Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical issues during repairs.

2. Inspect and Replace Wheel Bearings

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheel on the side where the noise is originating using a socket set.
3. Inspect the wheel bearing for play by shaking the wheel. If there is excessive movement, it needs replacement.
4. Remove the brake caliper (using a socket set) and hang it securely to prevent stress on the brake line.
5. Remove the rotor (if needed) to access the wheel bearing.
6. Use a bearing puller to remove the old bearing and install the new one.
7. Reassemble the rotor and brake caliper, ensuring all bolts are torqued to the manufacturer's specifications.

3. Check and Replace Suspension Components

Sub-steps:
1. Inspect the struts, shocks, and control arms for any signs of damage or wear.
2. If any components are damaged, remove them using a socket set.
3. Install new suspension components, ensuring they are properly aligned and torqued to specifications.
4. Recheck all bolts and components before lowering the vehicle.

4. Brake Inspection and Replacement

Sub-steps:
1. If the noise is related to braking, remove the wheel and inspect the brake pads and rotors.
2. Replace worn brake pads and resurface or replace the rotors if necessary.
3. Reassemble the brake system ensuring proper alignment and torque specifications.
