2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and support it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Shock Absorbers

Inspection:
- Examine the shock absorbers for signs of leakage or damage.
Replacement:
- Remove the nuts securing the top of the shock absorber using a socket set.
- Remove the bolts at the bottom of the shock absorber.
- Replace with new shock absorbers, ensuring they are correctly aligned.
- Torque the bolts to the manufacturer's specifications (typically around 15-20 ft-lbs for top nuts and 30-40 ft-lbs for bottom bolts).

4. Check and Replace Sway Bar Links

Inspection:
- Check sway bar links for any signs of wear or looseness.
Replacement:
- Remove the bolts connecting the sway bar links to the sway bar and lower control arm.
- Install new sway bar links and torque the bolts to manufacturer specifications (usually around 25-30 ft-lbs).

5. Inspect and Replace Bushings

Inspection:
- Look for any cracked or worn bushings in the suspension system.
Replacement:
- Remove the components associated with the bushings (control arms, sway bar, etc.).
- Replace the old bushings with new ones, ensuring they are seated correctly.
- Reassemble all components and torque to manufacturer specifications.
