Solution

1. Preparation

Tools Required: Socket set, torque wrench, fluid catch pan, power steering fluid.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, add the recommended power steering fluid until it reaches the proper level.
Inspect the fluid condition; if it appears dirty or contaminated, a fluid flush may be necessary.

3. Inspect and Replace Power Steering Pump (if needed)

Tools Required: Wrench set, power steering pulley puller, new power steering pump.
Remove the serpentine belt by loosening the tensioner.
Disconnect the power steering hoses from the pump, allowing fluid to drain into the catch pan.
Unbolt the power steering pump from its mounting bracket and remove it from the engine bay.
Install the new power steering pump by reversing the removal steps and ensuring all connections are secure.

4. Check Steering Rack and Tie Rods

Inspect the steering rack for any signs of internal damage or leaks.
Check the tie rods and ball joints for play or wear using a pry bar.
If any components are worn, replace them using appropriate tools and torque specifications.

5. Reassemble and Test

Reattach all components in reverse order.
Reconnect the negative battery terminal.
Start the engine, turn the steering wheel from lock to lock, and check for any noises.
Ensure the power steering fluid is at the correct level after any work.
