Solution

1. Preparation

Gather tools: jack, jack stands, socket set, wrench set, power steering fluid, and a torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level. If low, add the appropriate type of power steering fluid.
3. If the fluid is dark or contaminated, proceed to flush the system.
4. To flush, disconnect the return line from the power steering pump and drain the old fluid into a container.
5. Reconnect the line, fill the reservoir with new fluid, and turn the steering wheel back and forth to bleed air from the system.

3. Inspect and Replace Steering Rack

Sub-steps:
1. Raise the front of the vehicle using a jack and secure with jack stands.
2. Disconnect the tie rod ends from the steering rack.
3. Remove any mounting bolts securing the steering rack to the chassis.
4. Carefully slide the steering rack out and replace it with a new or remanufactured unit.
5. Reattach tie rod ends and torque all bolts to manufacturer specifications.

4. Examine and Replace CV Joints (if necessary)

Sub-steps:
1. Inspect CV joints for any cracks or tears in the boots.
2. If damaged, remove the axle by removing the axle nut and disconnecting it from the hub.
3. Install the new CV joint by reversing the removal process, ensuring proper alignment.
4. Re-torque the axle nut to the specified torque value.
