Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to ensure safety while working on electrical components.

2. Inspect and Replace Worn Components

Inspect Steering Components:
- Remove the front wheel on the side where the noise is prominent using a socket set.
- Check the tie rod ends, ball joints, and steering rack for signs of wear or damage.
- Replace any damaged components with OEM parts.
Inspect CV Joints and Axles:
- If CV joints are worn, remove the axle nut and disconnect the axle from the hub.
- Inspect the CV boot for tears and replace the entire axle assembly if the joint is damaged.

3. Reassemble and Reconnect

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically around 100-120 ft-lbs).
Reconnect the 12V battery.
Ensure all components are securely fastened and double-check for any loose parts.
