Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is suspected.
Secure the vehicle with jack stands to ensure stability.

3. Inspect Suspension Components

Front Suspension:
- Visually inspect control arms, bushings, and ball joints for damage.
- Check the sway bar links for tightness and signs of wear.
Rear Suspension:
- Repeat the inspection for rear control arms and bushings as well.

4. Check CV Joints

Inspect the CV axles for torn boots and listen for clicking noises while rotating the wheel.
If deterioration is found, the CV joint or axle may need to be replaced.

5. Replace Worn Components

If any components are found to be faulty:
- Remove the damaged part (e.g., sway bar link, control arm).
- Install the new part, tightening to the manufacturer’s specifications (typically around 37-50 ft-lbs for sway bar links).

6. Reassemble and Lower the Vehicle

Reinstall any components removed during inspection.
Lower the vehicle back to the ground and torque the wheel lug nuts to manufacturer specifications (usually 90-100 ft-lbs).
