Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the recommended type of fluid if low (e.g., ATF or specific power steering fluid as per the owner's manual).
Check the fluid for contamination (milky appearance or debris).

3. Check for Leaks

Inspect the power steering pump, hoses, and connections for any signs of leaking fluid.
Clean any residue with a cloth and observe for new leaks after running the engine for a few minutes.

4. Test Power Steering Pump

Reconnect the battery and start the engine.
With the engine running, turn the steering wheel from lock to lock; listen for unusual noises.
Use a pressure gauge to test the power steering pump output, verifying it meets manufacturer specifications.

5. Inspect Steering Components

Visually check the steering rack for any signs of wear or damage.
Inspect the tie rod ends, ball joints, and bushings for play or damage.
Replace any worn or damaged components as needed.

6. Alignment and Tire Check

Verify that tire pressures are correct and that tires are evenly worn.
If necessary, perform a wheel alignment to ensure proper steering geometry.
