Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Power Steering Fluid

Tools Required: Funnel, clean rag.
Remove the power steering fluid reservoir cap and inspect the fluid.
If the fluid is low or contaminated, drain the old fluid and replace it with manufacturer-recommended power steering fluid.

3. Check and Replace Wheel Bearings

Tools Required: Jack and jack stands, socket set, torque wrench.
Lift the vehicle and secure it on jack stands.
Remove the wheel and inspect the wheel bearing for any roughness or play.
If damaged, remove the hub assembly and replace the wheel bearing according to manufacturer specifications (torque values typically around 80-100 ft-lbs).

4. Inspect and Replace CV Joints (if necessary)

Tools Required: Socket set, pry bar, grease.
Remove the axle nut and disconnect the CV joint from the wheel hub.
Inspect the CV boot for tears and the joint for wear.
If damage is found, replace the CV axle with a new unit, ensuring proper installation and torque specifications (usually around 30-50 ft-lbs).

5. Reassemble and Test

Reinstall all components in reverse order.
Reconnect the negative battery terminal.
Lower the vehicle and perform a thorough test drive to ensure the noise is resolved.
