why is my Toyota Corolla E170 (2013-2019) making a groaning noise when I turn the steering wheel?

Solution

1. Preparation

• Gather tools: socket set, wrench set, power steering fluid, funnel.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Top Up Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level against the dipstick.
• If low, add the appropriate type of power steering fluid (check owner’s manual for specifications).

3. Check for Leaks

• Visually inspect all power steering lines and the pump for signs of leaks.
• If leaks are found, tighten fittings or replace damaged hoses.

4. Inspect the Power Steering Pump

• Locate the power steering pump and check for noise while the engine is running.
• If the pump is noisy or not functioning correctly, it may need to be replaced.

5. Check Steering Rack and Linkage

• Inspect the steering rack for signs of wear or hydraulic fluid leakage.
• Examine the tie rods and steering linkage for any play or damage.
• Replace any worn components as necessary.

6. Reassemble and Test

• Reconnect the battery.
• Start the engine and turn the steering wheel from lock to lock to bleed any air from the system.
• Monitor for any noise and check the fluid level again, topping off as necessary.
