Solution

1. Preparation

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

2. Inspect Power Steering Fluid

Remove the power steering reservoir cap.
Check the fluid level against the dipstick or markings on the reservoir.
If low, top off with the manufacturer-recommended power steering fluid.

3. Check for Leaks

Visually inspect all hoses and connections for signs of fluid leaks.
Clean any residual fluid with a rag and recheck after a test drive to confirm leaks.

4. Examine the Power Steering Belt

Locate the power steering belt; inspect for cracks, fraying, or excessive wear.
If damaged, loosen the tensioner and remove the old belt. Install a new belt, ensuring proper tension according to specifications.

5. Test Power Steering Pump

Start the engine while turning the steering wheel from lock to lock.
Listen for any abnormal noises from the pump. If noise persists, replace the power steering pump.
To replace, disconnect the power steering lines, remove mounting bolts, and install the new pump, ensuring to bleed the system of air afterward.

6. Inspect Steering Rack and Pinion

Check for any visible damage or leaks in the steering rack.
If damaged, remove the steering rack from the vehicle, replace it, and ensure proper alignment afterward.
