Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Suspension Components

Inspect Struts/Shocks:
- Examine the struts and shocks for leaks or physical damage.
- If damaged, remove the strut assembly by loosening the top mount bolts and lower mounting bolts.
- Replace with new struts/shocks, ensuring proper alignment of the top and bottom mounts.
Check Control Arm Bushings:
- Inspect control arm bushings for cracks or deterioration.
- If worn, remove the control arm by unscrewing the bolts and replace with new bushings or control arms as necessary.
Examine Sway Bar Links:
- Check sway bar links for play or broken components.
- If defective, remove and replace with new sway bar links.

4. Reassemble and Lower Vehicle

Reinstall any components that were removed during inspection.
Torque all bolts to manufacturer specifications (check service manual for exact torque values).
Lower the vehicle safely back to the ground.
