Sub-steps:
- Use a torque wrench to check and tighten all suspension-related bolts to manufacturer specifications (consult the owner's manual for specific torque values).
- Pay special attention to control arms, sway bar links, and shock absorber mounts.

4. Replace Worn Components

Sub-steps:
- If any suspension components (shocks, struts, bushings) are found to be worn, proceed to replace them.
- Remove the damaged parts using appropriate socket sizes and tools.
- Install new components, ensuring they are properly aligned and torqued.

5. Reassemble and Test
