Shock Absorbers:
- Remove the upper mounting bolts using a socket set.
- Inspect for signs of leakage; replace if necessary.
Sway Bar Links and Bushings:
- Remove the sway bar links by unscrewing the nuts.
- Check bushings for wear; replace if cracked or deteriorated.
Control Arm Bushings:
- Check for any cracking or excessive play; if worn, replace bushings.

4. Replace Damaged Parts

If any components are found faulty:
- Install new parts (shock absorbers, sway bar links, or control arm bushings) following the manufacturer’s specifications.
- Torque bolts to the manufacturer's specifications (refer to service manual for exact torque values).

5. Reassemble and Lower Vehicle

Reattach any components removed for inspection.
Remove jack stands and lower the vehicle back to the ground.
