Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather tools and safety equipment (gloves, safety glasses).
Disconnect the negative battery cable if working on electrical components.

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
If the fluid is low, top off with the manufacturer-recommended fluid.
If the fluid appears dark or contaminated, proceed to replace it:
- Drain the old fluid from the reservoir.
- Refill with new power steering fluid and run the engine briefly to circulate.
- Check for leaks after filling.

3. Inspect and Replace Worn Components

Check tie rod ends and ball joints:
- Raise the front of the vehicle using a jack and secure on jack stands.
- Use a socket set to remove any protective covers.
- Check for play by moving the components and replace if necessary.
For CV joints, inspect the boots for tears and replace if damaged:
- Remove the wheel for access.
- Disconnect the axle from the wheel hub.
- Replace the CV joint or the entire axle assembly if needed.

4. Wheel Bearing Inspection and Replacement

With the wheel removed, grasp the wheel hub and check for play.
If there is play, disassemble the hub assembly:
- Remove the brake caliper and rotor.
- Unscrew and remove the wheel bearing assembly.
- Install a new wheel bearing by reversing the removal steps, ensuring proper torque specifications (typically 35-50 ft-lbs).

5. Reassemble and Test

Reassemble all components in reverse order.
Ensure all nuts and bolts are torqued to manufacturer specifications.
Reconnect the negative battery cable.
Lower the vehicle and perform a test drive to verify the noise has been resolved.
