Solution

1. Preparation

Tools Required: OBD-II scanner, fluid catch pan, socket set, torque wrench.
Park the vehicle on a level surface, turn off the engine, and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir; typically found near the engine bay.
2. Remove the cap and check the fluid level against the dipstick.
3. If low, add the recommended power steering fluid (consult owner's manual for specifications).
4. Replace the cap securely after filling.

3. Inspect Power Steering Pump

Sub-steps:
1. Visually inspect the power steering pump for leaks or physical damage.
2. Check the drive belt for signs of wear or looseness; replace if necessary.
3. If the pump is faulty, remove it by unbolting it from the mounting bracket and disconnecting the fluid lines.
4. Install the new pump by reversing the removal procedure and torquing the bolts to the manufacturer’s specifications.

4. Check Steering Rack and Linkages

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect the steering rack for leaks and damage, and check for any play in the tie rods.
3. If the steering rack is faulty, disconnect it from the tie rods and unbolt it from its mounting points.
4. Install the new steering rack and reconnect all linkages, tightening bolts to the specified torque.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and turn the steering wheel from lock to lock to bleed any air from the system if the fluid was low or changed.
Check for any leaks around the power steering components.
