness of the bolts and nuts on shock absorbers, sway bar links, and control arms.
If any bolts are loose, tighten them to the manufacturer’s specifications.

3. Replace Worn Components

Tools Required: Socket set, wrench set, torque wrench, jack and jack stands, pry bar, and possibly a spring compressor if replacing struts.
If any damaged components are found (e.g., worn shocks, struts, or sway bar links):
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access the suspension components.
- Use a socket set to remove the nuts and bolts securing the worn component.
- Install the new component and torque to manufacturer specifications.
- Repeat for all affected components.

4. Final Inspection

Recheck all fasteners to ensure tightness and proper installation.
Reinstall the wheel and lower the vehicle.
