Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Sub-steps:
1. Use a jack to lift the front or rear of the vehicle, depending on the location of the noise.
2. Securely position jack stands under the vehicle for safety.

Sub-steps:
1. Sway Bar Links:
  - Use a socket set to remove the nuts securing the sway bar links.
  - Inspect for wear; replace if damaged.
  - Install new sway bar links and torque bolts to manufacturer specifications (typically 40-50 ft-lb).
2. Control Arm Bushings:
  - Remove the control arm from the vehicle by taking out the mounting bolts.
  - Inspect the bushings for wear; replace if necessary.
  - Reinstall the control arm and torque bolts as per specifications (usually 100-120 ft-lb).
