Solution

1. Preparation

Gather tools: socket set, wrench set, power steering fluid, funnel, and OBD-II scanner.
Park the vehicle on a level surface and engage the parking brake.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
If the fluid is low, top it off with the recommended type of power steering fluid.
Start the engine and turn the steering wheel from lock to lock to circulate the new fluid.

3. Inspect and Replace Power Steering Belt

Tools Required: Socket set and torque wrench.
If the belt is worn or loose:
1. Remove the belt by loosening the tensioner pulley.
2. Replace it with a new belt, ensuring it is properly aligned on all pulleys.
3. Tighten the tensioner to the manufacturer's specified torque.

4. Repair or Replace Power Steering Pump (if necessary)

Tools Required: Socket set, wrench set, and fluid catch pan.
If leaks are found or the pump is noisy:
1. Disconnect the battery.
2. Remove the power steering pump by disconnecting the hoses and mounting bolts.
3. Install the new pump and reconnect the hoses, ensuring there are no leaks.
4. Reconnect the battery.

5. Bleed the Power Steering System

Start the engine and turn the steering wheel from lock to lock to remove air from the system.
Check fluid levels again and top off if necessary.
