1. Visually inspect the struts or shocks for any leaks or physical damage.
2. Use a pry bar to check for play in the control arm bushings and ball joints.
3. Check the mounting bolts for tightness and torque them to the manufacturer specifications (consult repair manual for torque values).

4. Replace Worn Components

Sub-steps:
1. If any components are found to be damaged or worn, remove the affected parts (e.g., struts, shocks, control arms).
2. Install new components, ensuring they are properly aligned and torqued to specifications.
3. Ensure that all bushings are replaced if they show signs of wear.

5. Reassemble and Lower the Vehicle

Sub-steps:
