Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Raise the front of the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Damaged Components

Shock Absorbers:
- Remove the wheel to access the shock absorber.
- Unbolt the top mount of the shock absorber and the lower mounting bolts.
- Replace with new shock absorbers if they show signs of leakage or damage.
Sway Bar Links:
- Inspect sway bar links for wear or damage.
- Remove the bolts securing the sway bar links to the sway bar and control arm.
- Replace with new sway bar links and secure with torque as specified by manufacturer (typically 30-40 ft-lbs).
Control Arms and Ball Joints:
- Check for excessive play in control arms and ball joints.
- If play is detected, remove the control arm by unbolting it from the subframe and steering knuckle.
- Replace the control arm and ball joint assembly as needed, ensuring all bolts are torqued to manufacturer specifications.

3. Final Assembly

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