- Inspect control arms, ball joints, and bushings for signs of wear or damage.
- Check shock absorbers for leaks or physical damage.

3. Tighten Loose Components

Sub-steps:
- Use a torque wrench to tighten suspension bolts to the manufacturer's specified torque settings (refer to vehicle service manual).
- Inspect and tighten any loose underbody panels or trim that may be rattling.

4. Replace Worn Components (if necessary)

Sub-steps:
- If any suspension components are found to be damaged, remove them using appropriate tools (e.g., socket set, wrenches).
- Replace with OEM or high-quality aftermarket parts.
- Reassemble components, ensuring all bolts are torqued to specification.
