Solution

1. Preparation

Park the vehicle on a level surface, turn off the engine, and engage the parking brake.
Gather necessary tools and parts.

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 type of power steering fluid (e.g., ATF or specific PS fluid).
Replace the cap securely.

3. Inspect Power Steering Pump

Disconnect the negative battery terminal for safety.
Locate the power steering pump and inspect for leaks or damage.
If necessary, remove the drive belt by loosening the tensioner and sliding it off the pump pulley.
Using a pressure gauge, connect it to the power steering pump outlet and start the engine; check for proper pressure readings (typically around 1000-1200 psi under normal conditions).
If pressure is low, replace the power steering pump.

4. Check Steering Rack and Hoses

Inspect the steering rack for any signs of wear or leakage.
Check all hoses connected to the power steering system for cracks or loose fittings. Replace any damaged hoses as needed.
If the steering rack is faulty, it will need to be replaced.

5. Examine Drive Belt

Inspect the drive belt for cracks, fraying, or signs of wear.
If the belt is damaged, replace it with a new one, ensuring proper tension is applied according to manufacturer specifications.
