Disconnect the battery to prevent any electrical issues.

2. Check Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect the fluid level; if low, refill with manufacturer-recommended power steering fluid.

Use a socket set to disconnect the power steering hose clamps.
Inspect hoses for cracks or leaks.
If damaged, replace with new hoses, ensuring all connections are tight.

4. Examine the Power Steering Pump

Locate the power steering pump (usually near the engine).
Check for any signs of leaks or damage.
If the pump is noisy or not functioning, remove it using a socket set and replace with a new pump.
- Sub-steps:
  - Disconnect the pump from the belt using a wrench.
  - Remove the mounting bolts and take out the old pump.
  - Install the new pump and secure it with mounting bolts.

5. Check the Steering Rack

Inspect the steering rack for any signs of wear or leaks.
If damaged, replace the steering rack:
- Disconnect the steering column from the rack.
- Remove the rack mounting bolts and carefully take out the rack.
- Install the new steering rack and reconnect all components.

6. Refill and Bleed the System

Refill the power steering fluid reservoir.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
Check fluid levels and top off if necessary.
