Solution

1. Preparation

Gather tools and parts required.
Lift the vehicle using a jack and secure it on jack stands.
Ensure the vehicle is on a flat, stable surface.

2. Inspect and Replace Worn Components

Inspect Shock Absorbers
- Check for oil leakage; if present, replace the shock absorbers.
- Tools required: Socket set, torque wrench.
Replace Sway Bar Links
- Remove the sway bar link bolts using the socket set.
- Install new sway bar links, tightening to the manufacturer's specified torque (typically around 40-50 ft-lbs).
Inspect Control Arms and Bushings
- Check for cracks or excessive wear on control arm bushings; replace if necessary.
- If bushings are worn, remove the control arm and replace bushings using a press (if required).

3. Reassemble and Lower Vehicle

Reinstall any removed components and ensure all bolts are torqued to specification.
Remove jack stands and lower the vehicle carefully.
