why is my Toyota Corolla E170 (2013-2019) steering wheel so hard to turn?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and turn off the engine.
• Disconnect the battery to ensure safety.

2. Check Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level; top up with the manufacturer-recommended power steering fluid if low.
• Inspect fluid for contamination (dark color or debris).

3. Inspect Power Steering Pump

• Locate the power steering pump and check for leaks around the seals.
• If leaks are present, proceed to replace the power steering pump.
  • Sub-steps:
    • Remove the drive belt from the power steering pump.
    • Disconnect the fluid lines from the pump using a wrench.
    • Unbolt the pump from its mounting bracket and remove it.
    • Install the new pump and reconnect the fluid lines and drive belt.

4. Examine Drive Belt

• Inspect the drive belt for cracks, fraying, or signs of wear.
• Replace the belt if it is damaged.
  • Sub-steps:
    • Loosen the tensioner pulley to relieve tension on the belt.
    • Remove the old belt and install the new one, ensuring proper routing.
    • Tighten the tensioner pulley to the manufacturer's specifications.

5. Test Steering System

• Reconnect the battery.
• Start the engine and turn the steering wheel to verify smooth operation.
• Check for any leaks around the power steering pump and fluid lines.
