Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; top off with manufacturer-recommended fluid if low.
If the fluid is dirty or burnt, perform a fluid flush:
- Disconnect the return line from the pump.
- Use a turkey baster to remove old fluid from the reservoir.
- Reconnect the line and fill the reservoir with new fluid.
- Start the engine and turn the steering wheel to bleed the system.

3. Inspect and Replace Worn Components

CV Joints:
- Raise the vehicle using jack stands.
- Inspect the CV joint boots for cracks or tears.
- If damaged, remove the axle nut and the axle from the hub to replace the CV joint.
Wheel Bearings:
- Remove the wheel and brake assembly.
- Inspect for play by shaking the hub; replace if necessary.
- To replace, remove the hub assembly and install a new bearing.
Tie Rods and Ball Joints:
- Inspect for wear or looseness.
- If replacement is needed, remove the cotter pin and nut, and use a tie rod puller to remove the tie rod.
- Install the new component and torque the nuts to manufacturer specifications.

4. Reassemble and Test

Reattach all components removed during inspection.
Check torque specifications on all bolts and nuts.
Lower the vehicle and reconnect the battery.
Start the vehicle and test drive to ensure noise is resolved.
