Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check Power Steering Fluid

Tools Required: None
Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If the fluid is low, top it off with the manufacturer-recommended power steering fluid.

3. Inspect Power Steering Pump

Tools Required: Socket set, torque wrench
Remove any covers obstructing access to the power steering pump.
Visually inspect the pump for any signs of leakage or damage.
If leaks are found, replace the power steering pump by:
- Disconnecting the fluid lines (using a container to catch any spilled fluid).
- Unbolting the pump from its mounting bracket.
- Installing the new pump and reconnecting the fluid lines, ensuring all connections are tight.

4. Check Steering Rack

Tools Required: Socket set, possibly a steering rack removal tool
Inspect the steering rack for any leaks or damage.
If damage is found, replace the steering rack by:
- Disconnecting the tie rod ends.
- Unbolting the steering rack from its mounts.
- Installing the new steering rack and reattaching all connections.

5. Inspect Drive Belt

Tools Required: None
Check the drive belt for wear or slack. Ensure proper tension.
If the belt is worn or loose, replace it by:
- Loosening the tensioner and removing the old belt.
- Installing the new belt around the pulleys and adjusting the tension to specifications.
