Solution

1. Preparation

Gather tools and parts required for repair.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Worn Components

Sway Bar Links:
- Remove the nuts securing the sway bar links using a socket set.
- Replace with new sway bar links if damaged or worn, ensuring proper torque according to manufacturer specifications.
Shock Absorbers:
- Detach the top and bottom mounting bolts of the shock absorber.
- Replace with new shocks if they are leaking or not functioning properly. Torque bolts to manufacturer specifications.
Control Arm Bushings:
- Remove the control arm if bushings are worn, using a socket set to take out the bolts.
- Press in new bushings or replace the entire control arm assembly.

4. Reassemble and Lower the Vehicle

Reattach any components that were removed during inspection.
Ensure all bolts are tightened to proper torque specifications.
Carefully lower the vehicle back to the ground.
