- Check all suspension-related bolts and nuts using a torque wrench.
- Refer to the manufacturer’s torque specifications for each component.
- Tighten any loose bolts to the specified torque values.

4. Replace Damaged Components

Sub-steps:
- If any components (e.g., struts, shocks, bushings) are found to be damaged:
  - Remove the affected component (e.g., strut assembly) by unbolting it from the lower control arm and top mount.
  - Install the new component, ensuring it is properly aligned.
  - Torque all fasteners to manufacturer specifications.
