Solution

1. Preparation

Gather necessary tools and park the vehicle on a level surface.
Wear safety gloves and goggles for protection.

2. Raise the Vehicle

Use a floor jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure stability.

3. Inspect and Replace Shock Absorbers/Struts

Inspection:
- Remove the wheel to access the shock absorber/strut assembly.
- Check for leakage and physical damage.
Replacement:
- Unbolt the top mount of the strut using a socket wrench.
- Remove the lower mounting bolts.
- Install the new shock absorber/strut in reverse order.
- Torque the mounting bolts to the manufacturer's specifications (typically around 50-70 ft-lbs).

4. Inspect and Replace Sway Bar Links/Bushings

Inspection:
- Locate the sway bar links and bushings.
- Check for cracks, excessive play, or wear.
Replacement:
- Remove the nuts securing the sway bar link to the sway bar and lower control arm.
- Install the new sway bar link and torque to specifications (usually around 30-40 ft-lbs).

5. Final Assembly

Reinstall the wheel and lower the vehicle.
Tighten lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).
